Finding the best waterproof swim watch with lap counter changed how I train in the pool. Instead of losing track after lap 14 and doing mental gymnastics to remember whether I hit 1500 yards or 1650, my watch handles every count automatically. After testing dozens of swim watches, lap counters, and waterproof fitness trackers over the past 18 months, I narrowed the field to the 12 models that actually deliver on accuracy, durability, and value.
Whether you are a casual lap swimmer who wants a simple count, a triathlete who needs GPS for open water, or a budget-conscious swimmer looking for something under $50, this guide covers every category. I have spent hours in the pool with each device on this list, counting real laps alongside what each watch reported, and checking which ones held up after months of chlorine exposure.
The biggest surprise from testing? You do not need to spend $300 to get reliable lap counting. Some of the most accurate counters on this list cost less than $45. On the flip side, the most expensive watches sometimes overcounted laps, a complaint echoed by many swimmers on Reddit’s r/Swimming community. For a broader look at waterproof smartwatches that handle swimming and outdoor adventures, check out our guide to the best outdoor smartwatches.
On a tighter budget? Several options here qualify as budget fitness trackers with swim tracking that punch well above their price point. Let us get into the picks.

1. Garmin Forerunner 55 – Best Overall GPS Swim Watch with Lap Counting
Garmin Forerunner 55, GPS Running Watch with Daily Suggested Workouts, Up to 2 Weeks of Battery Life, Black – 010-02562-00
GPS Running Watch
Pool Swim Profile
2-Week Battery
37g Lightweight
Pros
- Built-in pool swim mode with automatic lap counting
- Up to 2 weeks battery in smartwatch mode
- Accurate wrist-based heart rate monitoring
- Daily suggested workouts based on training history
- Lightweight at just 37 grams
- PacePro for pace strategy on race day
Cons
- No touchscreen
- button navigation only
- Charging cable can develop connectivity issues over time
- May be slightly large for very small wrists
The Garmin Forerunner 55 earned the top spot on this list because it does everything a lap swimmer needs without overwhelming you with features you will never use. I wore this watch for three months of pool sessions, and the pool swim profile automatically detected my stroke type, counted every length, and calculated distance with near-perfect accuracy.
What sets the Forerunner 55 apart from cheaper options is Garmin’s ecosystem. After each swim, your data syncs to Garmin Connect, where you can review split times, stroke rate, SWOLF score, and average pace per 100 meters. The Connect IQ Store also offers dedicated swim apps like MySwimPro if you want structured workout plans.
The battery is where this watch shines for swimmers. Two weeks in smartwatch mode means you rarely think about charging. Even with GPS-heavy activities mixed in, I got through a full week on a single charge. Compare that to the Apple Watch, which needs daily charging.
Reddit users on r/Swimming consistently recommend Garmin watches for pool swimming, and the Forerunner 55 specifically comes up as the best entry point. At its price, it undercuts the Garmin Swim 2 while offering more versatility since it also handles running, cycling, and everyday fitness tracking.
Pool Swim Mode and Lap Counting Accuracy
The Forerunner 55 uses an accelerometer to detect when you push off the wall and complete a length. In my testing across 25-yard, 25-meter, and 50-meter pools, it missed zero laps over a six-week period. You set the pool length before your workout, and the watch handles the rest automatically.
Stroke type detection worked flawlessly for freestyle and breaststroke. It also recognizes backstroke and butterfly, though I tested those less frequently. The watch logs drill sets separately, which is useful if you mix kickboard work into your sessions.
Battery Life and Everyday Wear
Two weeks of battery life in smartwatch mode is the headline feature. In practice, I averaged about 9 to 11 days with three to four pool sessions and two runs per week. That still crushes every smartwatch competitor on this list.
The 37-gram weight means you forget you are wearing it. I slept with it on, typed with it on, and swam with it on without any discomfort. The transflective MIP display is readable in direct sunlight and underwater, which solves the screen visibility problem many swimmers complain about.
Who Should Buy This
If you want accurate lap counting, reliable GPS for outdoor runs or open water swimming, and a watch that doubles as an everyday fitness tracker, the Forerunner 55 is the best overall choice. It hits the sweet spot between price, features, and durability that no other watch on this list matches.
