Rolex Datejust 31 Everose Rolesor — Purple Diamond Dial | Ref. 178341

Reference 178341 is a 31 mm Datejust rendered in Everose Rolesor — the two-tone combination of Oystersteel and 18 ct Everose gold — with a 24-diamond bezel surrounding a purple diamond dial set with Roman numerals at the six o'clock position. This configuration sits at the intersection of sport and high jewellery, the two-tone case providing versatility while the purple dial makes an unmistakably bold statement. The 31 mm format is Rolex's mid-size offering, widely favored by wearers who prefer a feminine scale without sacrificing the readability of the full Datejust layout.

The 178341 houses Calibre 2236, a manufacture movement developed specifically for Rolex's mid-size and ladies' references. The calibre incorporates the Syloxi hairspring, a silicon component engineered for superior isochronism across temperature fluctuations and immunity to magnetic interference. Power reserve stands at 55 hours from a single mainspring barrel. The Jubilee bracelet — a five-link design dating to the original 1945 Datejust — pairs with the Everose Rolesor case to deliver a balanced, dressy appearance that transitions seamlessly from professional settings to evening wear.

Collectors approaching the 31 mm Datejust market will find that diamond-dial references in Rolesor configurations occupy a sweet spot: they carry the full prestige of the Datejust lineage while remaining more accessible than equivalent precious-metal examples. The purple diamond variant is a relatively uncommon dial choice, making it appealing to those who prioritise individuality within the Rolex ecosystem. Pre-owned examples in strong condition with clean service histories are sought after by buyers who want jewellery-grade presentation without the premium of a precious-metal case.
