Best Swimming Watches Available Now – 2020

Swimming Watches

Lots of fitness watches claim to be suitable for swimmers, but very few live up to this claim. This is because some ‘swimming watches’ are vulnerable to water damage. Also, whilst most swimming watches can record open water swims, few can record lane swims.

Having said that, there are some great swimming watches out there. And, if you want to improve your performance, it’s worth investing in one. For more in-depth information of what makes a swimming watch different, read our guide.

Advantages and benefits of swimming watches
The Advantages of Swimming Watches

What are the benefits of swimming watches?

If you’re new to fitness tracking, you might be wondering what the point of a swimming watch is. Well, a good one can:

  • Track lengths – When swimming in a pool, it’s easy to lose count of how many lengths you’ve swum, so length tracking is handy.
  • Length-by-length data – The ability to differentiate lap data, for example, which lap you swam the fastest.
  • Technique monitoring – Some of the more sophisticated watches will analyse your swimming technique. It will tell you if your stroke rate is too fast, slow, or optimum.
  • Share your data – You can share and compare your fitness data with others. Swimming is a lone sport, so sharing your data can be motivational. It can also help you to build a supportive community.

So, whether you’re a doggy paddler or the next Michael Phelps, here are 4 swimming watches that will help you reach your goals.

1. Garmin Swim 2

Garmin Swim

Specifically designed for swimming and open water activities, the Garmin Swim is an excellent choice. Track your swim with GPS and measure your heart rate, even underwater. It comes with all the usual activity tracking features of a Garmin watch and is fit for many other sports activities.

For the pool, it can record your distance, pace and stroke efficiency. It can also help with your swimming drills. The Garmin Swim 2 is designed for swimming and is lightweight, luminous and easy to work in the water. It could give you real-time pacing alerts while swimming. You can read our full review of the Garmin Swim 2 here.

GPS mode allows up to 13 hours combined with heart rate measuring. Otherwise, it could last for up to 72 hours in pool mode and 72 hours with standard mode.

Pros:

  • Designed for swimming
  • Lightweight – Only 36g
  • 5 ATM
  • Sunlight visible

Cons:

  • Slightly more expensive than other models at $249
  • Not necessarily a diving watch
  • No touch functions

2. Samsung Gear Fit 2 (Pro)

This is a versatile fitness tracker that is great for measuring swims. It is reliably water-resistant so there’s little chance of water damage (as long as you stick to surface swimming).

This watch can track lane swims as well as open water swims. It’s also compatible with Speedo Swim; an App that offers training plans, community support and swimming tips! One of the best things is that you can see your data in real-time (i.e. laps swam), which can be really motivating. *Update – November 2020 – The Speedo On app may no longer by compatible with this watch, please ensure you thoroughly research the apps available before making your purchase.

Pros:

  • Water-resistant up to 50 meters (though it is marketed for surface swimming and light snorkelling only)
  • Smartphone notifications
  • Built-in GPS – so great for Triathlons
  • Slim and discreet design
  • 4gb storage for music

Cons:

  • Battery life is 1-2 days – some comparable devices last up to 5 days.
  • It struggles to detect stair climbing (may not be an issue if you are only using it for swimming)

3. Garmin Forerunner 935/945

The Garmin Forerunner 935 (or the newer 945) is an activity tracker that does it all. Though not specifically a swimming watch, many people prefer it to the Garmin Swim watch because it can do so much more. For example, it can track running, walking, hiking, and swimming, to name but a few sports.

If you enjoy open swimming, you’ll really appreciate this watch because the in-built GPS and compass are useful for navigation.  

Like many other swimming watches, it struggles to capture your heart rate whilst swimming. However, you can purchase a Garmin accessory which will accurately measure your heart rate whilst swimming.

Pros:

  • It’s a multisport activity tracker
  • Water-resistant up to 165 feet – but cannot be used for scuba diving or snorkelling
  • It provides advanced output data for swimming, running, and cycling – great for triathletes!

Cons :

  • There may be some accuracy issues when measuring pool lengths – though these issues seem to have been resolved since the last update
  • A masculine design so probably not the best fitness tracker for women

4. Fitbit Charge 3 and 4

Fitbit Charge 3

If you’re looking for a swimming watch from the Fitbit range, the Charge 3 or the newer Charge 4 could be the one. This is a great watch that can track all sorts of swimming data.

The only downside to the Charge 3 is that it doesn’t show your data in real-time. You’ll have to dry off before you can see how many lengths you’ve swum. If you can live without this feature, the 3 is great value for money. The Charge 4 does offer real-time tracking and has GPS.

Pros :

  • It’s very affordable, especially compared to other swimming watches
  • It’s a multisport activity tracker (though not as sophisticated as the Garmin Forerunner 945)
  • Offers detailed swim technique insights via the Fitbit App
  • 7+ days battery life
  • Slim design

Cons:

  • It’s not an open water swimming watch
  • It doesn’t offer real-time updates, which is disappointing to some

5. Suunto Spartan Trainer Wrist HR

$289 on Amazon.com

Suunto devices are extremely accurate fitness trackers targeted towards athletes. If you’re a serious swimmer, check out the Suunto Spartan Trainer.

This device is excellent for tracking swims, cycles, runs, hikes, etc. It’s very lightweight, so it won’t slow you down. It’s argued that the design is a little masculine but this purely down to taste. It is also resistant to 100 meters, which is unique for a swimming watch! You can read our full review of the Suunto Spartan here.

Pros :

  • Precision is second to none
  • Inbuilt GPS so it can track a variety of activities
  • Good for pool and open water swimming
  • Extremely lightweight so it won’t get in the way of your front crawl

Cons :

  • 10 hours of battery life when in training mode. If battery life is your priority, choose the Fitbit Charge 3 instead.

Choosing a swimming watch

So, there you have four of the best swimming watches for 2020. On balance, the Fitbit Charge 4 is probably the favourite. Not only does it offer great value for money, but it also encourages you to focus and improve. The Suunto Spartan Trainer is precise and the Garmin Swim 2 is an excellent choice for the pros.

As always, know what features you are looking for before you make a purchase. To help you decide, you could read our guide on how to find a great watch for swimming and a few more swimming watch alternatives.

Although the swimming watches mentioned in this article are water-resistant, they are not waterproof. None of these would be suitable for diving. If you want a watch that’s suitable for swimming and diving, look for a dedicated scuba diving watch instead.

    Are you sure that Samsung Gear Fit 2 Pro does track openwater swiming? I have got this device and it’s GPS does not work in swiming mode, in order to track openwater swiming.

    I spoke with Fitbit support and they stated the Charge 4 DOES track laps in real time, while the Charge 3 does not.

    I am an open water swimmer and have a fitbit versa 2 which does not do what it says it does and keeps failing. Fed up i have decided to give to my daughter and get myself a garmin forerunner, even though I prefer the look of the fitbit.

      Hi Emma, that’s unfortunate. Maybe contact Fitbit as it may be an issue with that particular watch rather than the model. However, the Garmin Forerunner is an excellent choice of watch for tracking

      Hi Neil, thank you for your comment. There certainly seems to be a lot of issues with the Speedo On app in general at the moment. We will add a note in this article to make people aware of the changes.

      We hope you enjoy our content, please be sure to follow us on social media for our latest updates.

    Fitbit Charge 4 is for swimming but the GPS does not work for open water swimming. Only tracks laps for pool swimming. Only found this out when I went to set up for swimming. Took it back and got a refund. Really misleading.
