Rolex Datejust Gold — Rose Diamond Dial | Ref. 278245

The Datejust 31 in full 18 ct gold occupies an elevated stratum within the Rolex catalogue, blending the historic proportions of the 31 mm case with the unequivocal luxury statement of a monometallic gold construction. Reference 278245 in rose gold is among the most refined iterations of this size class, its warm Everose alloy — Rolex's proprietary 18 ct gold formulation resistant to fading — providing a coherent material palette from case to bracelet.

Powering this reference is Calibre 2236, Rolex's manufacture movement developed specifically for the smaller case diameters in the Datejust family. The 2236 incorporates the Syloxi silicon hairspring, a component that provides superior resistance to thermal variation and magnetic fields compared to traditional metallic springs. The rose diamond dial — set with brilliant-cut diamonds creating a radiant, light-scattering surface — is a tour de force of Rolex's gem-setting discipline. Each stone is evaluated for cut, colour, and clarity before setting, ensuring a uniform visual result across the dial.

A fully gold Datejust 31 with a diamond-set dial is unambiguously a jewellery-grade timepiece, one that appeals to collectors who value wearable artisanship as much as horological mechanics. The Everose gold case resists the surface tarnishing that can affect lesser alloys over time, preserving its appearance across decades of wear. For those seeking a gift piece or a self-purchase at the intersection of watchmaking and high jewellery, this reference is a compelling choice.
