Ergonomic, easy to use, it is an effective watch whatever the training session with its large storage capacity; race, it saves time every kilometer course: the button is easily accessible and accompanied by a beep; it also wakes me every morning; this is the second time I buy the same product; on the first, I changed once bracelet (ordered from decathlon) and it's the second battery change I had a little problem sealing (but still works)
