SIGNED ROLEX, OYSTER PERPETUAL, SUBMARINER, REF. 1680, CASE NO. 3'715'764, CIRCA 1974

Introduced in the late 1960s, the reference 1680 was the first Submariner to feature a date indicator as well as the cyclops magnifier. Distinguished by its red Submariner printing to the dial, the “Red Sub” as it is known to collectors has become a cult classic.
