Rolex Datejust 31 18ct Yellow Gold & Diamonds — Red Ombré Diamond-Set Dial | Ref. 278288RBR

Reference 278288RBR represents one of the most visually dramatic executions in the current Datejust 31 catalogue: an 18ct yellow gold and diamond case paired with a red ombré dial set throughout with diamonds, and a bezel set entirely with brilliant-cut stones. This is gem-setting as artistic statement — a watch in which the horological architecture serves as a canvas for Rolex's lapidary craftspeople, who hand-select and individually set each stone to exacting standards of symmetry and brilliance.

Calibre 2236 provides the movement foundation — Rolex's dedicated small-calibre manufacture movement with a Syloxi silicon hairspring and COSC chronometer certification. The perpetual, mechanical self-winding construction offers approximately 55 hours of power reserve and meets the same precision standards applied across all Rolex production, regardless of the outer complexity of the watch's gem setting. The 31 mm yellow gold case achieves 100 metres water resistance, and the 18ct yellow gold bracelet completes a fully precious-metal ensemble of considerable material value.

The ombré red dial — graduating in intensity from centre to periphery while carrying its own diamond hour markers — places the 278288RBR in a select tier of Datejust references that transcend utilitarian purpose to become wearable art objects. This piece arrives in like-new condition with box and papers, ensuring complete provenance. It will appeal to collectors at the intersection of high jewellery and horology: those for whom the watch is as much a jewellery purchase as a timekeeping one, and who require the backing of Rolex's manufacture movement and service network to support their investment.
