Second, you did well by coming here and asking the community to assess a watch for you before you pulled the trigger on the purchase. Continue to do that and you won't go wrong.

Last, you may find that the best place to purchase a vintage Omega is right here on the private watch sales forum. This is a community of Omega enthusiasts and collectors and good watches at fair prices come up for sale frequently. Good luck with your search and what a thoughtful gift for your soon to be husband. He's a lucky man.
