this is not my watch but it is identical
i have a different metal link style band on it, and from what i gather by this picture my face is in better condition.
the site i got that picture from was selling the watch for $2999. i just would like to know a realistic value on the watch as far as any other information someone can give me. i got this watch when i was 12 ( i am now 19) as a gift and had no idea it was worth anything until the other night i was bored and googled it.
