Pre-owned Rolex Sea-Dweller ref. 126600 (2024) was a significant upgrade for the series. Released in 2017 to celebrate the Sea-Dweller’s 50th anniversary, it introduced a larger 43mm Oyster case and, for the first time in the model’s history, a Cyclops lens over the date. Although these changes marked a departure from previous generations, they also made the watch more practical for everyday use without compromising the rugged character that has always defined the Sea-Dweller. Rolex also paid tribute to the model’s earliest days by reviving the red “Sea-Dweller” text on the dial, a subtle tribute of sorts to the collectible Single Red Sea-Dweller references of the late 1960s. Beneath the modern styling is still everything enthusiasts expect from the collection, including 1,220 meters of water resistance, a helium escape valve, and the robust Oyster case construction.
