40mm. Dial color: Black. Glass: Plexiglas. Watertightness: 20 ATM. Rolex deployable clasp. From the liquidation of an inheritance, property of a private collector, Spain. In correct running condition. No Other Rolex Submariner Has Featured Red Submariner Text Since Rolex stopped producing the Red Submariner 1680 in the 1970s, every subsequent rendition of the stainless steel Submariner has been fitted with an entirely black and white dial (with the exception of the all-green “Hulk” Submariner). This design choice makes it incredibly easy to spot one of these rare, Red Submariner watches, as the name and color instantly stand out against the monochromatic color profile of the rest of the watch. The Reference 1680 Was The First Submariner To Offer A Date Function. When Rolex unveiled the ref. 1680 (the earliest examples being Red Submariner watches) it was the first Submariner to be equipped with the date window at 3 o’clock and the magnifying Cyclops lens affixed to the surface of its acrylic crystal. Due to the added date feature, a different movement from the one used in the no-date Subs was needed. The Submariner Date ref. 1680 ran on the Caliber 1575, which was based on the existing Caliber 1570 but with an added date function. With that in mind, it is important to note that the calibers inside the ref. 1680 are stamped “1570” (as are all other Cal. 1575 movements).
