Rolex Datejust 31 White Rolesor — Silver Index Dial with Domed 24-Diamond Bezel | Ref. 278344RBR

Among the most refined expressions of the Datejust lineage, the 278344RBR presents the iconic 31 mm Oyster case in White Rolesor — Rolex's proprietary marriage of Oystersteel and 18 ct white gold — that strikes a precise equilibrium between sporting durability and jewellery-grade elegance. The domed bezel, pavé-set with 24 brilliant-cut diamonds, encircles the dial in an unbroken halo of scintillating light, transforming a horological instrument into a wearable objet d'art without sacrificing any of the collection's legendary practicality.

The silver dial is purposefully restrained, allowing applied index hour markers to catch the light cleanly and deliver immediate legibility. A scratch-resistant sapphire crystal fitted with a Cyclops lens magnifies the date aperture positioned at three o'clock, a Rolex hallmark that marries utility with visual clarity. Beneath the case, the calibre 2236 — Rolex's self-winding manufacture movement engineered specifically for the 31 mm Lady-Datejust and Datejust 31 family — oscillates at 28,800 vph and provides approximately 55 hours of power reserve, incorporating a Syloxi silicon hairspring for superior resistance to magnetic fields and temperature variation.

The watch is completed by the five-piece link Jubilee bracelet in Oystersteel and 18 ct white gold, secured by the concealed folding Crownclasp — a refined fastening mechanism whose clean profile preserves the bracelet's uninterrupted visual flow. The screw-down Twinlock crown and solid case back guarantee water resistance to 100 metres, ensuring this luminously appointed piece is as capable as it is beautiful. At 31 mm it sits with quiet authority on the wrist, equally at home at a board meeting as at an evening gala.
