The watch is very easy to use. It has 3 alarms, you can set every day of the week, days, or only on weekends, very convenient. Night vision (indiglo) is excellent. The dial is difficult to remove because it is set back from the edges of the watch, which gives it a very long life. I swim several hours a day in the pool, and the inscriptions are still visible on the watch. Even in contact with water the dial remains highly visible. The screen appears treated so that water runs off it, which avoids surface drop formation. Finally, it is very light and does not feel his bracelet malgrès sweating.