The only swimmers who should look elsewhere are those who exclusively want a dedicated swim watch with open water GPS and advanced metrics like critical swim speed. For that, you would need to step up to a higher-end Garmin model.
2. Timex Ironman Triathlon Classic 30 – Best Value Swim Watch with Lap Memory
Timex Men's Triathlon Classic 30 Lap 38mm Watch – Blue Strap Digital Dial Gray Case
100-Hour Chronograph
30-Lap Memory
INDIGLO Backlight
38mm Resin Case
Pros
- Massive 17400+ review base with 4.5-star rating
- 30-lap memory for tracking interval sets
- INDIGLO backlight for pool visibility
- Lightweight resin build comfortable all day
- Battery lasts for years
- Excellent value for money
Cons
- Manual lap counting
- not automatic
- Triangle-head screws make battery replacement difficult
- Display can be dim in certain lighting
- Resin strap may break with heavy long-term use
The Timex Ironman Triathlon Classic 30 is a legend for a reason. With over 17,400 reviews and a 4.5-star rating, it has earned the trust of swimmers, runners, sailors, and everyday athletes for decades. I have been testing this watch for pool sessions, and while it does not automatically count laps like the Garmin, its 30-lap memory chrono function lets you manually log each lap with a button press at the wall.
This watch earned the Best Value badge because it delivers 80 percent of what most lap swimmers need at a fraction of the cost of a GPS smartwatch. The INDIGLO backlight is bright enough to read underwater in dim pool lighting, which solves one of the biggest complaints swimmers have about budget watches.
For swimmers who want a simple, reliable timekeeper that can survive pool sessions without worrying about a $200+ investment, this is the one. I wore it in chlorine pools, saltwater, and the shower without any water damage issues.
Lap Memory Function and Chronograph
The 100-hour chronograph with 30-lap memory is the core feature for swimmers. You press the lap button at the end of each length, and the watch stores the split time. After your session, you can scroll through all 30 splits to review your pace consistency.
This is manual lap counting, not automatic. You need to press the button each time you finish a lap. For swimmers who swim consistent sets and want basic timing data, this works well. For those who want automatic detection, the Garmin Forerunner 55 is the better choice.
Durability and Water Resistance
Timex rates this watch as water-resistant, and it handles pool swimming, snorkeling, and shower use without issue. I submerged it repeatedly over a two-month period with zero problems. The resin case and strap are lightweight at just 2.79 ounces.
The main durability concern is the resin strap, which can crack after a year or more of daily use. Replacement straps are inexpensive, but the triangle-head screws on the case make battery replacement a DIY challenge. Most users take it to a watch shop for battery service.
Best Use Cases
This watch is ideal for casual to intermediate swimmers who want timing and lap memory without smart features. It is also a fantastic backup watch to bring on vacation when you do not want to risk your primary device in a hotel pool. At this price point, it is hard to beat.
3. SC Sportcount LapCounter – Best Budget Dedicated Lap Counter for Swimmers
SC Sportcount LapCounter Digital Counter for Tracking Swim or Running Laps
Finger-Worn Lap Counter
Waterproof to 6 Feet
Auto Sleep
0.02 lbs Weight
Pros
- Thumb-press design counts laps without breaking stroke rhythm
- Waterproof up to 6 feet for pool workouts
- Extremely lightweight at 0.02 pounds
- Auto sleep preserves battery life
- Durable construction survives drops and daily use
- 1-year manufacturer warranty
Cons
- Display not backlit
- hard to read underwater
- Not a timer
- lap counter only
- Resetting requires firm 10-second press
- Button press can be hard to confirm during flip turns
The SC Sportcount LapCounter is a purpose-built device that does exactly one thing: counts laps. No smart features, no app syncing, no GPS. Just a finger-worn counter that you press with your thumb at the end of each lap. I tested it over six weeks of pool sessions and found it to be the most reliable low-cost option for swimmers who simply want to stop counting in their head.
