Rolex Datejust 31 Everose Rolesor — Mother-of-Pearl Diamond Dial | Ref. 278341RBR

Introduced at Baselworld 2019, the Datejust 31 in Everose Rolesor marks a defining chapter in the model's contemporary evolution. The case unites Rolex's proprietary 904L Oystersteel with 18K Everose gold — an alloy exclusive to Rolex that retains its warm rose hue over decades without fading. Twenty-four brilliant-cut diamonds encircle the bezel, each stone's copper-rose setting amplifying the warmth of the Everose metal to striking effect against the cool steel flanks of the case.

The dial is a mother-of-pearl surface set with diamond hour markers — a combination that maximises luminous play across different lighting environments. Natural nacre shifts between cream, blush, and silver depending on the incidence of light, while the diamond indices add structured sparkle. A dark rhodium Roman numeral at six o'clock provides an unexpected focal accent, characteristic of Rolex's willingness to layer visual complexity within a disciplined layout. The Cyclops magnifier over the date aperture is ground into the sapphire crystal, maintaining the clean profile of the 31 mm case.

The Calibre 2236 — one of the most significant technical evolutions in the Datejust 31 family — powers this reference. Its Syloxi silicon hairspring is impervious to magnetic fields and requires no lubrication, delivering approximately 55 hours of power reserve. A variable-inertia balance wheel allows micro-precision adjustment, while the instantaneous date change and stop-seconds function complete the practical specification. The five-link Jubilee bracelet in Everose Rolesor, fastened by the concealed Crownclasp, integrates with the case to present a coherent, jewellery-grade composition.
