Pre-owned Rolex Sea-Dweller ref 126603 (2026). The Sea-Dweller has always been Rolex’s more serious dive watch. Introduced in 1967, it was designed for saturation diving, featuring a thicker case and a helium escape valve to withstand extreme underwater conditions. For most of its history, it stayed firmly in the tool watch category. No frills, all function. That’s why the 2019 release of the ref 126603 at Baselworld caught so much attention. It was the first time Rolex introduced the Sea-Dweller in two-tone, breaking from decades of all-steel tradition. This 2025 Rolex features Yellow Rolesor pairing stainless steel with yellow gold across the case, bracelet, and bezel, giving the watch a noticeably warmer look without losing its core identity. The 43mm Oyster case is still developed for serious depth, complete with a helium escape valve and 1,220-meter water resistance. The black dial and Cerachrom bezel keep things grounded, while the gold accents make it a bit more versatile. Inside, it runs on Rolex’s caliber 3235 with a 70-hour power reserve.
I picked up Rolex Root Beer from Bob's in 2018 and very happy that I purchased from him.
Customer Service was amazing. They arranged for an extra link and resized the watch for me. Communication was superb . I had great comfort all the way through. I payed for the watch on Friday afternoon Mel time and received the watch Tuesday morning ! Couldn't believe the speed. Watch was perfect and description was 100% spot on.