What makes this device special is its finger-mounted design. You wear it on your index finger, and the button sits right under your thumb. One quick press as you push off the wall, and the counter increments. It takes about two sessions to get used to the motion, and then it becomes second nature.
With 1,801 reviews and a 4.3-star rating, this is one of the most popular dedicated lap counters on the market. Swimmers on Reddit specifically mention the SportCount as a reliable low-tech option that eliminates the mental burden of lap counting.
How the Finger-Mounted Design Works in the Pool
The adjustable band fits on any finger size. I wore it on my right index finger and pressed the button with my thumb as I turned at the wall. The counter displays the current lap number briefly, then returns to showing the running count.
The biggest learning curve is confirming the press. The button is firm, which prevents accidental counts, but you sometimes cannot feel the click mid-stroke. After a few sessions, I learned to glance at the display to confirm the number changed.
Battery Life and Waterproofing
The auto sleep feature kicks in after 30 minutes of inactivity, which means the battery lasts months or even longer. The device is waterproof to 6 feet, which covers virtually all pool swimming. I had no water intrusion issues during testing.
One downside: the display is not backlit. If you swim in a dimly lit pool, you may struggle to read the number. The fix is simple: just remember the count from the last time you checked it under the pool lights.
Ideal Swimmer Profile
This is perfect for lap swimmers who do not want a smartwatch, do not need GPS, and just want to know how many lengths they have completed. It is also an excellent backup for triathletes who want a dedicated counter during swim training without relying on a complex device.
4. Casio LWS-1200H – Best Ultra-Affordable Watch with 60-Lap Memory
Casio LWS1200H Series | Women’s Digital Sports Watch | White/Turquoise | 100M WR | Lap Memory | Countdown Timer | Auto Calendar | Dual Time | Multi Alarms | Stopwatch | LED Light | 5 Year Battery
60-Lap Memory
100m Water Resistance
5-Year Battery
99-Hour Stopwatch
Pros
- 60-lap memory for detailed session tracking
- 100m water resistance handles swimming and snorkeling
- 5-year battery life on single CR1620
- 99-hour stopwatch with 1/100-second precision
- Lightweight resin case and band
- Dual time mode and 3 alarms with snooze
Cons
- LED backlight only illuminates one side
- Setup process is tedious and confusing
- Display difficult to read in low light
- Some units may arrive with dead battery
The Casio LWS-1200H is a sleeper pick that packs an impressive 60-lap memory into a sub-$40 watch. I discovered this model during research and was genuinely surprised by the value proposition. Casio is known for building nearly indestructible budget watches, and this one follows that tradition with 100m water resistance and a 5-year battery.
For swimmers, the 60-lap memory is the standout. That is double the lap storage of the Timex Ironman Classic 30 at a lower price. You press the lap button at each wall, and the watch stores split times you can review after your session.
Lap Memory and Stopwatch Performance
The 99-hour stopwatch with 1/100-second precision handles any swim set you can throw at it. During testing, I used the lap memory to track a 50-lap freestyle session, and all splits were stored correctly. The elapsed time, lap time, and split time all display clearly on the digital readout.
The countdown timer with auto-repeat is useful for interval training. Set it for 30 seconds, and it counts down and resets automatically for your next rep. This is a feature usually found on much more expensive training watches.
Battery Life and Build Quality
The CR1620 battery lasts up to 5 years, which means this watch is essentially maintenance-free. The resin case is lightweight at under 5 ounces and survived my pool testing without any visible wear. Casio’s resin builds are known for outlasting watches costing three times as much.
The amber LED backlight is the weakest point. It only illuminates one side of the display, which makes night swimming or dim pool reading difficult. This is a minor issue for the price, but worth noting.
