Rolex Datejust 31 Everose Rolesor — Silver Diamond Dial, 24-Diamond Bezel | Ref. 278341RBR

Reference 278341RBR in Everose Rolesor elevates the Datejust 31 into the realm of high jewellery watchmaking, deploying a factory-set bezel studded with 24 round brilliant-cut diamonds alongside a silver dial whose hour markers are individually set with diamonds selected for matched brilliance. The Everose Rolesor combination — pairing Oystersteel with Rolex's exclusive 18 ct rose gold alloy, formulated to maintain its colour without fading over decades — brings warmth and femininity to an architecture that remains entirely Oyster in its engineering rigour.

The movement within is the Calibre 2236, Rolex's current ladies' manufacture calibre and a technically distinguished watch in its own right. Beating at 28,800 vph with a silicon Syloxi hairspring — a paramagnetic component machined via LIGA lithographic process to micron-level precision — the 2236 offers a 55-hour power reserve and Superlative Chronometer certification. The Syloxi hairspring provides exceptional resistance to magnetic interference and temperature variation, ensuring consistent regulation across real-world wearing conditions.

The 278341RBR sits at the pinnacle of the Datejust 31 range and represents the manufacture's commitment to uncompromising gem-setting quality. The 24-diamond bezel and diamond-set dial make this reference among the most jewellery-intensive in the Datejust family, yet the watch loses nothing of its sporting versatility — the Oystersteel case and Jubilee bracelet ensure durability that matches the decorative ambition. For the collector who demands both horological substance and gem-set brilliance, this reference is without peer in its segment.
