Rolex Datejust 31 Everose Gold — Diamond-Paved Butterfly Dial | Ref. 278245

Among the most jewellery-forward expressions of the Datejust 31, reference 278245 pairs an 18ct Everose gold case with a dial whose entire surface is paved with diamonds arranged in a butterfly motif. Everose is Rolex's proprietary rose gold alloy — formulated with a small percentage of platinum to resist the fading common in standard 18ct rose gold — giving the case a warmth that endures over decades.

Calibre 2236 powers this reference, a movement purpose-built for the 28–34mm segment of Rolex's collection. Its Syloxi hairspring, made from silicon, offers superior resistance to temperature variation and magnetic fields compared to traditional Nivarox alloys. The domed bezel frames the extraordinary dial, which requires painstaking hand-setting of each brilliant-cut diamond by Rolex's in-house gem-setting workshop.

Reference 278245 occupies the intersection of haute joaillerie and sports-watch durability — it is pressure-resistant to 100 metres despite its gem-set complexity. For collectors seeking a Rolex that functions equally as a precious object and a wearable timepiece, few references make the case more convincingly. Its combination of proprietary gold alloy and pavé craftsmanship positions it as a strong long-term hold in the secondary market.
