Rolex Datejust 31 Yellow Rolesor — Champagne Diamond Dial | Ref. 178243

Rolesor — Rolex's patented combination of Oystersteel and 18 ct gold on a single bracelet — has been a signature of the Datejust since Hans Wilsdorf first deployed the technique in 1933. Reference 178243, the 31 mm Datejust in yellow Rolesor configuration, carries this tradition forward with characteristic assurance, its alternating steel and gold Oyster bracelet links creating a dynamic visual interplay that is simultaneously dressy and robust.

The champagne diamond dial elevates the reference into jewellery-watch territory: a warm champagne-toned ground — evoking the lustre of fine cognac or aged amber — is adorned with twelve diamond hour markers individually assessed and set by Rolex's in-house gem-setters. The domed bezel, executed in polished 18 ct yellow gold, frames the dial with a clean arc that draws the eye inward toward the diamond constellation. The Datejust's hallmark date window at three o'clock is magnified by Rolex's patented Cyclops lens — ground to a 2.5x magnification that makes the date instantly legible at a glance.

The movement deployed in the 31 mm Datejust family is Calibre 2236, a manufacture movement incorporating Rolex's proprietary Syloxi hairspring — fabricated from a silicon-based paramagnetic alloy that exhibits superior resistance to magnetic fields, temperature variations, and the effects of gravity compared to traditional Nivarox alloys. With a 55-hour power reserve and COSC-exceeding Superlative Chronometer certification, Calibre 2236 delivers the reliability that the Datejust's daily-wear proposition demands. This reference presents beautifully in its classic Rolesor form.