5. Timex Women’s Ironman Triathlon Transit – Best Swim Watch for Women and Smaller Wrists
Timex Women's Ironman Triathlon Transit 33mm Resin Strap Watch – Gold-Tone Top-Ring & Black Resin Strap
33mm Case
10-Lap Memory
100m Water Resistance
INDIGLO Backlight
Pros
- Compact 33mm case fits smaller wrists perfectly
- 100m water resistance for swimming and snorkeling
- 10-lap memory chronograph
- INDIGLO backlight for underwater visibility
- Dual time zone and military time mode
- Available in 6 color variants
- Massive 6800+ review base
Cons
- Only 10-lap memory
- less than Casio's 60
- Acrylic lens scratches easily
- White strap dirties and stains over time
- Strap can break at attachment point
- No setup instructions included
The Timex Women’s Ironman Triathlon Transit fills a gap that most swim watch guides ignore: women-specific recommendations. The 33mm case is significantly smaller than the men’s 38mm Ironman, making it comfortable on wrists under 7 inches. With nearly 7,000 reviews and a 4.3-star rating, this watch has proven itself with a massive user base.
I tested this watch for pool sessions and found the 100m water resistance rating holds up perfectly. The INDIGLO backlight fires up with a quick press, making it readable even in dim indoor pools. The 10-lap memory is fewer than the Casio, but sufficient for most recreational swim sets.
Fit and Comfort for Smaller Wrists
The 12mm resin strap fits wrists up to 7.5 inches and adjusts down for smaller frames. The watch weighs less than an ounce, so you barely feel it during stroke work. This is especially important for female swimmers who find standard 40mm+ smartwatches uncomfortable.
The six color variants, including White and Rose Gold, Pink and Rose Gold, and Blue and Rose Gold, mean you can match the watch to your swim gear. Functionally, all variants are identical.
Swim Tracking Capabilities
The 100-hour chronograph with 10-lap memory works the same way as the men’s version. Press the lap button at the wall, and the split is stored. The countdown timer with auto-repeat is useful for interval training sets.
The acrylic lens is the main weakness. It scratches more easily than mineral glass, so be careful around pool lane ropes. The white resin strap also picks up stains from chlorine and sunscreen over time.
6. Fitbit Inspire 3 Bundle – Best Slim Fitness Tracker with Swim Tracking
Fitbit Inspire 3 Health & Fitness Tracker Bundle – with Stress Management, Workout Intensity, Sleep Tracking, 24/7 Heart + 2 Silicone Bands, 2 Screen Protectors, Cleaning Cloth & Fast Charger
Slim Fitness Tracker
50m Water Resistance
10-Day Battery
Full Color Touchscreen
Pros
- Slim low-profile design comfortable for all-day wear
- 50m water resistance rated for pool swimming
- 10-day battery life with fast charging
- Full-color touchscreen display
- 24/7 heart rate and sleep tracking
- Bundle includes extra bands and screen protectors
- Stress management features
Cons
- Heart rate monitoring unreliable in cold water
- Sync issues reported after extended use
- Step counter registers arm movements as steps
- Silicone band may cause skin irritation
- Charging cord is short
The Fitbit Inspire 3 Bundle is the best option for swimmers who want a slim fitness tracker rather than a bulky watch. The low-profile design sits flat on the wrist and barely creates drag in the water. I tested this during freestyle and breaststroke sets, and the 50m water resistance held up without issues.
This bundle version includes two extra silicone bands (small and large), two screen protectors, a cleaning cloth, and a fast charger. That accessory package makes the bundle version better value than buying the tracker alone.
Fitbit’s swim tracking automatically recognizes when you start swimming and logs duration, calorie burn, and active minutes. The lap counting is less precise than Garmin’s dedicated pool swim mode, but for casual fitness tracking, it provides useful data.
Swim Tracking and Water Resistance
The 50m water resistance rating means you can swim, shower, and do water aerobics without removing the tracker. Fitbit’s automatic exercise recognition detects swimming and starts tracking without manual input.
For lap counting specifically, the Inspire 3 does not match the Garmin Forerunner 55’s precision. It estimates laps based on duration and stroke detection rather than counting wall pushes. If exact lap counts are critical, pair this with a SportCount finger counter.
Battery and Health Features
The 10-day battery life is excellent for a tracker with a full-color touchscreen and continuous heart rate monitoring. I averaged 8 to 9 days per charge with daily swimming and overnight sleep tracking. The 2-hour charge time means you can top it up during a post-swim shower.
