Rolex Datejust Yellow Gold — Champagne Concentric Circle Index Dial | Ref. 178248

Crafted entirely in 18 ct yellow gold, reference 178248 represents the Datejust 31 in its most classically opulent expression — a full precious-metal construction that situates this watch firmly within the tradition of grande horlogerie dress timepieces. The domed bezel, polished to a mirror surface, traces the organic curvature of the case flanks and adds a sculptural quality that distinguishes it from the flat or gem-set alternatives in the collection. The screw-down Twinlock crown, also in yellow gold, maintains the Oyster case's 100-metre water resistance without compromising the formal aesthetic.

The champagne dial is executed with a concentric circle guilloché texture, a decorative technique borrowed from the world of high jewellery and pocket-watch making. Each circular groove refracts incident light differently depending on the viewing angle, producing a subtle animated quality that plain lacquer dials cannot replicate. Applied index hour markers sit on the outermost ring of the dial, their vertical facets picking up the yellow gold of the case. The date window at three o'clock is magnified by the Cyclops lens in the scratch-resistant sapphire crystal.

The movement is Calibre 2235, the predecessor to the current 2236 and the established calibre for 31 mm Datejust references produced during the period of this reference number. It features a Parachrom hairspring in niobium-zirconium alloy, resistant to magnetic fields and insensitive to temperature variations, within a self-winding architecture delivering approximately 48 hours of power reserve. The 18 ct yellow gold President bracelet, with its characteristic semi-circular three-piece links, is secured by a concealed folding crown clasp, completing a wholly coherent precious-metal package.
