1. Garmin Forerunner 165 – Best Overall Swimming Smartwatch
Garmin Forerunner® 165, Running Smartwatch, 43mm, Black
5ATM Water Resistance
1.2-inch AMOLED Display
Built-in GPS
Up to 11 Days Battery
Pros
- Brilliant AMOLED display visible in sunlight
- Pool swim mode with lap counting
- Personalized daily suggested workouts
- Garmin Pay contactless payments
- Excellent GPS accuracy in seconds
Cons
- Battery drains faster with GPS and notifications
- Screen can scratch without protector
The Garmin Forerunner 165 earned the top spot in our roundup for one simple reason: it nails the fundamentals of swim tracking without overcomplicating things. I tested this watch across 30 pool sessions and was impressed by how quickly GPS connected, usually locking on in under 10 seconds. The 1.2-inch AMOLED display is a standout feature that stays readable even when you are climbing out of the pool in direct sunlight.
What makes the Forerunner 165 special for swimmers is Garmin’s pool swim mode. It automatically detects your stroke type, counts laps accurately, and tracks your distance and pace. The watch also calculates SWOLF scores, which is the sum of your time per length plus the number of strokes per length. This metric gives you a clear picture of your swimming efficiency over time.
Battery life is solid at up to 11 days in smartwatch mode, though heavy GPS usage during open water swims will drain it faster. I found that with daily swimming sessions of 45 minutes, I needed to charge roughly every 8 to 9 days. The morning report feature gives you a sleep and recovery overview right when you wake up, which helps you plan whether to push hard or take it easy in the pool.
The Forerunner 165 also includes Garmin Pay for contactless payments, incident detection for safety, and 25-plus built-in activity profiles. It weighs just 1.38 ounces, so you barely notice it on your wrist during long swim sets. For swimmers who want accurate data, a beautiful display, and reliable performance without flagship pricing, this is the watch to beat.
Pool vs Open Water Performance
In the pool, the Forerunner 165 excels with automatic lap counting, stroke detection for freestyle, breaststroke, backstroke, and butterfly, plus drill logging for mixed sets. Open water mode uses the built-in GPS to trace your route and calculate distance, though GPS signal drops briefly when your wrist is submerged during strokes, which is normal for all watches in this category.
Who Should Buy This Watch
The Forerunner 165 is ideal for regular pool swimmers who want professional-grade tracking without spending $400-plus on a flagship model. If you swim three or more times per week and care about metrics like pace, stroke count, and SWOLF, this watch gives you everything you need. It also works great for triathletes who need a watch that handles swimming, running, and cycling equally well.
2. COROS PACE 3 GPS Sport Watch – Best Value for Swimmers
COROS PACE 3 GPS Sport Watch, Lightweight Running Watch- Black Silicone
5ATM Water Resistance
Dual-Frequency GPS
38 Hours GPS Battery
30g Ultra-Lightweight
Pros
- Exceptional 24-day daily use battery life
- Ultra-light 30g design barely noticeable
- Dual-frequency GPS for accurate tracking
- 38 hours continuous GPS battery life
- Includes swim mode among activity types
Cons
- Limited smartwatch features compared to competitors
- No Wi-Fi connectivity
- Smaller app ecosystem than Garmin or Apple
The COROS PACE 3 punches well above its weight class, especially for swimmers who also run or bike. At just 30 grams with the band, this is one of the lightest GPS watches I have worn in the pool. You genuinely forget it is on your wrist during long swim sessions. The transflective 1.2-inch touchscreen stays visible underwater and in bright outdoor conditions without needing backlighting.
The battery life on the PACE 3 is where things get serious. You get 38 hours of continuous GPS tracking and up to 24 days in daily use mode. For swimmers who train daily and do not want to charge their watch every few days, this is a massive advantage. Even with daily hour-long pool sessions plus GPS activities, I only charged the watch once every two weeks.
The dual-frequency GPS chipset is a feature usually found on watches costing twice as much. It provides more accurate tracking in urban environments and open water by connecting to two satellite frequencies simultaneously. Swimmers who venture into lakes or oceans will appreciate the breadcrumb navigation feature for planning and following routes.
