After 3 tests (2500 m and 1000 m 2 times) in pool 25 and 50 m, I am very satisfied. The watch has recognized 4 strokes without error on the 3 sessions. Calculating distances was as perfect; you just mark the corners by making the coullées. At the first use I changed swims every 25 or 50 m, no errors. The watch is forgotten wrist and does not interfere with swimming. The use is very simple (pool size change, start / stop, connection, ...). Pausing / resuming at stops is controlled bya single button, and the consideration given by an acoustic signal. Perfect tool for swimming, taking his time, calculate the number of movements. To my mind, this watch is more for an audience of savvy swimmer: water swims online, marked corners .... However, there is a small gadget for the utility side (not the quality) is to see: for a regular swimmer who knows his training program, a simple chono will do. In conclusion, I am very satisfied with my gadget :)
