Launched around 1967, reference 1680 was the first Submariner model to be fitted with a date function. The model was most typically cased in stainless steel. Early examples displayed a "meters first" depth rating, with the "Submariner" script printed in red, hence the name "Red Submariner".

The present example is fitted with a Mark 5 dial, displaying "feet first" as opposed to "meters first". The 6 is "open", and the red "Submariner" text is directly printed on the dial. All these attributes are correct for the 3.184 million serial number.

Of note is the "Pateted" inscription inside the extendable link. Research shows that Rolex had released a batch of bracelets with this typo, which in a twist of fate, have become collectible today.

Consigned by the son of its original owner, this watch is as "complete" as one can be. It is accompanied by its original punched guarantee stating the watch was sold on 6 December 1974 in Spain. Furthermore, the owner has dutifully serviced the watch three times, having kept the service guarantee in 1993, 2002 and 2006. It is also offered with its original product literature, wallet and fitted presentation box.
