A 1971 Deep Sea. The bezel appears to be that of a typical B model as I haven't seen my example model with the what appears to be a pepsi bezel. It is indeed a deep sea bezel and correct age. Perhaps a swap sometime or maybe was fitted with it originally? I have seen a B model with the typical plain bezel though. The movement shot shows the Valjoux 7733 markings as well. Recently serviced and working beautifully.
Case Serial No.
