In the fall of 2020, Rolex announced a brand new Submariner collection, complete with all the metal options rather than the traditional once-a-year drop of a new case material. Of course, included in this new lineup of Rolex dive watches was the two-tone Submariner ref. 126613, again available in either blue and black.
The most obvious difference between the current-production two-tone Submariner versus the previous ones is the case size. The Submariner ref. 126613 has a 41mm case along with slightly thinner and more refined lugs (although its actual case diameter when measured is just slightly under the official 41mm that is listed on its spec sheet). This subtle, yet significant case redesign signals a return to the classic proportions of the five-digit Submariners before the arrival of the “Super Case” variants.
Another important update accompanying the latest two-tone Submariner 126613 is the new-generation Caliber 3235 automatic movement that powers the watch. Built around Rolex’s proprietary Chronergy escapement and boasting a slew of patents, the new series of Rolex movements offer users an improved power reserve of approximately 70 hours (compared to the 48-hour reserve of previous references).
Other key design details of the TT Submariner remain the same, which is to say 18k yellow gold and steel cases and bracelets, unidirectional rotating Cerachrom bezels marked to 60 minutes, and a date window at 3 o’clock on the dial magnified by a Cyclops lens. Like the versions that came before it, the latest two-tone Submariner is water-resistant to 1,000 feet (300 meters). Moreover, the hour markers and Mercedes-style hands are generously coated with Chromalight lume for optimal legibility in the dark.
