Rolex Datejust 31 Yellow Gold — Champagne Diamond Dial, Fluted Bezel | Ref. 278278

Among the most prestigious configurations available within the Datejust 31 collection, reference 278278 commits entirely to 18-carat yellow gold — case, fluted bezel, President bracelet and clasp — and dresses its dial in two of watchmaking's most refined materials simultaneously: champagne sunray and diamond. The result is a watch whose every surface participates in the generation of light, from the machined channels of the fluted bezel to the ten brilliant-cut diamond hour markers that punctuate the warm golden dial.

The champagne dial, finished with radial brushing emanating from the centre, creates a gradated depth of tone that flatters the diamond markers at each hour position, their stones set to lie flush with the dial surface so no shadow interrupts the luminous field. Calibre 2236 drives the timekeeping function, its Syloxi silicon hairspring delivering COSC-certified chronometric precision across a 55-hour power reserve. The stop-seconds mechanism enables exact time-setting to the second — a practical refinement that belies the watch's jewellery-like appearance and affirms its horological seriousness.

The solid yellow gold President bracelet — reserved exclusively for Day-Date and Datejust references in precious metal — employs semi-circular three-piece links whose convex upper surfaces create a continuous undulating ribbon on the wrist. The concealed Crownclasp closes the bracelet with a satisfying precision, its interior geometry engineered to prevent accidental release. At $29,280, the 278278 represents an investment in a Datejust 31 whose material specification is essentially without compromise — a watch conceived for those who require nothing less.
