Rolex Datejust Everose Rolesor — Mother-of-Pearl Diamond Dial, 46-Diamond Bezel | Ref. 278381RBR

Introduced at Baselworld 2019, the 278381RBR in Everose Rolesor marked a significant expansion of the contemporary Datejust 31 family, combining Oystersteel with 18-karat Everose gold in a warmly luminous two-tone composition complemented by 46 brilliant-cut diamonds pavé-set in the Everose gold bezel. The density of the bezel's gemological investment — nearly double that of many comparable references — creates a virtually continuous band of prismatic light that shifts with every movement of the wrist.

The white mother-of-pearl dial operates as a natural foil to the Everose surround, its organic iridescence cycling through blush, ivory, and pale rose tones that harmonise intimately with the warm metal palette. Diamond hour markers, individually set and inspected, provide the structural rhythm of the dial composition without interrupting its organic fluidity. Calibre 2236, the movement developed specifically for this case class, features Rolex's proprietary silicon Syloxi hairspring — an innovation that effectively eliminates the movement's susceptibility to magnetism while improving positional isochronism — and delivers a generous 55-hour power reserve.

The Everose Rolesor Oyster bracelet, with its alternating steel and gold links machined to sub-millimetre tolerances, transitions seamlessly from the case flanks. The folding Oysterclasp with Easylink 5 mm comfort extension allows discreet fine-adjustment for changes in wrist volume. Water-resistant to 100 metres, the 278381RBR is a reference that addresses the collector who requires gemological splendour without conceding anything of the Oyster's legendary robustness.