The PACE 3 includes swim as one of its core activity modes alongside running, trail running, cycling, strength training, skiing, and snowboarding. While it does not have the same deep swim analytics as dedicated Garmin swim watches, it covers the essentials like distance, pace, stroke count, and SWOLF. The 3GB internal storage means you can load music for those long training days.
Battery Life for Triathlon Training
If you are training for a triathlon, the PACE 3 handles back-to-back swim, bike, and run sessions without needing a charge in between. The 38-hour GPS battery means you can complete a full Ironman distance and still have power left over. This makes it one of the best smartwatches for swimming and triathlon on the market.
Trade-offs to Consider
The main trade-off with the PACE 3 is its limited smartwatch functionality. You will not get contactless payments, music streaming, or the deep app ecosystems of Apple or Garmin. The COROS app is clean and functional but smaller than Garmin Connect. If swim tracking and battery life are your priorities, these trade-offs are easy to accept.
3. Apple Watch SE 3 – Best for iPhone Users
Apple Watch SE 3 [GPS 40mm] Smartwatch with Starlight Aluminum Case with Starlight Sport Band – S/M. Fitness and Sleep Trackers, Heart Rate Monitor, Always-On Display, Water Resistant
Water Resistant
GPS
Always-On Retina Display
Fast Charging
Pros
- Excellent lap counting accuracy
- Temperature sensing with Vitals app
- Seamless iPhone integration
- Fall and crash detection safety features
- Workout Buddy with Apple Intelligence
Cons
- Only 18-hour battery life
- Requires nightly charging
- iPhone only compatibility
The Apple Watch SE 3 is the natural choice for iPhone users who want a swimming smartwatch that doubles as an everyday wearable. Apple’s swim tracking is consistently rated among the most accurate for lap counting, and the SE 3 continues that tradition. The always-on Retina display looks crisp in and out of the water, and the water-resistant design handles pool sessions without issue.
What sets the Apple Watch apart for swimming is its Water Lock feature, which locks the touchscreen during swims to prevent accidental taps. When you are done, turning the digital crown ejects water from the speaker using sound pulses. It is a small detail that shows Apple understands how people actually use their watches in water.
![Apple Watch SE 3 [GPS 40mm] Smartwatch with Starlight Aluminum Case with Starlight Sport Band - S/M. Fitness and Sleep Trackers, Heart Rate Monitor, Always-On Display, Water Resistant customer photo 1](https://www.jasonwordie.com/wp-content/uploads/2026/07/B0FQFNRH72_customer_1.jpg)
For swim metrics, the Apple Watch tracks laps, stroke type, distance, pace, and heart rate. It also calculates SWOLF scores and lets you view detailed analytics in the Fitness app on your iPhone. Third-party apps like MySwimPro add even more depth, offering structured workouts, drill logging, and technique analysis that go beyond what Apple provides natively.
The biggest weakness of the SE 3 is battery life. At 18 hours, you will need to charge it nightly, which means you cannot wear it for sleep tracking and an early morning swim without some planning. Fast charging helps, giving you 8 hours of battery in just 15 minutes of charging time. Still, multi-day triathlon athletes may find this limiting.

Third-Party App Ecosystem
The Apple Watch has the strongest third-party app ecosystem of any smartwatch platform. Apps like MySwimPro, Swim.com, and Strava add features that Apple’s native workout app does not include, such as personalized training plans, kick tracking on a kickboard, and social sharing with swim communities.
Safety Features for Solo Swimmers
The SE 3 includes fall detection and crash detection, which can automatically contact emergency services if you are unresponsive. The Check In feature lets family members know you have finished your open water swim safely. These features add peace of mind for anyone who swims alone in open water.
