Rolex presented this 18k Submariner in 1969. First version came with black “meters first”, “nipple” dial and black bezel. Later meter rating changed to “feet-first” setup. Blue dial-blue bezel version was introduced in 1971. Submariner 1680 was in production until 1979.
Almost all of the blue dialed Submariners have aged to tropical colours, usually different shades of purple and sometimes brown. Blue color in bezel was more age resistant and has usually stayed blue, although somewhat lighter than original.
It is very common that bezel has been changed during service and new bezels can be spotted by looking for color combination. Silver print on blue in early bezels is orignal, gold print on blue is later iteration. Font size was much thicker and lume dot sizes were smaller in original bezels.
