I use it at work because I could see in other reviews that this watch is resistant to the asser shock. so I specify that I'm a man and that the "bracelet" of this watch is asser big. (Watch wanders about 8 centimeter of my forearm to give you an image), practical dimension: the watch is asser easy (even if the user manual is a bit difficult to understand) there are only two buttons, and to see the time it sufficed DPress the top button. of course they are LED so time is much easier to see in a dark environment (at enough sun to hand over to the shade), and with the "pieces" of metal in place of the Screen you have to put in the face to see the time. So here is! I described what I believe to be things to know if anyone will buy this watch which is very convenient especially for the people who work btp or generally in manual trade. personally I'm very happy! and I think can be offered in my surroundings. mostly seen the price! the colleague we were surprised (by the disign of the watch and when I announce is their price)
