This bi-metal Rolex Sea-Dweller reference 126603 is a bold, highly capable professional dive watch that combines extreme performance with unmistakable Rolex presence. Crafted from stainless steel and 18ct yellow gold, the substantial 43mm Oyster case is paired with a black Cerachrom bezel and matching black dial, accented by rich gold detailing. This Rolesor configuration brings a distinctive luxury edge to one of Rolex’s most technically serious tool watches, while retaining the rugged character that defines the Sea-Dweller line. Produced in 2021 and presented in immaculate condition, this example offers commanding wrist presence and exceptional visual impact.
Powering the watch is the Rolex Calibre 3235 automatic movement, a current-generation calibre engineered entirely in-house. Featuring the Chronergy escapement, improved efficiency, and a power reserve of approximately 70 hours, the Calibre 3235 is renowned for its precision, robustness, and long-term reliability. Designed to meet the demands of professional saturation diving, the Sea-Dweller also benefits from a helium escape valve and an impressive water resistance rating of 1,220 metres, underscoring its true tool-watch credentials.
From an appreciation and investment perspective, Rolesor Sea-Dweller models occupy a unique position within the Rolex sports range, offering precious metal content in a reference produced in comparatively lower volumes. The 126603 continues to attract strong interest from collectors seeking standout modern Rolex sports watches with long-term relevance. Supplied boxed and certified with original full set paperwork and a 12-month WLC warranty, this Sea-Dweller represents a compelling opportunity to acquire a highly capable and increasingly desirable pre-owned Rolex.