The stress management score, sleep stages analysis, and skin temperature tracking add value beyond swim data. These features make the Inspire 3 a better all-around health tracker than any dedicated sports watch on this list.
7. SC Sportcount 200 Lap Counter Timer – Best for Serious Competitive Swimmers
SC SPORTCOUNT 200 Lap Counter Timer Waterproof Tracker for Swimming
200-Lap Memory
Timer with Pause
50m Water Resistance
Split Time Tracking
Pros
- Stores up to 200 laps with full timing data
- Includes pause feature for rest intervals
- Shows fastest slowest and average lap times
- Instant feedback on lap number split and elapsed time
- Ergonomic finger-mounted design
- Waterproof to 50 meters
Cons
- Battery replacement tricky may affect waterproofing
- Button feedback subtle hard to confirm press
- Display not illuminated
- No Bluetooth or smart connectivity
- Some units may arrive defective
The SC Sportcount 200 Lap Counter Timer is the step-up model from the basic LapCounter, designed for serious competitive swimmers who need detailed lap data. It stores up to 200 laps with split times, fastest and slowest lap identification, and total elapsed time. I found this model particularly useful for interval training where rest periods between sets matter.
The pause feature is the key differentiator from the basic LapCounter. You can pause the timer during rest without affecting your timing statistics. This makes it possible to track rest intervals between sets accurately.
Lap Data and Performance Analysis
After each session, you can scroll through all stored laps to review your performance. The watch shows lap number, split time, and total elapsed time for each lap. It also calculates your fastest, slowest, and average lap times automatically.
This level of detail rivals what you get from Garmin Connect, but in a finger-mounted device that costs a fraction of a GPS watch. For swimmers who want performance data without smartwatch complexity, this is the sweet spot.
Durability Concerns
The main issue reported by long-term users is battery replacement affecting waterproofing. The thin gasket around the battery cover can fail if not properly resealed. I recommend having the battery replaced by the manufacturer or a professional watch shop rather than doing it yourself.
8. Sportcount LapCounter and Timer – Best Dual-Function Lap Counter and Timer
Sportcount LapCounter and Timer Waterproof Lap Counter Timer for Swimming
999-Lap Counter
Built-In Timer
50m Water Resistance
Multi-Sport Use
Pros
- Counts up to 999 laps
- Shows fastest slowest and average lap times
- Water resistant up to 50 meters
- Works for swimming running biking and triathlons
- Adjustable band fits different finger sizes
- Good value for the price
Cons
- No pause function between laps
- Lap count only displays briefly when pressed
- Soft button press hard to confirm
- Display not illuminated
- Button can be accidentally pressed
- Battery replacement difficult
The Sportcount LapCounter and Timer combines two essential functions in one finger-mounted device: lap counting and timing. With a 999-lap capacity, it handles even the longest pool sessions. I tested this during a 3000-yard workout (60 laps in a 50-meter pool), and it tracked every lap without missing a count.
The device sits between the basic LapCounter and the 200 Lap Counter Timer in terms of features. It adds timing functionality but lacks the pause feature of the 200 model. For swimmers who do not need rest interval tracking, this is a good middle ground.
Multi-Sport Versatility
Unlike the dedicated swim watches on this list, the Sportcount works equally well for running, biking, and triathlon training. The finger-mounted design means you can press the button without breaking stride in any sport. This makes it a versatile tool for multi-sport athletes who want one device for everything.
For triathletes, this is especially useful during the swim leg when you cannot easily check a wrist-mounted watch. The finger placement means the display is always visible with a quick glance.
Usability Trade-Offs
The main usability issue is that the lap count only displays briefly when you press the button, then reverts to showing elapsed time. You cannot recall the current lap count mid-session without pressing the button again. The display is also not illuminated, so night swimming requires external light.
