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

At 31 mm, reference 278274 occupies the intermediate size tier that Rolex introduced to bridge the gap between the 28 mm Lady-Datejust and the 36 mm standard Datejust. White Rolesor — Oystersteel with 18ct white gold bezel — delivers a platinum-adjacent aesthetic at a more accessible price point, and the combination of a fluted white gold bezel with a silver diamond-set dial is particularly cohesive: the fluting's geometric precision echoes the faceted surfaces of the diamonds, creating a visually unified result. The Jubilee bracelet, matching in Rolesor construction, brings additional formality to the ensemble.

This reference is powered by the Calibre 2236, Rolex's current-generation ladies' and mid-size automatic movement incorporating a Syloxi silicon hairspring. The silicon component eliminates the need for lubrication at the lever-pallet interface and provides enhanced resistance to magnetic fields that would compromise traditional alloy hairsprings. A 55-hour power reserve and Superlative Chronometer certification round out a technically complete specification for a watch of this size category.

The 278274 has found a clear market among buyers who prefer the 31 mm format for its versatility — large enough to wear as a solo piece on the wrist, small enough to layer without overwhelming. The silver-on-white-gold palette has broad cross-market appeal, and the diamond dial ensures that secondary market interest remains strong across buyer demographics. Complete examples in excellent condition are consistently sought after in the pre-owned space.
