Rolex Datejust Steel — Fluted Bezel Black Index | Ref. 126234

The Datejust 36 in Oystersteel with a fluted bezel and black index dial represents the archetype of the collection — pared to its essentials, classically proportioned, and built to last generations. Reference 126234 occupies a position of particular significance in the modern catalogue: it is the watch that most faithfully honours the original 1945 Datejust design language while incorporating seven decades of incremental engineering refinement. The 36 mm Oyster case, with its characteristic downward-sweeping lugs and finely executed case finishing, is sculpted from a single block of 904L Oystersteel, a corrosion-resistant alloy harder and more lustrous than the 316L steel used by the broader watch industry.

The fluted bezel — one of the most recognisable design signatures in watchmaking — is rendered here in 18 ct white gold, its twenty flutes machined to precise geometric tolerances and polished to a mirror finish. Against the black dial, the white gold bezel creates a high-contrast frame of considerable visual impact. Applied index hour markers in white gold, filled with Chromalight luminescent compound, provide legibility across the full range of lighting conditions, while the Cyclops lens magnifies the date aperture at three o'clock to the familiar 2.5×.

Powering the 126234 is Calibre 3235, Rolex's flagship automatic movement for the Datejust family and a masterpiece of integrated engineering. Its 70-hour power reserve, Chronergy escapement — which improves energy efficiency by 15% over a conventional lever escapement — and Paraflex shock absorbers collectively represent the state of the art in production watchmaking. The Oyster bracelet with Oysterclasp and EasyLink extension completes a watch of enduring, unostentatious excellence.
