The 1680 uses caliber 1575 throughout its run. ~~This~~ is the ~~date version of the 1570 family, and the rotor on many examples is stamped 1570 rather than 1575, a quirk that can confuse identification. The 1575 was already in service in the~~ Datejust and GMT-Master ~~before the 1680 adopted~~ it~~. The same movement family powered other Rolex sport references of~~ the ~~era, including the 1675 (GMT-Master), 1655 (Explorer II), and 1665 (Sea-Dweller)~~.

The 1680 uses caliber 1575 throughout its run. The practical point is simple: the watch borrows proven Datejust and GMT-Master movement architecture and puts it into the Submariner case.

During the run, Rolex upgraded the 1575 with hacking seconds, which stops the seconds hand when the crown is pulled for time-setting. Early 1680s do not hack. The exact changeover point is not precisely documented.
