Fitness trackers have become wildly popular in the last ten years and knowing which one will be the best for you very much depends on your requirements. Whilst having a lot of choices is a luxury, it can equally be overwhelming. Differentiating between the top brands can be a minefield. Luckily, Superwatches is here to help you navigate that choice.
One requirement that could make or break your decision is waterproofing. Even if you’re not physically underwater, simply running on a treadmill creates sweat and, over time, this can damage your fitness tracker. So we’ve come up with a list of the best waterproof fitness trackers in 2021 which allow you to get caught in the rain, forget you’ve got it on in the shower or swim laps in the pool without worry.
As brands compete for the top spot in the market, wearables are getting better and better. As such, standards are incredibly high, and new developments are fast. Basic trackers used to track calories burned, steps taken and your heart rate (though this last one wasn’t even a given). Later, we saw the introduction of built-in GPS and music storage. Now we seem to be getting used to seeing VO2 max, ECG reading, blood pressure monitoring, stress tracking, recovery time and much more.
But the one thing that ensures your device offers longevity and durability is the waterproofing. Triathletes need trackers that automatically switch sport modes from running to cycling to swimming. Ditto those who go through a heavy lifting session and cool down with a yoga class. Some watches are specially designed for a given sport; you can even get watches for golf!
- GPS model lets you take calls and reply to texts from your wrist
- Measure your blood oxygen with an all-new sensor and app
- Check your heart rhythm with the ECG app
So, here is our list of the 9 best waterproof fitness trackers for 2021:
Apple Watch Series 6
Apple remains firmly at the top spot of popular smartwatches. The latest model, the Series 6, isn’t a massive leap from its predecessor but comes with some advanced fitness features.
It comes in either 40mm or 44mm sizes and has a bigger screen than the Series 5. You can opt for Bluetooth (5.), Wi-Fi or 4G LTE versions.
It offers the latest S6 chip, ECG reading, blood oxygen tracking, fall detection and an always-on display.
The chip means it’s faster than previous versions but doesn’t drain the battery life (though there’s no improvement here, it’s still around 18 hours).
It has a water-resistance rating of 5ATM, which means 50 meters underwater. It’s also ISO standard 22810:2010 certified, meaning you can take it shallow water swimming indoor or outdoor, including the ocean.
- Probably the most feature-rich, advanced smartwatch on the market
- Works faster and charges faster than the Series 5
- Blood oxygen sensor, ECG and accurate onboard GPS
- The most popular, well-known brands. Great support and compatibility.
- As with all Apple models, the battery life isn’t great
- No blood pressure tracking – see why it is important
Garmin Forerunner 945

The Forerunner range is one of the most popular from Garmin. The latest Garmin Forerunner 945 has had a facelift and now offers style and function.
It comes with built-in storage for up to 1000 songs, contactless payment, barometric altimeter and menstrual tracking. As it’s a Garmin, it naturally offers an excellent training mode which provides in-depth data on heat, altitude, acclimation status, aerobic and anaerobic training effects and recovery time.
Weighing in at 50g, you won’t even notice this wearable. Which is impressive considering the punch it packs. You’ll get up to 36 hours between charges if you’re using GPS mode, but less if you’re using the music function.
The Forerunner 945 is expensive, though. So, if you like the sound of all this but it’s not within budget, check out the Forerunner 45 instead.
This is another 5ATM rated watch.

What’s more, it has a Pulse Ox sensor to measure you blood oxygen saturation. If you’re interested in storing music on board, this will cost you a little extra.
As with the others on this list, the waterproof rating is 5ATM.
- Good looking fitness tracker
- Sensors for advanced tracking not commonly seen at this price
- Doesn’t play music without paying extra
Suunto 3 Fitness
The Suunto 3 is a reliable and contemporary tracker. It looks as sleek as it functions. Once you put in your basic data like height and weight and age, it will give you a simple weekly training plan. This is a mix of workouts and rest days. If you put this watch into its Personal Training mode, you can get an overview of your workouts and when your rest days are.
Based on your VO2 Max data and resting heart rate, this tracker will make revisions to your plan to keep your fitness level improving as time goes on. This could be more intensity or putting you on a rest day over the weekend when you can get some more sleep to recover. You’re able to look over your workouts afterwards and scroll through the basics like distance travelled and recovery time needed.
The Suunto 3 is waterproof to 30m so there’s no need to remove it before showering or swimming.