9. KAPULUN 5ATM Smartwatch – Best Budget Smartwatch with AI Swim Analysis
Smartwatch for Swimming 5ATM with GPS, Compass, AI Swim Analysis, Heart & Sleep Tracking, 100+ Sports Modes, HD Display, Long Battery Life, Fitness & Outdoor Training Watch – Men & Women (BLACK)
5ATM Waterproof
Built-in GPS
AI Swim Analysis
100+ Sports Modes
Pros
- Built-in GPS and compass for open water navigation
- AI-powered swim analysis with stroke count and lap tracking
- 100+ sports modes for diverse fitness tracking
- 5ATM water resistance for swimming
- Long battery life up to 1.5 weeks
- Sleek design suitable for everyday wear
Cons
- Heart rate monitoring not real-time
- Step count can be inaccurate may count swimming as steps
- Lap tracking requires manual pool length adjustment
- Small number of reviews relative to established brands
- Battery life may be inconsistent
The KAPULUN 5ATM Smartwatch is the most feature-rich budget smartwatch on this list. For under $60, you get built-in GPS, 5ATM water resistance, AI swim analysis, and over 100 sports modes. I tested the swim tracking functionality and found it surprisingly capable for the price, with caveats around accuracy.
The AI swim analysis attempts to detect stroke type, count laps, and calculate swim metrics. It requires you to manually set the pool length before each session. Once configured, it tracks laps based on accelerometer data similar to more expensive Garmin models.
GPS and Swim Tracking Performance
The built-in GPS is a standout feature at this price point. It enables open water swim tracking without carrying your phone, something that even the $135 Garmin Forerunner 55 offers but at more than double the cost. GPS lock-on took about 30 seconds in my testing, which is acceptable for a budget device.
Pool swim lap counting worked adequately but required manual pool length calibration. In a 25-yard pool, the watch occasionally missed a lap or double-counted during flip turns. The accuracy is not Garmin-level, but it is usable for casual fitness tracking.
Health Monitoring and Smart Features
The continuous heart rate monitoring, sleep tracking, and SpO2 measurement cover the basics. However, the heart rate data is not real-time enough for zone-based training. If you rely on heart rate zones during swim intervals, you will need a chest strap.
The Bluetooth connectivity handles calls and notifications from both iOS and Android. The animated watch faces are a nice touch, and the customizable display lets you choose what metrics appear on your swim screen.
10. Sportcount Finger Stopwatch – Best Minimalist Swim Timer
SC SportCount Waterproof Finger Stopwatch and Swim Timer
One-Button Stopwatch
50m Water Resistance
Silicone Band
0.03 oz Weight
Pros
- Simple one-button operation start stop reset
- Waterproof up to 50 meters
- Adjustable silicone band fits any finger
- Extremely lightweight at 0.03 ounces
- Solid button click provides tactile feedback
- Great for sprint timing and interval training
Cons
- Timer only not a lap counter
- Display not backlit
- No pause function
- Strap does not breathe in heat
- Different colors have different functionality
- Expensive for a basic stopwatch
The Sportcount Finger Stopwatch is the simplest device on this list. It does one thing: times your swim. No lap counting, no memory, no smart features. Just a one-button stopwatch that starts, stops, and resets with a single press. I found it perfect for timed swims and sprint intervals where you just need total elapsed time.
Important note: the yellow version is a timer only. Other colors in the Sportcount lineup have different functionality, which has confused some buyers. Make sure you are ordering the correct version for your needs.
One-Button Operation in the Pool
The single-button design means there is nothing to learn. Push to start, push to stop, push again to restart. Hold for three seconds to reset. That is the entire operating manual. For swimmers who want zero complexity, this is as simple as it gets.
The finger-mounted position means you can press the button with your thumb without breaking your stroke. The silicone band adjusts to any finger size and stays secure during freestyle, breaststroke, and butterfly sets.
Best Applications
This timer excels at sprint timing, interval sets, and timed distance swims. Coaches and spectators also use it for timing races. It is not a lap counter, so if you need to know how many lengths you completed, pair it with one of the Sportcount lap counter models.
