Rolex Datejust 31 Yellow Gold — Diamond Bezel, Olive Green Diamond Dial | Ref. 278288RBR

Few dial configurations in the Rolex catalogue command attention with the immediacy of olive green, and on this 31 mm Datejust in 18-karat yellow gold, that richly saturated hue is elevated to remarkable heights. The case — fully realised in yellow gold with a screw-down Twinlock crown and solid case back — frames a bezel set with 46 brilliant-cut diamonds that form a continuous ring of fire around the dial's perimeter. This configuration, known as the diamond-set bezel, transforms the functional bezel architecture of the Datejust into an expression of jewellery-grade luxury without compromising the watch's fundamental precision identity.

The olive green dial deploys diamond hour markers throughout, with eleven brilliant-cut stones set at the VI Roman numeral position in a grouping that creates a focal flourish of deliberate opulence. The cyclops lens over the date display at 3 o'clock — a Rolex hallmark since 1953 — sits beneath a scratch-resistant sapphire crystal, ensuring legibility at a glance regardless of ambient lighting conditions. An 18-karat yellow gold Oyster bracelet with flat three-piece links and a concealed folding Crownclasp secures the watch to the wrist with the robust elegance for which Rolex bracelets are universally recognised.

The movement within is Calibre 2236, Rolex's manufacture calibre developed specifically for the 31 mm ladies' Datejust format. Its silicon Syloxi hairspring — a proprietary innovation — provides exceptional resistance to magnetic interference and thermal fluctuation, while COSC-certified precision guarantees chronometric performance to +/-2 seconds per day. With approximately 55 hours of power reserve and centre seconds with stop-seconds functionality for precise synchronisation, Calibre 2236 represents the full breadth of Rolex's movement engineering expertise applied to the smaller calibre format. The result is a watch of extraordinary completeness.
