Rolex Datejust 31 Yellow Rolesor — Dark Grey Diamond Dial with Domed Diamond Bezel | Ref. 278343

Reference 278343 presents the Datejust 31 in a configuration that layers precious materials with considerable confidence: a domed diamond bezel, a dark grey dial set with diamond hour markers, and the yellow Rolesor case combining 18ct yellow gold with Oystersteel. The domed diamond bezel — a rounded profile set with a full ring of brilliant-cut diamonds — is architecturally distinct from both the flat-profile diamond bezel and the traditional fluted gold bezel, giving the case a softer, more three-dimensional silhouette. Against this, the dark grey diamond dial creates a deliberately moody contrast, the deep charcoal surface making the diamond indices appear to float in shadow.

Calibre 2236 powers the watch — Rolex's purpose-built 31 mm manufacture movement with a Syloxi silicon hairspring, 55-hour power reserve, and Instantaneous date change. The movement sits within the Oystersteel and 18ct yellow gold case, which delivers 100 metres of water resistance through Rolex's Oyster case construction and Twinlock crown. The Jubilee bracelet in Rolesor materials completes the specification, its five-piece links bridging the polished and brushed finish of the case in matching two-tone construction.

Dark grey dials have emerged as one of the more sought-after configurations across the modern Datejust range, appealing to buyers who find traditional white and silver dials too conventional but seek something more wearable than the deliberately bold green or champagne variants. Paired with a domed diamond bezel and yellow Rolesor, this 278343 configuration is a strong all-round choice — feminine without being overtly delicate, jewellery-rich without sacrificing daily wearability.