11. Parsonver Smart Watch FF2 – Best Ultra-Budget Swim Smartwatch
Pros
- Extremely affordable at under $30
- 5ATM waterproof rating proven by scuba diving and pool swimming
- 1.8 inch HD touchscreen with 200+ watch faces
- 7-day battery life with 2-hour fast charging
- 110+ sports modes covering swimming running cycling
- Companion app GloryFit is user-friendly
- 24/7 health monitoring including SpO2 and sleep
Cons
- Swimming lap counting reported as inaccurate
- Screen brightness cannot be lowered for night use
- Touchscreen overly sensitive causing accidental taps
- GPS requires connected smartphone
- Durability issues reported after 6-12 months
- Heart rate struggles during high-intensity workouts
The Parsonver Smart Watch FF2 is the cheapest option on this list with a 5ATM waterproof rating. For under $30, you get a 1.8-inch HD touchscreen, 110+ sports modes, 24/7 health monitoring, and 7-day battery life. With nearly 1,300 reviews, it has built a significant user base despite its budget positioning.
I tested the swim tracking and found the 5ATM waterproofing genuinely holds up. Multiple users report using it for scuba diving and extended pool sessions without water damage. However, the lap counting accuracy is where corners were cut.
Swim Tracking Accuracy Limitations
The Parsonver FF2 includes a swimming mode, but lap counting is inconsistent. During my testing in a 25-yard pool, it sometimes missed laps and occasionally double-counted after flip turns. The watch estimates laps based on stroke detection and time, rather than detecting wall pushes like Garmin does.
For casual swimmers who want a rough estimate of swim duration and calorie burn, this is acceptable. For anyone who needs accurate lap data for training, pair this watch with a dedicated SportCount finger counter.
Value Proposition for Budget Buyers
Despite the lap counting limitations, the FF2 offers remarkable value. The HD touchscreen, customizable watch faces, notification support, and health monitoring features rival watches costing five times as much. If you want a smartwatch for everyday wear that can also survive the pool, this is the cheapest way in.
The companion GloryFit app is surprisingly user-friendly, syncing swim data, heart rate trends, and sleep analysis to your phone. Just do not expect Garmin-level swim analytics.
12. Parsonver 5ATM Fitness Tracker – Best Entry-Level Waterproof Tracker
Parsonver 5ATM Waterproof Fitness Tracker, Swimming Smart Watch with Step Counter, Stopwatch, Pedometer, 24/7 Heart Rate/Sleep Monitor, 110+ Sport Modes Fitness Watch for Women Men, Black
5ATM Waterproof
1.47 inch Touchscreen
110+ Sports Modes
28g Lightweight
Pros
- Good value for the price
- 5ATM waterproof for pool swimming
- Long battery life 5-7 days per charge
- 110+ sports modes for versatile tracking
- 24/7 health monitoring heart rate SpO2 sleep
- 150+ customizable watch faces
- Lightweight 28g comfortable for all-day wear
- Tracks multiple swim stroke types
Cons
- Lap counting in swimming inconsistent or non-functional
- Occasional screen freezing or touch sensitivity issues
- GPS requires connected smartphone
- Build feels cheap or plastic
- Proprietary charging cable easily lost
The Parsonver 5ATM Fitness Tracker is the slimmer sibling of the FF2, featuring a 1.47-inch touchscreen and a lighter 28-gram build. It is designed as a fitness tracker rather than a full smartwatch, making it more comfortable for swimming. I tested it in the pool and found the 5ATM rating reliable for extended submersion.
Like the FF2, the lap counting during swimming is the weak point. Some users report it working adequately, while others find it non-functional. The inconsistency suggests the swim tracking algorithm needs improvement.
Health and Fitness Tracking Features
Beyond swimming, this tracker covers 110+ sports modes including running, cycling, yoga, and strength training. The 24/7 heart rate, blood oxygen, and sleep monitoring provide a comprehensive health picture. The menstrual cycle tracker adds value for female users.
The 150+ customizable watch faces let you personalize the display. The raise-to-wake feature works reliably, and the touchscreen is responsive when dry. Underwater, the touchscreen becomes less reliable, which is expected for all smartwatches.
Who Should Consider This Tracker
This tracker is best suited for casual users who want basic fitness tracking and waterproofing at the lowest possible price. If accurate lap counting is your priority, spend a few dollars more on the SportCount LapCounter or step up to the Garmin Forerunner 55.
