When I reseved the watch firt of all I fix the date and the time ...and when I want to make it work I saw that the watch is not working...I rotate the key but nothing..I don't touched the back side of the watch because I don't want to do worse..so I'd put it back in the box and I call grupon....Please send the watch in work to the following address because it is a gift for my boyfriend Schitco Victor  on Via.Chiodare 13,35031 Abano Terme,Italy
