Welcome to the forum. That's an Omega DeVille. Worth about $20, but since you're new, I'll offer you $40 :-D Is it quartz or Automatic? Here is one being offered for about $375 (quartz), but not as clean as yours. Not sure its worth that much, so I would say a few hundred dollars if yours is automatic. http://www.ebay.com/itm/Mens-Omega-...es_Watches_MensWatches_GL&hash=item338bc47179Purchases made through these links may earn this site a commission from the eBay Partner Network
