Rolex Datejust 31 White Rolesor — Silver Diamond Dial, Fluted Bezel | Ref. 278274

Introduced as part of Rolex's landmark 2021 Datejust 31 refresh, the reference 278274 in White Rolesor represents a significant escalation in the mid-size Datejust's specification. The 31 mm case pairs Oystersteel with 18ct white gold, and the fluted white gold bezel — a design that harks back to the original 1945 Datejust — serves a dual purpose: it is both an aesthetic emblem of the model's heritage and a structural reinforcement of the case architecture. Diamond hour markers set into the silver dial create a constellation-like distribution of light that shifts character with every angle of the wrist.

The beating heart of this reference is the Calibre 2236, a self-winding manufacture movement that replaced the earlier 2235 across the 31 mm Datejust range. The 2236 incorporates the Syloxi hairspring, crafted from silicon — a material chosen for its insensitivity to magnetic fields, its negligible thermal expansion coefficient, and its long-term stability. The twinlock double waterproofness system on the screw-down crown, combined with the Oyster case's hermetically sealed construction, ensures protection to 100 metres depth, underpinning the watch's credentials as a true Oyster professional.

Matched with an Oystersteel Oyster bracelet featuring flat three-piece links and a concealed folding Oysterclasp, the 278274 achieves an elegant balance between jewelled luxury and the understated robustness that distinguishes genuine Rolex craftsmanship from mere ornamentation. With approximately 55 hours of power reserve, the watch comfortably survives a weekend without winding — a practical virtue that complements its considerable aesthetic allure. For collectors seeking a refined mid-size companion with impeccable pedigree, this White Rolesor Datejust 31 is an exemplary choice.
