Watch unfit for a serious sports quelquonque activitée

And this for two reasons:

First accounts rebour, this watch offers two countdown that takes over all their super turn for the split, this is the concern that after five repeat it to stop. I think that my first shows a concern, but not tell me it's normal record suddenly I count the repetitions to think to revive the practice countdown ... :)

Second, the backlight illuminates the watch two seconds and even if you press a button (for example to set an alarm clock when we are in the dark), and anything the watch off. Suffice to say that it is a calamity.

In short I am extremely disappointed
