I've had this watch for a couple of years. I bought it because the watches in the past lacked battery power. I assumed being "solar" powered, this watch would last and last. But it doesn't. It's not reliable. The times it would "die" and lose the time and date became too numerous. I would "charge" it by taking it off and placing it in the summer sun face up, and even then, the next day it would say "recharge." The body is very nice and tough, but the watch started losing its memory and "died" too often after a year or two. I would not buy it again. Better to have a battery that dies and gets replaced than a battery that dies... then comes back... then dies... then comes back. Totally unreliable watch.
