Reference 278285RBR-0023 brings together an 18 kt Everose gold round case measuring 31mm and a diamond-set bezel, framing an aubergine dial adorned with diamonds and Roman numeral hour markers — including a large VI set with 11 diamonds. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date window, while a solid case back and screw-down Twinlock crown contribute to water resistance rated to 100 metres.
The watch rides on an 18 kt Everose gold President bracelet featuring semi-circular three-piece links and a concealed folding Crownclasp. Powering the timepiece is Rolex Calibre 2236, a perpetual, mechanical, self-winding movement with a Syloxi silicon hairspring, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. Precision is rated at -2/+2 seconds per day after casing, with Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards.
This example is unworn and offered as a complete set, accompanied by the Rolex box and Rolex card. The date complication features instantaneous setting with a rapid-set function and stop-seconds for accurate time adjustment.
