this watch runs on movement there is no battery so it can never die. The band is big and it doesn't fit me. Made for someone with large wrists or you can always take off links. call/text me at 7026882952 if your interested. this is 400$ brand new and its only been worn 6 times. this is a very good deal Location: summerlin it's NOT ok to contact this poster with services or other commercial interests nevada
