Rolex Datejust 31 Yellow Rolesor — Silver Diamond Dial, Fluted Bezel | Ref. 278273

Reference 278273 presents the Datejust 31 in its most classically composed Rolesor configuration — yellow gold and Oystersteel, fluted bezel, and a silver dial set with diamond hour markers. This combination has anchored the Datejust's identity across multiple generations: the warmth of yellow gold counterpoised against the durability of steel, the fluted bezel's refractive geometry framing a dial where diamond indices provide understated brilliance without ostentation.

The Calibre 2236, Rolex's dedicated manufacture movement for the 31 mm and ladies' Datejust family, powers this reference. Featuring a Syloxi silicon hairspring — the material's immunity to magnetism and thermal fluctuation providing a meaningful advantage over traditional alloy hairsprings — the 2236 achieves a 55-hour power reserve alongside the COSC-certified precision standard. The 31 mm Oyster case in Yellow Rolesor is finished to Rolex's established standard of alternating polished and satin-brushed surfaces, while the fluted bezel in yellow gold adds the characteristic vertical-ridge motif that has been part of the Datejust's visual vocabulary since its earliest years. The silver dial, set with four-claw diamond hour markers, maintains the dial's readability while elevating its material register.

The 278273 in Yellow Rolesor with fluted bezel and diamond indices sits at a sweet spot for the Datejust collector: accessible enough in comparison to full-gold references, yet sufficiently adorned to register as a genuine luxury timepiece. It appeals equally to first-time buyers entering the Rolex secondary market and to experienced collectors who value the Datejust's unbroken heritage and consistent resale depth.
