The Rolex Submariner reference 1680 is notable as the first Submariner model to feature a date complication, marking a significant evolution for the line. Introduced in the late 1960s, it bridged the gap between the earlier no-date Submariners and later iterations, offering enhanced functionality while retaining the robust characteristics of the professional tool watch. This reference is distinguished by its single cyclops date magnifier on the crystal, a feature that would become a hallmark of many subsequent Rolex models.

This reference typically features a 40mm steel case, housing the self-winding Caliber 1575 movement. The movement provides a power reserve of approximately 48 hours.
