This model also introduced the Cyclops date magnifier to the Submariner line. The 1680 also brought a new luxury marketing philosophy for Rolex as these typical sports watches were never declined in 18K yellow gold or steel and gold cases before. From 1969 to 1974, the "tool-watch", reference 1680 was delivered with Red printing Submariner, aka « Red Sub », different versions of dial are known at least. The present watch is featuring a Mark V dial with feet first designation, red printing for Submariner, open 6.

Preserved in great and attractive condition, with charming patina on the luminous markers that matches the hands. Furthermore, the case is also well preserved with full proportions. The present watch is also fitted with a “PATETED” bracelet, a famous mistake typo. According to scholars, in the 1970s, some Ref. 9315 bracelets with either endlink no. 380 or 280 were fitted with extension clasps reading “pateted” instead of “patented”, a particularly usually founded on watches produced between 1971 and 1973, such as the present watch.
