Rolex 278384rbr-0008 Datejust 31mm Stainless Steel White Gold Diamond White Mother-of-Pearl Dial Watch

Rolex Datejust 31 – Ref. 278384RBR-0008

The Rolex Datejust 31 Ref. 278384RBR-0008 is an exquisite expression of elegance and refined craftsmanship. This ladies’ version of the iconic Datejust merges Rolex’s signature durability with high-jewellery details. Crafted in White Rolesor (a fusion of Oystersteel and 18k white gold), it features a diamond bezel, a luminous mother-of-pearl dial set with diamonds, and the reliable in-house Calibre 2236.

Case Materials

This model houses a 31 mm Oyster case composed of Oystersteel and white gold, known as Rolex’s White Rolesor construction. The bezel is fully set with brilliant diamonds, contributing both sparkle and sophistication. The case is equipped with a screw-down Twinlock crown and Oyster architecture, earning it water resistance up to 100 meters / 330 feet.

Mother-of-Pearl Dial with Diamond Hour Markers

Beneath the scratch-resistant sapphire crystal with a Cyclops magnifier at 3 o’clock lies a white mother-of-pearl dial—a natural material that varies subtly between pieces, meaning no two dials are exactly alike. Diamonds are set in 18k gold settings as hour markers, enhancing both readability and elegance.

Movement Performance

Powering the watch is Rolex’s Calibre 2236, a self-winding mechanical movement built for precision and resilience. It features the Syloxi silicon hairspring and Paraflex shock absorbers. The movement is COSC-certified and further tested by Rolex for accuracy (–2/+2 sec/day after casing). It offers approximately 55 hours of power reserve.

Bracelet Comfort

The 278384RBR-0008 comes mounted on Rolex’s timeless Jubilee bracelet, composed of five-piece links for comfort and flexibility. It includes a concealed folding Crownclasp, which unifies aesthetics and security. The bracelet’s design ensures it sits smoothly and elegantly on the wrist.