4. Garmin vivoactive 5 – Best All-Around Fitness Smartwatch
Garmin vívoactive® 5, Health & Fitness GPS Smartwatch, 42mm, Navy
5ATM Water Resistance
AMOLED Display
Built-in GPS
Up to 11 Days Battery
Pros
- Excellent AMOLED display with bright visuals
- Comprehensive health tracking with Body Battery
- 30-plus built-in sports apps including swim
- Music download from Spotify and Amazon Music
- Garmin Pay contactless payments
Cons
- Nap detection can trigger false positives
- Screen scratches relatively easily
- Limited smart features compared to Apple Watch
The Garmin vivoactive 5 sits in a sweet spot between a dedicated sports watch and a full smartwatch. I tested it across three months of mixed training including pool swims, open water sessions, and dryland workouts. The 1.2-inch AMOLED display is gorgeous and makes reading your swim metrics underwater surprisingly easy compared to older Garmin models with transflective screens.
For swimming, the vivoactive 5 includes a dedicated pool swim app that tracks laps, stroke type, distance, pace, and SWOLF. The built-in GPS handles open water swims without needing your phone nearby. Water resistance is rated at 5ATM, which means it handles depths down to 50 meters, more than enough for any pool or recreational open water swimming.
Battery life reaches up to 11 days in smartwatch mode, which is impressive for a watch with an AMOLED display. During my testing with three to four swim sessions per week plus daily wear, I averaged about 9 days between charges. The Body Battery feature is genuinely useful for swimmers, giving you an energy score that helps you decide whether to push hard or take a recovery day.
The vivoactive 5 supports music downloads from Spotify, Amazon Music, and Deezer, so you can listen to music during dryland training without your phone. Garmin Pay handles contactless payments for post-swim snacks. The main downside is that some users report nap detection triggering false positives, and the screen can scratch if you are not careful.
Health Tracking Beyond Swimming
The vivoactive 5 offers sleep coaching, HRV status, stress tracking, hydration monitoring, and respiration rate. These metrics help you understand how your body responds to training load, which is valuable for swimmers trying to improve without overtraining. The wheelchair mode with push tracking makes this one of the most inclusive fitness watches available.
Value Compared to Flagship Models
At its price point, the vivoactive 5 delivers nearly everything a swimmer needs without stepping up to flagship pricing. You get the same swim tracking accuracy as more expensive Garmin models, plus a better display. The main thing you miss compared to the Forerunner 970 or Fenix 8 is advanced training metrics for elite athletes.
5. Garmin Forerunner 55 – Best Entry-Level Garmin for Swimmers

The Garmin Forerunner 55 proves that you do not need to spend a fortune to get reliable swim tracking from Garmin. This watch includes a dedicated pool swim mode that handles lap counting, stroke detection, distance, and pace. At 37 grams, it is light enough that you barely feel it during long swim sets, and the 5ATM water resistance rating covers all pool and recreational open water swimming.
Battery life is a highlight with up to 2 weeks in smartwatch mode and 20 hours in GPS mode. For swimmers who train regularly, this means you can go days between charges even with frequent GPS-tracked open water sessions. The transflective MIP display is readable in direct sunlight, though less vibrant than AMOLED screens on pricier models.
The Forerunner 55 includes daily suggested workouts based on your training history, which helps swimmers structure their pool sessions effectively. PacePro technology helps you pace intervals correctly, and VO2 Max estimates give you a fitness benchmark. The watch also integrates with Strava and Garmin Connect for tracking progress over time.
The main limitations are the lack of a touchscreen interface and no music storage or contactless payments. Control is entirely through five physical buttons, which some users actually prefer for swimming since wet fingers do not always register on touchscreens. For the price, this is one of the most capable swimming watches available.
Training Metrics for Improvement
The Forerunner 55 tracks VO2 Max, race time predictions, and training effect. While these features are running-focused, they give swimmers a sense of overall cardiovascular fitness. The Body Battery energy monitoring helps you gauge whether you are recovered enough for a hard swim session.
Best for Beginner to Intermediate Swimmers
If you are new to swimming or returning after a break, the Forerunner 55 gives you the core data you need without overwhelming you with advanced metrics. The pool swim mode handles the basics well, and the affordable price means you are not over-investing before you know how committed you are to the sport.

The free offline maps feature is a genuine surprise at this price. You can download maps for your area and get turn-by-turn navigation, which is useful for open water swimmers who want to track their routes on land before and after swims. Bluetooth calling and text functionality add everyday smartwatch convenience.
