Rolex Datejust 31 White Rolesor — Mother-of-Pearl & Diamond Dial | Ref. 278274

Reference 278274 exemplifies Rolex's mastery of the Rolesor construction — a blend of Oystersteel and 18ct white gold that gives the Datejust 31 its quietly formal character. The white mother-of-pearl dial is set with diamond hour markers, creating a play of iridescence against the fluted white gold bezel, a combination that reads as understated luxury rather than ostentation.

Inside the 31mm Oyster case sits Calibre 2236, Rolex's in-house movement developed specifically for the mid-size and ladies' range. Beating at 28,800 vph, it incorporates the Syloxi silicon hairspring for enhanced magnetic resistance and a power reserve of approximately 55 hours. The case is water-resistant to 100 metres, and the fluted bezel — machined from solid 18ct white gold — adds structural detail while complementing the bracelet's Rolesor centre links.

This reference appeals to collectors who want a daily-wear piece with genuine gemological credentials. Mother-of-pearl dials are inherently natural and no two are identical, making each example subtly unique. The 31mm size occupies a versatile middle ground that suits a wide range of wrists without sacrificing presence, and the white Rolesor palette ensures longevity across changing tastes.
