I was wondering if you could help me in identifying a solid gold vintage Bulova I purchased by accident on eBay. The watch appears to be a Director or Tuxedo model with the 7AK movement. One concern I have is the lack of any kind of serial number or Bulova engraving on the outside of the case back, which I thought these models all had. Are these cases thick enough to grind/polish these engravings out? The seller gurantees the watch is 100% authentic, so I think I can return it if it's been tempered with.
Any feedback would be much appreciated.