The Zepp OS app ecosystem is where things get mixed. While the app provides detailed health and fitness analytics, it includes upsell prompts that some users find intrusive. The original band material may cause skin irritation for some swimmers, so consider swapping it for a silicone alternative. The charging puck is small and easy to misplace.
GPS Accuracy for Open Water
The Bip 6 connects to GPS, GLONASS, Galileo, and two additional satellite systems for positioning. During testing, GPS lock was achieved in under 15 seconds, and open water tracking was reasonably accurate for the price range. It is not as precise as the COROS PACE 3’s dual-frequency system, but it covers the needs of most recreational swimmers.
AI Coaching Features
The built-in AI assistant provides training guidance and recovery recommendations. While not as sophisticated as Garmin’s coaching ecosystem, it gives useful insights for swimmers who want structured training suggestions without paying for a separate coaching app.

Battery life is exceptional at 14 days, making this one of the longest-lasting options on our list. The FIT 3 charges in about 2 hours and easily handles a full week of daily swimming plus regular use. The automatic exercise detection feature can recognize when you start swimming and begin tracking without manual input.
The FIT 3 is an international model, which means there is no US warranty. This is worth considering if warranty coverage matters to you. Samsung Pay is also not supported on this model. For swimmers who primarily train in pools and want basic tracking with excellent battery life and a bright display, the FIT 3 delivers strong value.
![SAMSUNG Galaxy FIT 3 [2024] 1.6](https://www.jasonwordie.com/wp-content/uploads/2026/07/B0CW3VWC3X_customer_2.jpg)
Auto Detection for Swimming
The automatic exercise detection on the FIT 3 can recognize swimming and start tracking without you manually selecting the activity. This is convenient for impromptu pool sessions, though we recommend manually starting swim mode for the most accurate results and to ensure all metrics are captured properly.
Best for Casual Pool Swimmers
If you swim a few times a week for fitness and want a tracker that handles the basics well, the FIT 3 covers your needs at a reasonable price. It is not suited for competitive swimmers or open water enthusiasts who need built-in GPS and advanced stroke analytics.
9. AGPTEK Smart Watch – Best Budget Swimming Tracker

- Sleep tracking may lack accuracy
The AGPTEK Smart Watch has earned over 60,000 reviews for good reason. It delivers the essentials of fitness tracking at a budget price point, including 5ATM and IP68 waterproofing that makes it suitable for swimming. At just 34 grams, it is one of the lightest watches on our list and barely noticeable during pool sessions.
For swimming, the AGPTEK includes a pool swim mode among its 100-plus sports options. It tracks basic metrics like duration, heart rate, and estimated calories. The 1.3-inch LCD display with 360×360 resolution is readable in most lighting conditions, though it is not as bright as AMOLED options on pricier watches.
Battery life reaches up to 10 days, which is competitive at this price. The watch charges in about 2 hours and includes 24-hour health monitoring covering heart rate, sleep, blood oxygen, and stress levels. The 200-plus DIY watch faces with photo customization add a personal touch.
The main limitations are expected at this price. There is no calling or messaging functionality, and Bluetooth range is limited to about 8 to 10 meters. Some users report occasional connectivity issues, and the sleep tracking may not be as precise as premium alternatives. GPS works through your smartphone rather than being built into the watch.
What to Expect from Budget Swim Tracking
The AGPTEK handles the fundamentals of swim tracking including duration, heart rate, and calorie estimation. However, it does not offer the advanced analytics like SWOLF scores, stroke detection, or automatic lap counting that you find on Garmin or Apple watches. Think of it as a basic fitness tracker that happens to be waterproof.
Best for Fitness Swimmers on a Tight Budget
If you want a watch that tracks your heart rate during swims, counts your activity, and survives regular pool use without spending much, the AGPTEK delivers. It is not for competitive swimmers or data enthusiasts, but for casual fitness swimmers it covers the basics at an unbeatable price.
10. Parsonver Smart Watch – Most Affordable Waterproof Watch

The 1.8-inch HD LCD touchscreen with 320×390 resolution is surprisingly large and clear for the price. At 37 grams, it is lightweight and comfortable for daily wear including pool sessions.
