Just returned from Australia, and was given my fathers omega watch, have had it serviced and a new strap, the jewellers supplied me with numbers from the inside of back.Was looking for information on age and would welcome your comments. I can recall dad wearing it when I was a teenager, which would be mid 1960's, but no knowing how long he had before. Omega Seamaster Details: 14389-9-csp Movement: 268 Thanking you in anticipation.
