Best for iPhone UsersApple Watch Series 11
Pros & Cons
Why We Picked It
Apple's flagship smartwatch, the Series 11, has a WR50 rating, meaning it's water-resistant to 164 feet and suitable for shallow-water activities, such as swimming in a pool or the ocean close to shore. It's also safe to wear in the shower or a hot tub. Its Workout app offers separate tracking options for pool and open-water swimming, as well as a multisport mode for triathletes. Plus, the Series 11 has an IP6X certification, meaning it's totally dustproof and immune to sand damage, making it ideal for beach wear. This model also includes Apple's excellent Depth app and a water-temperature sensor, features previously limited to the Ultra series. The Series 11's big, bright screen makes it very easy to see your real-time depth, even in murky water conditions. 5G connectivity will allow you to leave your phone behind on beach day and still benefit from speedy performance.
Who It's For
Apple fans: The Apple Watch Series 11 requires an iPhone 11 or later running iOS 26 or higher, so it's not an option if you use Android, but it is an excellent option for those seeking a smartwatch that tracks swimming and keeps you connected outside the water.
App lovers: Apple still offers the most wearable apps of any ecosystem. The Depth app, in particular, is handy to have for a day at the beach. Note that the Series 11 is not safe for scuba diving, waterskiing, or other activities involving high-velocity water or deep submersion.

Best for Automatic Swim TrackingFitbit Charge 6
Pros & Cons
Why We Picked It
Fitbit's most popular fitness tracker, the Charge 6, is water-resistant to 164 feet and safe to wear in the rain or in the pool. The Exercise app offers a swim-tracking option, and the device features a Water Lock setting that prevents the screen from activating when you're in the water. The Water Lock automatically turns on when you start a swim in the Exercise app, or you can enable it at any time via the Quick Settings menu. Additionally, Fitbit's SmartTrack feature automatically recognizes and records certain types of workouts, including swimming.
Who It's For
Casual swimmers: The Charge 6 is an excellent investment for anyone looking to improve their health without spending a bundle, making it a perfect fit. Note that Fitbit cautions against regularly wearing the Charge 6 in the shower, as exposure to soap and conditioner may reduce its water resistance. It's not safe for the hot tub or sauna, either. Regular beachgoers and outdoor adventurers should consider a more rugged device because the Charge 6 has no dust protection rating.
People with fitness goals beyond swimming: With 40 exercise profiles for workout tracking, the ability to send your heart rate to gym equipment, and multiple other tools for monitoring your activity and health, the Fitbit Charge 6 is the best fitness tracker for most people.

Who It’s For
Women who prioritize style: The Garmin Lily 2 is a top pick for women, especially given its size and swagger, but it’s one of the best fitness trackers for anyone with small wrists or a penchant for style.

Why We Picked It
The Galaxy Watch FE is an affordable Android smartwatch that features 5ATM and IP68 ratings, making it waterproof to 164 feet and dust-, dirt-, and sand-resistant. It also meets the MIL-STD-810H standard, so it should survive extreme temperatures and other environmental stressors such as vibration and shock.

Why We Picked It
Apple's rugged Watch Ultra 3 has a WR100 rating, which means it can withstand depths of up to 328 feet, and it's durable enough for high-speed water sports like kitesurfing, wakeboarding, and jet skiing. It also meets the EN13319 international standard for dive computers and gauges and is safe for recreational scuba diving down to 130 feet. The Ultra 3 has MIL-STD 810H certification, meaning it can withstand high altitudes, extreme temperatures, freezing/thawing, blowing sand, and other environmental stressors, including vibrations and shocks.

Buying Guide: The Best Waterproof Fitness Trackers for 2026
What to Look For in a Waterproof Fitness Tracker
You don't need to settle for merely waterproof. The same seals that keep water from ruining the electronics in swim-friendly fitness trackers also protect them from water pressure. Most waterproof fitness trackers are rated for a certain depth. Typically, these devices have a 5ATM rating, which means you can plunge them up to 164 feet underwater. Some have a lesser 3ATM rating, meaning they are submersible up to 98 feet. However, a 5ATM rating does not make a watch safe for scuba diving. Samsung states that devices certified to 5ATM can only withstand depths of up to 164 feet for 10 minutes.
Consider what you want your tracker to do. Are you more interested in viewing your data during or after a workout? If you want to keep an eye on your laps while you're in the pool, you should look for a tracker with a bright screen. You should also make sure it's capable of responding to your strokes underwater.
Another thing to keep in mind is how swim-centric you want your device to be. If swimming is your primary source of exercise, verify that your tracker supports multiple underwater activities.
The Apple Watch Ultra 3 is one of the most water-friendly models on this list, with a WR100 rating, which means it can withstand depths of up to 328 feet—twice that of the Series 11. The Ultra 3 is ideal for high-speed water sports such as kitesurfing, wakeboarding, and jet skiing. The Ultra 3 is also certified to the EN13319 international standard for dive computers and gauges, meaning it's safe for recreational scuba diving descents down to 130 feet.
(Credit: Fitbit)What Are the Best Smartwatches for Swimmers?
The line between fitness trackers and smartwatches is increasingly blurry. These days, many of the big smartwatches feature heart rate monitors and GPS, just like fitness trackers. Add a waterproof build, and many become suitable for use in the pool and ocean.
Recommended by Our Editors
An additional benefit is that they tend to be more stylish than their fitness-focused counterparts. After you towel off, you can easily switch your swim-friendly silicone strap for a classier metal or leather band.
Most of the models on this list are safe for swimming in a pool or the ocean, as well as for use in the shower or a hot tub. However, be sure to check our reviews for details on water resistance. With the exception of the Ultra series, Apple Watches are not suitable for scuba diving, water skiing, or other high-velocity water sports.
(Credit: Fitbit)Which Fitbits Are Waterproof?
The good news is that all Fitbit trackers and smartwatches are water-resistant; they can withstand rain, sweat, and faucet pressure. Some older Fitbits were not safe for swimming, but all current models in Fitbit's lineup are. That includes the Charge 6, Inspire 3, Sense 2, Versa 4, and the kid-friendly Ace LTE and Ace 3. You can wear them in the pool, and they can track swimming stats like lap counts, pace, and total duration.
Regardless of brand, be sure to remove your wearable after it gets wet and wait for it and your wrist to completely dry before putting it back on. Most waterproof wearables are safe to wear in the shower, but be cautious when using soap, as it can cause damage to certain materials.