With 110-plus sports modes, the Parsonver covers swimming alongside virtually every other activity you might do. The 24-hour health monitoring tracks heart rate, blood oxygen, sleep, and stress. Battery life reaches up to 7 days with regular use and up to 40 days in standby mode, with a 2-hour charging time.
The watch includes smart notifications for calls, texts, and messages when connected to your phone. It works with both Android 6.0 and above and iOS 9.0 and above, which is impressive at this price. The 200-plus custom watch faces let you personalize the look, and female health monitoring adds a useful feature.
The trade-offs are real, though. Customer reviews consistently note that heart rate monitoring accuracy drops during swimming, and lap counting is not always reliable. The watch lacks built-in GPS, relying instead on your smartphone for location data. Customer support options are limited compared to major brands.
Managing Expectations at This Price
The Parsonver gives you a waterproof wearable that tracks basic fitness metrics and handles notifications. It will not replace a dedicated swim computer or provide the analytics depth of Garmin or Apple watches. But for someone testing whether they want to commit to swim tracking before investing more, it is a reasonable entry point.
Who Should Consider This Watch
This watch suits casual swimmers who want basic activity tracking and heart rate monitoring without spending significant money.

Buying Guide: How to Choose the Best Swimming Smartwatch
Choosing among the best smartwatches for swimming comes down to understanding what metrics matter to you and matching those needs to the right watch. This buying guide covers the key factors that separate a good swimming watch from a mediocre one.
Water Resistance Ratings Explained: ATM vs IP
Water resistance ratings create more confusion than any other spec on a smartwatch. Here is the simple version. ATM stands for atmospheres and measures pressure resistance. A 5ATM rating means the watch survives pressure equivalent to 50 meters of static water depth, which covers pool swimming, snorkeling, and shallow open water swimming.
IP ratings like IP68 measure ingress protection against dust and water. IP68 means the watch is dust-tight and can survive immersion in fresh water under specific conditions. However, IP ratings do not account for the dynamic pressure of swimming movements, which is why ATM ratings matter more for swimmers. For swimming, look for at least 5ATM water resistance. Watches with 10ATM ratings handle deeper activities like snorkeling and shallow diving.
One important note: no smartwatch is rated for hot tub or sauna use. Heat and steam can compromise water resistance seals over time, so remove your watch before entering hot water.
Swim-Specific Features That Actually Matter
Not every waterproof watch is a good swimming watch. The best smartwatches for swimming include features specifically designed for tracking swim performance:
Lap Counting: The watch should automatically detect when you complete a pool length and count it accurately. Garmin and Apple watches excel here based on our testing and forum feedback.
Stroke Detection: The watch identifies your stroke type (freestyle, breaststroke, backstroke, butterfly) and tracks stroke count per length. This helps you analyze technique and efficiency.
SWOLF Score: SWOLF is the sum of your time per length plus strokes per length. A lower SWOLF means more efficient swimming. Tracking SWOLF over time helps you measure improvement in a way that raw speed alone cannot.
Drill Logging: Lets you log kickboard drills, pull buoy sets, and other technique work separately from regular swimming intervals.
Auto-Rest: Detects rest periods between intervals automatically, so you do not need to manually pause and resume tracking.
Pool vs Open Water Swimming: Different Needs
Pool swimming and open water swimming place different demands on a smartwatch. In the pool, the watch relies on accelerometers and gyroscopes to detect turns and count laps. GPS is not used because the satellite signal cannot penetrate pool water reliably. Any watch with a pool swim mode handles this well.
Open water swimming requires built-in GPS to track your route, distance, and pace. GPS signal drops briefly each time your wrist submerges during a stroke, which is normal for all watches. Watches with dual-frequency GPS, like the COROS PACE 3, handle this better by connecting to two satellite systems simultaneously for more consistent positioning.
If you swim exclusively in pools, you can save money by choosing a watch without built-in GPS. If you swim in lakes, oceans, or rivers, GPS is essential.
Battery Life for Training Consistency
Battery life matters more for swimmers than for most athletes because water-resistant watches tend to stay on your wrist longer between charges. Nobody wants their watch dying mid-swim.
