We tested these connected sports watches in real situations to evaluate their design and comfort, especially in terms of their size and weight. Next, we judged the quality of their screen in daylight and night. We explored the applications and menu of each watch to check the responsiveness of their interface, but also their intuitiveness. The features were also tested with particular attention to those that are useful during the practice of various sports such as GPS, activity detection and heart rate. The sensors had to be precise, but also that their use did not have too much impact on the autonomy of the watches.

Other models tested
- Garmin vivoactive 5 : We excluded this sports smartwatch from our selection because its plastic design does not make a good impression. Additionally, we got imprecise data, especially regarding altitude and heart rate, and the GPS was quite slow.
- Samsung Galaxy Watch Ultra : We excluded this sports smartwatch from our selection because its heavy, imposing design didn't stick to the skin as well during our tests, skewing some data. In addition, the battery life of around 2 days is much lower than other models and certain applications can only be used if you have a smartphone from the same brand. At such a price, we prefer not to suggest it.
