Measuring 31mm across its round Oyster case, the Datejust 278384RBR-0026 is constructed in White Rolesor, combining Oystersteel with white gold. The bezel is set with diamonds, while a screw-down winding crown with Twinlock double waterproofness system and a solid screw-down case back ensure water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case.
The dark grey dial features Roman numeral hour markers and is paired with centre hour, minute, and seconds hands. An instantaneous date display with rapid setting and stop-seconds functionality round out the time-telling features. The dial sits behind a solid case back and is read through the magnifying Cyclops lens positioned directly over the date.
Power comes from the perpetual, mechanical, self-winding Calibre 2236 — a Manufacture Rolex movement with a Syloxi silicon hairspring and Paraflex shock absorbers, offering a precision of -2/+2 seconds per day and approximately 55 hours of power reserve. The Jubilee bracelet features five-piece links in Oystersteel and fastens with a concealed folding Crownclasp. The movement is COSC certified.
