Rolex Datejust 31 Yellow Gold — Champagne Diamond Bezel Dial | Ref. 278288RBR

The Datejust 31 in solid 18 ct yellow gold represents Rolex's commitment to precious metal watchmaking in a refined mid-size format. Reference 278288RBR elevates this proposition further with a diamond-set bezel surrounding a champagne-toned dial indexed with luminous markers, creating an object of jewellery-grade luminosity that never strays from horological purpose.

Powering this 31 mm Oyster case is Calibre 2236, a manufacture movement developed by Rolex specifically for mid-size and ladies' models. The 2236 incorporates a silicon Syloxi hairspring — offering exceptional resistance to magnetic fields and temperature variation — and delivers a 55-hour power reserve at 28,800 vph. A Superlative Chronometer certification confirms chronometric precision of -2/+2 seconds per day. The President bracelet, with its characteristic three-piece rounded links, is crafted entirely in yellow gold and fastens via a concealed Crown clasp.

The 278288RBR is a statement piece within the Datejust family, attracting collectors who regard the diamond bezel as the definitive finishing touch on a yellow gold dress watch. In the 31 mm format, the watch achieves a jewellery-watch balance rarely equalled — delicate enough for the most formal occasions, yet underpinned by Rolex's formidable technical standards. Champagne dials on yellow gold are historically among the most collectible Datejust variants, and this reference maintains that distinguished lineage.
