I've seen a lot of beautiful Omega watches from the 1950s on Ebay. Some of them go for between $200 and $400 and would work wonderfully as a nice leather strap watch to wear for dressier occasions, as opposed to my stainless steel Bulova that I wear everyday. Would any of you watch aficionados strongly advise against purchasing a fifty year old Omega at this price? What is likely to be wrong with a fifty year old watch? Can these possible problems be fixed, and at about what cost? Thank you for your help.
