I am an amateur swimmer and the watch totally meets my athletic needs. It counts very well the total meters of my training - missing only a few exercises - and displays other useful stats such as SWOLF. Plus it totally fits my hand. I am also very satisfied with its other functionalities as well. (steps count, sleeping and stress monitoring, heart BPM measuring e.t.c).

After 2 years, the frame rotted and the strap came off. I contacted Garmin and they told me that it cannot be repaired.

Using two satellite systems, GPS and Galileo, it accurately tracks the position. I tested it on a track of a few meters. In a 25-meter pool without GPS, it occasionally deviated.

I have it here for 1.5 years and my personal opinion is that the device is great for its price. I mainly use it to measure distances in the pool and it accurately measures the meters without losing or adding more than I have done. If that happens, it's my fault. At first, until I realized how it actually measures, it could add 50-100 meters each time. Its battery lasts for 2-3 workouts maximum (with GPS enabled and usage throughout the day) - it could be better but for its price, I consider it okay (I bought it for around 200 euros).

I am a swimming champion and I have been using this for 1 year. There is no inaccuracy in its measurements. Maybe you are not swimming correctly or you are constantly stopping. I have experienced it showing 1050 instead of 1000 meters, which doesn't make any difference as it still accurately records the times. If it shows more meters, you should check your technique.

Negatives: When I sprint, the heart rate is incorrect because the watch moves on my wrist and with the wrist movement, the scanner does not touch my hand. It's not a problem with the watch, it just needed to be noted.
Since I wear it 24/7, my wrist has developed a callus where I wear the watch and it has turned white. I would suggest changing the wrist occasionally.

Positives: Very easy menu, the battery, although advertised for 72 hours, I am almost certain that I charge it every 5 days without any issues (when connected to the phone or when the setting to search for the phone is active, the battery drains).

Unacceptable, the GPS does not measure correctly while running here on the road and shows that I am running in the forest. It takes a long time to lock with the satellite and generally the measurements are wrong at least 40% of the time.
In general, it is comfortable, the battery lasts for several days, and there are many options in the menu.

Bottom of the pool measures more than 15%!!!? more meters, my wife's honor magic that costs 80 euros is not losing at all in the pool much better and in many other aspects, today I took it to the Garmin service, also in the sea whatever, I delete straight lines and it shows that I went to the car and came back for example..whatever and in the measurements I imagine, I gave it today because no matter how much I charge it shows that it has no battery, let me tell you what happened next, with the dealership I spoke on the phone I don't see much Garmin..too bad I had the perfect swim in the pool and of course I'm craving the fenix 5 and 6 at some point I will get it, it also depends on the treatment of the dealership now to see, I have read the best about it but I have experienced the worst, without any interest only to disclaim their responsibilities, they are not interested, unfortunately my ears have experienced these things.

Absolutely inaccurate in pool measurements, the GPS in open water was fine when I tried it. In the pool, it randomly adds 50 meters to each workout. In my usual 2.5km training, there will be an additional 100 to 500 extra meters added each time, as it "sees" extra laps for no reason. So all its statistics are completely useless. After doing the same thing for over 2 months and more than 20 workouts, I took it to the dealership and they told me there is no issue. Given that it is the 3rd swimming tracker I have used and the most expensive one (the first Garmin I tried), I know that other trackers, much more affordable ones, ultimately do a better job. I bought it for an upgrade, but it is simply unacceptable.
