My 3 Omega watches:
Top Row: far left: My favorite Omega watch, i don't know the name of this watch, but it is Serial # 9XX of 1000 watches made for the Seoul-Calgary Olympics back in about '87 or so.
Top Row: far right: omega Speedmaster, 2 tone, circa maybe '87 or so
lower row; middle: Omega that I generally wear to work, so the others don't get beat up at work. The top two are probably off on dates and so forth as I haven't worn either one for a while. The Seoul-Calgary Commertative Omega is battery operated and probably needs a battery. The speedmaster is a wind, and the lower one is a battery.
