Rolex Datejust 31 Everose Gold — Silver Diamond Dial | Ref. 278275

Reference 278275 represents the Datejust 31 in its most refined Everose Gold expression — Rolex's proprietary 18-carat rose gold alloy, formulated in-house to resist fading and maintain its warm blush tone indefinitely. The fluted bezel, historically used to wind the movement on earlier Rolexes, has evolved into a signature aesthetic element that catches light from every angle. On this reference, the silver dial is set with diamond hour markers, creating a brilliant contrast against the warm gold case that defines feminine luxury horology at its most considered.

Powering the 278275 is Calibre 2236, Rolex's dedicated ladies' movement featuring the Syloxi hairspring — a silicon component developed entirely within the Rolex manufacture. This proprietary spring offers exceptional resistance to magnetic fields and temperature variation, delivering a 55-hour power reserve with enhanced chronometric precision. The 31mm Everose Gold case pairs with an Oyster bracelet in matching Everose, the iconic three-link construction fitted with the Crownclasp for security and a Rolex-signed folding clasp.

The 278275 occupies a compelling position in the ladies' Datejust range — the 31mm case offers a slightly more assertive presence than the 28, while the all-gold construction in Everose rather than yellow or white gold gives it a distinctly contemporary warmth. Collectors drawn to Rolex's in-house material innovations and the pairing of precious metals with diamond appointments will find this reference especially compelling. It wears well across contexts, from formal occasions to daily use, and retains desirability as a flagship expression of the mid-size Datejust.