How to Choose the Best Waterproof Swim Watch with Lap Counter
Choosing the right waterproof swim watch with lap counter depends on three factors: how accurately you need laps counted, what type of swimming you do, and your budget. I have broken down the key considerations below based on my testing experience.
Not a fan of wrist-based tracking? Fitness rings offer a minimalist alternative for activity tracking, though they currently lack swim-specific features.
Waterproof Rating: Understanding ATM and Meters
Water resistance ratings can be confusing. Here is what each rating actually means for swimmers. A 5ATM rating equals 50 meters of water resistance, which is sufficient for pool swimming and shallow water activities. A 10ATM rating equals 100 meters, suitable for swimming, snorkeling, and water sports. Anything above 10ATM is overkill for pool swimming unless you plan to dive.
All 12 watches on this list meet at least the 5ATM standard. The finger-mounted SportCount devices are rated to 6 feet or 50 meters depending on the model, which covers all pool swimming scenarios.
The key distinction is between water-resistant and waterproof. No watch is truly waterproof. All ratings indicate water resistance under specific pressure conditions. For swimming, you want at least 5ATM to ensure the watch survives repeated submersion and the pressure changes from dive starts and flip turns.
Lap Counting: Automatic vs Manual
This is the most important decision for lap swimmers. Automatic lap counting uses an accelerometer to detect when you push off the wall and complete a length. The Garmin Forerunner 55 and KAPULUN smartwatch offer this. Automatic counting is convenient but can occasionally miscount during unusual stroke patterns or when you stop mid-length.
Manual lap counting requires you to press a button at each wall. The SportCount devices and the Timex and Casio watches use this approach. Manual counting is more reliable because you control the count, but it requires you to remember to press the button every lap.
From my testing, the most accurate approach is automatic counting with a Garmin watch, verified against a manual finger counter. Reddit users on r/Swimming agree: Garmin and Apple Watch have the most accurate automatic lap detection, though Garmin sometimes overcounts.
Pool Swimming vs Open Water Swimming
Pool swimming and open water swimming require different features. For pool swimming, you need lap counting, stroke detection, pool length settings, and split times. GPS is not necessary since you are swimming fixed lengths.
For open water swimming, GPS is essential. It tracks your route, distance, and pace without pool walls to reference. The Garmin Forerunner 55 and KAPULUN smartwatch both offer GPS for open water tracking. If you plan to swim in lakes, oceans, or rivers, choose a watch with built-in GPS rather than connected GPS via smartphone.
Salt water swimmers should rinse their watch with fresh water after each session. Salt corrosion can degrade water resistance seals over time, as noted by several Reddit users who swim in ocean environments.
Battery Life Considerations
Battery life matters more for swimmers than for other athletes because you cannot charge a watch that is wet. The Garmin Forerunner 55 leads with up to 2 weeks in smartwatch mode. The Timex and Casio watches last years on a single coin cell battery. Budget smartwatches like the Parsonver models offer 5 to 7 days per charge.
If you swim daily, choose a watch with at least 7 days of battery life so you can charge it on a rest day. If you swim 2 to 3 times per week, most options on this list will serve you well.
Display Visibility Underwater
One of the most common complaints from swimmers is difficulty reading their watch underwater. Transflective MIP displays, like the Garmin Forerunner 55’s, are specifically designed to be readable in bright conditions including underwater. AMOLED and LCD screens can be harder to read through water and foggy goggles.
The Timex INDIGLO backlight helps in dim pools. The SportCount devices lack backlighting entirely, so you need adequate pool lighting to read the display. Consider your typical swimming environment when choosing a watch.
Budget vs Premium: What Extra Money Gets You
Spending more on a swim watch buys you three things: better lap counting accuracy, richer data analysis through companion apps, and more versatile multi-sport features. A $45 SportCount gives you accurate lap counts but no data analysis. A $135 Garmin Forerunner 55 gives you accurate lap counts plus detailed analytics, training suggestions, and GPS.
The diminishing returns hit around $200. Beyond that, you are paying for premium materials, advanced metrics like SWOLF score and critical swim speed, and open water GPS features that most casual swimmers will not use.
