Rolex Datejust 36 Stainless Steel - Yellow Gold - Domed / Black Roman / Oyster Ref. 126203-0056

The Rolex Datejust 36 126203-0056 debuted in 2026 as a Yellow Rolesor configuration within the Datejust collection, combining a 36 mm Oyster case with a bright black dial, new-style Roman numerals, a domed bezel, and an Oyster bracelet. Its Oyster case measures 36 mm in diameter and follows the established Datejust architecture with a monobloc middle case, screw-down case back, and Twinlock screw-down winding crown. The case is executed in Yellow Rolesor, combining Oystersteel and yellow gold, while the bezel is the domed type. A scratch-resistant sapphire crystal with Cyclops lens covers the dial side, and water resistance is rated to 100 metres. The dial is executed in bright black with a sunray finish and fitted with the updated Roman numeral hour markers used for this family of references. The display remains the standard Datejust arrangement of central hours, minutes, and seconds with a date window at 3 o’clock. In this configuration, the domed bezel keeps the emphasis on the dial and the two-tone construction rather than on the bezel itself. Inside is Rolex calibre 3235, a self-winding mechanical movement with central hours, minutes, and seconds, instantaneous date with rapid setting, and stop-seconds for precise time setting. It offers a power reserve of approximately 70 hours and is equipped with a blue Parachrom hairspring and Paraflex shock absorbers. The watch is fitted with an Oyster bracelet in Yellow Rolesor with three-piece solid links. It is secured by an Oysterclasp folding clasp and incorporates the Easylink comfort extension system, allowing approximately 5 mm of on-the-wrist adjustment.
