1962 Omega Seamaster (believed to be, any other info very welcomed). Inheritance from my late father, used by him for at least 15 years, in which he was a master in the Norwegian merchant fleet. So this watch have been around, in all sorts of conditions. Had it serviced some years ago, however kept all patina on case, hands and dial. The case back is truly marked by all those years on a perlon strap.
One owner (me) Accutron 214. Case back dated 1964. Wore it on our wedding day in 1966, wore at Expo ‘67 in Montreal and got caught in a cloud burst while in the line-up for the Czech pavilion, wore in 1971 when our son was christened, wore it at our 50th wedding anniversary party in 2016. Still looks and runs like new.
