Your heart rate will be measured underwater by the Garmin Swim 2 device.

Garmin made the announcement today that their watch for tracking water adventures has been updated to its second generation. The Garmin Swim 2 monitors your heart rate while you are swimming underwater, it has a built-in GPS, it comes with compatibility for swimming in open water, and it has many more features.

Keeping up with the ever-growing array of sports watches offered by Garmin is becoming an increasingly challenging endeavour. Garmin Swim is one of the products that hasn’t been updated in a considerable amount of time, however. This timepiece was introduced back in 2014, which seems like a lifetime ago today. That, however, is no longer the case now that Garmin Swim 2 has been made available.

It should come as no surprise that the second version includes several improvements over the first one. This contains built-in GPS, GLONASS, and Galileo, as well as the Garmin Elevate wrist heart rate sensor, which can monitor heart rate even while the wearer is submerged in water.

The watch has a physical size of 44 x 48 x 13 mm, which is larger than the physical size of its predecessor, which was 42 x 42 x 11.4 mm. Even when the screen is completely illuminated by the sun, the always-on, full-colour Garmin Chroma Display technology that is included in Swim 2 makes everything much simpler to read.

The number of functional enhancements is so great that it is virtually impossible to list them all. However, you can get a comparison of Garmin products by clicking on the link provided below. In a nutshell, you now have access to fundamental land activity tracking statistics (step count, move metre, calories, time, stress, Body Battery…), performance assessment (Training Effect, Physio True-up…), as well as certain features pertaining to running and cycling.

In terms of swim monitoring, in addition to everything that its forerunner had to offer, Swim 2 comes with time and space notifications, pacing alerts, and essential swim speed data. All of these features are included in the app. This one gives you an estimate of your speed at the anaerobic threshold. It can serve as a guide for your training, and you can use it to monitor your progress.

The encouragement of swimming in open water is a significant departure. The built-in GPS in Swim 2 makes it possible to track swims in bodies of water such as lakes, seas, or rivers and record information such as radius, pace, stroke count, SWOLF, stroke rate, and stroke distance among other metrics.


Moreover, there is now a greater amount of intelligent functionality than there was previously, which includes support for notifications, social functionality, and other features. The choice between the Garmin Swim and the Garmin Swim 2 should not be a difficult one if you are in the market for a new swim watch.

Having said that, Garmin currently offers a far larger variety of sports watches compared to what they did in 2014. Therefore, choosing between Swim 2 and other products in the line is not as cut and dry as one might think. For example, the Forerunner 945, MARQ, and Fenix 6 series all have much of the functionality that is included in Swim 2, or at the very least, they will receive it very soon. The difference in price, on the other hand, is significant!

When it comes to swimming, the Swim 2 is comparable to the Forerunner 245, which is designed for running. It has a lot of features that are exclusive to one sport, and it also has a few other extras that turn it into a functional fitness tracker.

The only swim-related functions that are currently exclusive to the Garmin Swim 2 and not found on any other Garmin device are those that are stated on the company’s website as follows:

  • Auto Resting (Pool Swim Only)
  • Notifications based on time and distance
  • Warnings for pacing (pool swim only)
  • The necessary swimming speed

The battery life on Garmin sports watches, in general, is satisfactory. In smartwatch mode, the Swim 2 has a battery life of up to 7 days; in GPS and optical heart rate (OHR) mode, it has a battery life of 13 hours; and in pool and OHR mode, it has a battery life of 72 hours.

Starting today, the watch may be purchased on You have the choice between Whitestone and Slate, and the cost of either one will set you back 249.99 dollars.
