Rolex Lady-Datejust 31 31 mm 278383RBRDGRDVIJ Steel/Yellow Gold/Diamonds Grey

The Rolex Lady-Datejust 31 reference 278383RBRDGRDVIJ is one of the most expressive iterations of an icon that has defined feminine luxury watchmaking for decades. Measuring 31 mm in diameter, this reference occupies the sweet spot between the classic 28 mm Lady-Datejust and the larger 36 mm Datejust, offering a wrist presence that feels modern and substantial without overwhelming a slender wrist. The Oyster case is rendered in a two-tone combination of Oystersteel — Rolex's proprietary corrosion-resistant steel alloy — and warm 18k yellow gold, a pairing the brand calls Rolesor, which has been a hallmark of aspirational elegance since its introduction.

The dial of reference 278383RBRDGRDVIJ is a dark grey surface appointed with Roman numerals, a choice that lends the watch a classical yet contemporary personality. Grey dials have surged in desirability among collectors for their remarkable versatility: they read as sophisticated neutrals under bright light while taking on a richer, almost slate-like depth in dim conditions. The Roman numerals anchor the design in horological tradition and pair beautifully with the yellow gold applied indices and hands that catch the light with every movement of the wrist.

The bezel of this Lady-Datejust 31 is set with diamonds, elevating the reference into genuine jewellery-watch territory. The diamond-set bezel frames the dial like a constellation, adding scintillation that catches light from every angle. This combination — grey dial, yellow gold case elements, and diamond bezel — creates a layered visual hierarchy that rewards close inspection while remaining immediately striking at a glance, making 278383RBRDGRDVIJ one of the most photogenic references in the current Lady-Datejust collection.

Powering the watch is a Rolex automatic movement, engineered to the brand's famously exacting tolerances. Rolex automatic calibers are certified chronometers, meaning they meet the precision standards set by the COSC as well as Rolex's own even stricter in-house criteria. With a water resistance of 100 meters (330 feet) courtesy of the Oyster case's screw-down crown and case back, this Lady-Datejust 31 is built to be worn every day without anxiety, whether that means a morning swim, a rain-soaked commute, or an evening gala. The Jubilee bracelet — a five-piece link design created by Rolex in 1945 specifically to debut alongside the original Datejust — completes the look with exceptional comfort and a supple drape on the wrist.
