Rolex Datejust 31 Yellow Rolesor — Fluted Bezel Champagne Index Dial | Ref. 278273

Yellow Rolesor — Rolex's proprietary pairing of 904L Oystersteel with 18ct yellow gold — has a particular chromatic affinity with the champagne dial: both share an underlying warmth that deepens the overall impression of the watch. In reference 278273, a 31mm Datejust released at Baselworld 2019, this harmony extends to the 18ct yellow gold fluted bezel, whose machine-engraved facets catch and fragment light across their angled planes. The champagne dial's applied index markers in polished gold-coloured metal complete a composition whose tonal coherence is precise and deliberate.

The Calibre 2236 self-winding movement — Rolex's dedicated calibre for the Datejust 31, housing a silicon Syloxi hairspring and regulated to COSC chronometer standards — delivers approximately 55 hours of power reserve and date-change functionality at three o'clock via a rapid-setting mechanism that advances the date without interrupting the timekeeping. The movement's production follows Rolex's fully integrated manufacture process, from casting alloy blanks through to COSC certification testing, ensuring traceability and consistency that no externally supplied movement can replicate.

The Jubilee bracelet in Yellow Rolesor — alternating Oystersteel and 18ct yellow gold five-piece links — recalls the bracelet's origins as a celebration piece for the Datejust's 1945 debut. Here it terminates in a concealed Crownclasp whose flush integration with the surrounding links maintains the visual rhythm of the alternating metals. The combination of fluted bezel, champagne dial, and yellow Rolesor metal pairing produces a watch that reads as a cohesive whole, warm in tone and classical in structure. Water resistance is 100 metres.
