Rolex Datejust 31 Everose Rolesor — Dark Rhodium Diamond Roman VI Dial with Fluted Bezel | Ref. 278271

Introduced at Baselworld 2019, this Datejust 31 in Everose Rolesor represents Rolex at its most sartorially inventive. The 31mm case in the distinctive combination of 904L Oystersteel and 18-karat Everose gold is crowned by an Everose gold fluted bezel — its classically engineered facets lending the watch an heirloom quality that transcends seasonal taste. The dial, rendered in deep dark rhodium, carries Roman numerals with a single diamond set at the 6 o'clock position in place of the conventional numeral, a subtle jewellery detail that rewards close attention.

Calibre 2236 provides the movement architecture, notable for its silicon Syloxi hairspring — produced in-house at Rolex's Bienne facilities using LIGA deep-etch lithographic processes — which delivers superior magnetic resistance and thermal stability compared to traditional alloy hairsprings. Chronometer certification to +2/-2 seconds per day by the Swiss Official Chronometer Testing Institute (COSC) ensures that this technically innovative movement meets the precise standards expected of a Superlative Chronometer designation. Approximately 55 hours of power reserve sustain the display over extended periods of non-wear.

The Everose Rolesor Jubilee bracelet, with its distinctive semi-circular five-piece links alternating steel and Everose gold, provides a secure and aesthetically coherent accompaniment to the mixed-metal case. The concealed folding Crownclasp and screw-down Twinlock crown complete the waterproofing architecture to 100 metres. This reference rewards the wearer who seeks a Datejust that speaks to both tradition and the refined jewellery sensibilities that define contemporary haute horlogerie.
