my dad was a certified/degreed watchmaker who could repair/work on rail roaders' pocket watches, then after rail roaders were allowed to carry Bulova Accutrons, he went to school to learn how to service/repair them too.
Until the late 1980's or so, nearly every large town & small towns had a watch maker & jewelry shop or two.. then after the cheap electric wrist watches became prevalent, those fine shops died out. Now good jewelry shops are confined to mainly cities, small & large, and watch makers are a dying breed.
We collect Hamilton 992B pocket watches... but I have one fine old Elgin pocket watch that was owned by a friend's wife's grandfather... Sandy is only I her early 70's.. I have hope that either her only child or one of his two sons will change their mind & want it... it saddens me that they have no interest in it. Old Gus traded it in on another watch, back in the mid 1970's. I think on an Accutron.. shortly before he died. Dad's ticket showed he'd cleaned & oiled it... & some repair, as it only cost $2.50... I thin it was to replace the crystal..
