Rolex Datejust 31 Yellow Rolesor — Dark Grey Diamond Roman Six Dial, Diamond Bezel | Ref. 278383RBR

The Datejust 31 in Yellow Rolesor exemplifies Rolex's mastery of tonal contrast: a 31 mm case that combines the cool resilience of Oystersteel with the warmth of 18-karat yellow gold, crowned by a bezel pavé-set with round brilliant diamonds whose fire dances against the metal beneath. The dark grey dial introduces a decidedly modern sensibility, its depth recalling slate and shadow, while eleven diamond hour markers — with the Roman numeral VI distinguished by a further row of brilliant-cut stones — lend the dial a sculptural, textured quality that rewards close inspection.

At the heart of the watch beats Rolex Calibre 2236, manufactured entirely in-house at the Manufacture in Geneva. This movement, developed specifically for Rolex's mid-size and ladies' timepieces, features a Syloxi hairspring — a silicon component machined by Rolex itself — that renders the oscillator impervious to magnetic fields and temperature fluctuations while delivering a power reserve of approximately 55 hours. The date aperture at three o'clock is magnified by a Cyclops lens integrated into the scratch-resistant sapphire crystal, providing instant, effortless readability.

The Yellow Rolesor Jubilee bracelet — with its semi-circular three-piece links alternating steel and gold — provides a supple, elegant fit on the wrist. The concealed folding Crownclasp ensures security without interrupting the bracelet's clean aesthetic. Waterproof to 100 metres via the screw-down Twinlock crown, this Datejust 31 represents the Baselworld 2019 generation: a thoroughly contemporary interpretation of an icon that first defined the dressed sports watch category in 1945.
