This watch is nice, but it all depends on the use we want to make. I had chosen for its timing functions with repetition etc ... I needed a sound worthy of the name. And here we touch the big flaw of this watch: the sound signal is inaudible! But really. If you expect him to wake up one morning, forget it! A fortiori, for drives in split, eg., Forget it. by cons if the beep does not serve you, no problem, it is a watch that does.
