Rolex Datejust Yellow Rolesor — Dark Grey Diamond Roman Six Dial Diamond Bezel | Ref. 278343

This Yellow Rolesor Datejust 31 deploys gem-setting with deliberate restraint: the 18 ct yellow gold domed bezel is pavé-set with brilliant-cut diamonds whose warm scintillation harmonises with the yellow gold hardware throughout, while the Oystersteel monobloc middle case provides the structural durability of Rolex's proprietary 904L alloy. The screw-down Twinlock crown and solid caseback maintain the Oyster architecture's 100-metre waterproofness, ensuring the watch performs reliably beyond its obvious formal credentials.

The dark grey dial is printed with gold Roman numerals at eleven hour positions, but the twelve-o'clock numeral is replaced by nothing — and at six o'clock, eleven brilliant-cut diamonds are micro-pavé set in place of the Roman numeral VI. This asymmetric distribution of gemstones, concentrated at a single position on the dial, produces a visual counterweight to the date aperture at three o'clock and gives the watch an unmistakable identity within the broader Datejust 31 range. The cyclops lens over the sapphire crystal magnifies the date, and the grey lacquer ground ensures optimal contrast with both the applied elements and the diamond VI.

Calibre 2236 — Rolex's manufacture movement optimised for the 31 mm case — drives the timekeeping with a silicon Syloxi hairspring that provides magnetic resistance and extended stability across temperature ranges. The power reserve stands at approximately 55 hours, and the instantaneous date-change mechanism advances the calendar in a fraction of a second at midnight. The yellow Rolesor Jubilee bracelet, combining 904L steel outer links with 18 ct yellow gold centre links, is closed by a concealed folding Crownclasp for a clean, jewellery-grade finish at the wrist.
