this is my memory of first visit to Switzerland in 1988 and I still have it. I would maybe like to add a sub or sea dweller as I mostly collect sport watches, but they cost soooo much now!
Mid 1970s, Rolex Oyster Daytona Cosmograph chronometer (it IS a chronometer), Valjoux 72, manual wind. I owned it for about 30 years. Sadly, long gone, enjoyed by someone else.
Because I am crazy, I swapped the C+I rivet bracelet out for a 7206 rivet bracelet that I think originally came with the watch (as evidenced by end link marks on the lugs and the 26 jewel 1520 movement). Date code on the 7206 bracelet is within a few months of the caseback. What a strange hobby.
