Pre-owned Rolex Submariner ref. 126613 (2020) is the current production Yellow Rolesor model, cased in steel and yellow gold, and featuring the updated 41mm Oyster case and the in-house caliber 3235 with a longer 70-hour power reserve. It’s just the latest in a long line of two-tone Submariners, some modern and robust, others more subtle and vintage. This generation launched in 2020, officially introducing the collection to the first 41mm Submariner case. It also swapped the long-trusted caliber 3135 for the upgraded caliber 3235 and introduced cosmetic upgrades, such as less boxy lugs. It’s still waterproof up to 300 meters, so it can still go for a dive in the ocean. It’s just more reliable and refined for an even better wrist-wearing experience. Shop Rolex Submariner Collection
