The watch looks to be from the 1960s...the case looks a lot like those used for the 855 model. but the centre disc of the dial that says reveil is more modern. The 1960s dials had an equilateral triangle on the alarm disc as a marker (and usually no text). The marker on this watch is an elongated triangle and says reveil like watched from the 1990s onwards. Its a nice looking watch but certainly not untouched.