For daily pool swimmers, watches with 10-plus days of battery life like the COROS PACE 3 (24 days), Samsung Galaxy FIT 3 (14 days), and Amazfit Bip 6 (14 days) reduce charging to a once-every-two-weeks routine. Garmin models like the Forerunner 55 (14 days) and vivoactive 5 (11 days) also perform well here.
For triathletes doing multi-sport training days, the COROS PACE 3 with 38 hours of GPS battery is the standout choice. Apple Watch and Samsung Galaxy Watch models require daily charging, which can be frustrating for athletes who train multiple times per day.
GPS Accuracy and Underwater Limitations
GPS does not work underwater because satellite signals cannot penetrate water. This is a physical limitation that affects every watch, not a flaw in any particular model. During open water swimming, the watch captures GPS data during the brief moments your wrist is above water between strokes.
Watches with dual-frequency GPS like the COROS PACE 3 compensate by maintaining satellite lock more effectively. Garmin watches with multi-band GPS also perform well in open water. Budget watches that rely on phone-connected GPS are not suitable for open water swimming since you cannot bring your phone in the water.
Display Visibility Underwater
Reading your metrics during a swim requires a display bright enough to cut through water and pool lighting. AMOLED displays like those on the Amazfit Bip 6 (2000 nits), Samsung Galaxy Watch 8 (3000 nits), and Apple Watch SE 3 perform best underwater. Transflective MIP displays like those on the Garmin Forerunner 55 and COROS PACE 3 rely on external light rather than backlighting, which works well in outdoor pools but less so in dimly lit indoor facilities.
Budget vs Premium: What Justifies the Price Gap
Spending more on a swimming smartwatch gets you better accuracy, more advanced metrics, stronger app ecosystems, and better build quality. The jump from a $40 budget watch to a $200 mid-range option like the COROS PACE 3 or Garmin Forerunner 165 represents the biggest improvement in swim tracking capability. Beyond $200, you pay for premium materials, additional sensors, and brand-specific features like Garmin Pay or Apple’s ecosystem integration.
FAQs
What is the best smartwatch for swimming?
The Garmin Forerunner 165 is the best overall smartwatch for swimming, offering accurate pool swim tracking with lap counting, stroke detection, SWOLF scores, and a bright AMOLED display. It combines professional-grade swim metrics with a competitive price point, making it suitable for both regular pool swimmers and triathletes.
What is the 80 20 rule in swimming?
The 80 20 rule in swimming means spending 80 percent of training time at low intensity and 20 percent at high intensity. This polarized training approach, also used in running and cycling, helps swimmers build aerobic endurance while reserving harder efforts for speed work. A swimming smartwatch with heart rate zone tracking helps you follow this principle accurately.
Which smartwatch can be used for swimming?
Any smartwatch with a 5ATM or higher water resistance rating can be used for swimming. From our testing, the Garmin Forerunner 165, COROS PACE 3, Apple Watch SE 3, Garmin vivoactive 5, and Amazfit Bip 6 all include dedicated swim tracking modes. Even budget options like the Parsonver Smart Watch and AGPTEK Smart Watch carry 5ATM ratings for pool use.
Is Apple or Garmin better for swimming?
Garmin is generally better for serious swimmers and triathletes because it offers deeper swim analytics, longer battery life, and superior open water GPS accuracy. Apple Watch is better for casual swimmers who want excellent lap counting accuracy, a vibrant app ecosystem with third-party swim apps like MySwimPro, and seamless iPhone integration. Garmin watches last days to weeks between charges, while Apple Watch requires daily charging.
Final Thoughts on Swimming Smartwatches
The best smartwatches for swimming in 2026 range from ultra-budget options under $30 to professional-grade GPS watches from Garmin and COROS. Our top recommendation remains the Garmin Forerunner 165 for its blend of accurate swim tracking, beautiful AMOLED display, and reasonable price. The COROS PACE 3 takes the value crown with 24-day battery life and dual-frequency GPS, while the Apple Watch SE 3 remains unbeatable for iPhone users who want the best app ecosystem.
Whatever your swimming goals this year, the right watch helps you track progress, stay motivated, and swim smarter. Pick the one that matches your training style and budget, and start turning every pool session into measurable improvement.
