I know nothing about watches but am interested in getting a 40's or 50's leather banded masonic wrist watch. I see quite a few on ebay for the ~$350 range. I seem to favor the Hamiltons and the Girard Perregauxs does any one have any insight that would help me decide. I have read several of the buying guide threads but I am iterested in understaning is one easier to have worked on or to get parts for when it needs serviced. Is one a superior model? Is there another manufacture that would be superior? Thanks for any insight.
