I have a Guess watch with the name "Georges Marciano" on the dial face. I know he was one of the founders of that company. Does anyone have a guide as to the value of this watch? Were they common or was it a short run? I got it as a gift back in the 1980s but haven't worn it since.....I can't remember. It runs fine, has a new battery and is in excellent condition with the original leather band. Any help out there?
