Rolex Datejust 31 Yellow Gold — Diamond Bezel, White Roman Dial | Ref. 278288RBR

Among the most refined expressions of Rolex's celebrated Datejust lineage, the 31 mm reference 278288RBR presents the collection's signature aesthetic in an uncompromising statement of luxury. The 18-carat yellow gold Oyster case is complemented by a diamond-set bezel housing 46 brilliant-cut stones, their brilliance framing the clean white dial adorned with raised Roman numeral indices. The precision with which Rolex's gemsetters select and place each stone — calibrated for colour, clarity, and uniformity — ensures a consistency of brilliance that sets this reference apart from superficially similar jewellery watches.

At the heart of the watch beats Calibre 2236, Rolex's proprietary manufacture movement engineered specifically for the mid-size and Lady-Datejust ranges. Oscillating at 28,800 vph and delivering approximately 55 hours of power reserve, the calibre incorporates a Syloxi silicon hairspring for enhanced resistance to temperature variation and magnetic fields. The instantaneous date mechanism with rapid-setting function and stop-seconds complication ensures accuracy to the second during synchronisation — a standard of mechanical performance usually associated with Rolex's professional sport models.

The President bracelet in matching 18-carat yellow gold — distinguished by its semi-circular three-piece links, developed exclusively for the Datejust and Day-Date — fastens via Rolex's concealed folding Crownclasp, providing a seamless integration of case and bracelet that has remained the hallmark of this configuration since its introduction. Water-resistant to 100 metres, this reference stands as the quintessential choice for the discerning collector who demands both technical excellence and enduring visual authority.
