I acquired a 1960s Omega Seamaster 300 watch a while ago through the family and I've only just realised it's could be quite valuable. The watch has been in storage since c. 1975 and mechanically is hardly worn. The watch is the Big Triangle version ref. 165024-64 and appears to be authentic having checked various vintage watch web sites. Unfortunately, the minute hand has been poorly repaired with a luminous paint which no longer matches, an after market stainless bracelet has been fitted and I have no documents or box. I welcome advice on the following: 1. What is the watch potentially worth to sell in its current condition? 2. Is it worth having the minute hand restored to increase the value of the watch? 3. Is it worth replacing the bracelet to increase the value of the watch? What straps / bracelets would have been fitted to the watch originally?
