ROLEX. A STAINLESS STEEL AUTOMATIC WRISTWATCH WITH SWEEP CENTRE SECONDS, DATE AND BRACELET

Rolex's first Submariner with date, the reference 1680, was introduced in 1968 with much success. Collectors will make a distinction between a reference 1680 with red writing on the dial and a reference 1680 with all-white writing. Rolex changed to the all-white print dial in 1976⁄77, marking the end of red writing on the Submariner.
