At 31 mm, this Datejust 31 carries a round case crafted in White Rolesor, Rolex's combination of Oystersteel and white gold. The bezel is set with diamonds, while the solid case back and screw-down winding crown with Twinlock double waterproofness system keep the watch waterproof to 100 metres. A scratch-resistant sapphire crystal protects the pink dial, with a Cyclops lens positioned over the date window for easy reading.
The pink dial features a Chromalight display with long-lasting blue luminescence for legibility in low light. Powering the watch is the Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. It offers a precision of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, and a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers. The movement is COSC certified and delivers an instantaneous date with rapid setting and stop-seconds functionality.
The Oystersteel Oyster bracelet is composed of three-piece solid links and fastens with a folding Oysterclasp featuring an Easylink 5 mm comfort extension link. Reference 278384RBR-0017 is categorized with date complication and is designed for the wrist seeking a refined, diamond-accented timepiece in the enduring Datejust lineage.
