Rolex Datejust 31 Yellow Gold — Dark Grey Diamond Six Dial, Diamond Bezel

A full 18ct yellow gold Datejust 31 set with a factory diamond bezel and a dark grey dial featuring diamond hour markers at the six o'clock position represents one of the more dramatically appointed configurations in the Datejust 31 family. The contrast between the deep grey dial and the warm lustre of yellow gold creates a composition of considerable visual tension — sophisticated without resorting to obvious ostentation. Each diamond in the bezel is individually selected for cut, colour, and clarity before setting, in keeping with Rolex's exacting gem-setting standards.

The movement within is Calibre 2235, Rolex's self-winding manufacture calibre developed for the 31mm case diameter. Its rotor geometry and mainspring architecture are tailored to the spatial constraints of the smaller case while preserving the chronometric performance for which Rolex movements are certified. The solid yellow gold Oyster case provides 100 metres of water resistance through the Twinlock crown system, and the integrated Jubilee or President bracelet in matching gold completes the ensemble.

Full yellow gold Datejust 31s with diamond bezels occupy the upper tier of the reference's value spectrum, appealing most strongly to collectors and buyers seeking a fully integrated precious-metal dress watch. The dark grey dial variant is a less common configuration, lending it a degree of rarity relative to white, silver, or champagne alternatives. Provenance, box and papers, and dial originality are the primary determinants of value at auction and in the secondary market.
