At 36 mm, the Datejust 116244-0064 is built around a monobloc middle case in Oystersteel, sealed by a screw-down case back and a screw-down Twinlock winding crown for waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date window, while the bezel is set with diamonds for a striking contrast against the clean Oystersteel case.
The white dial features index hour markers and is driven by Rolex Calibre 3235 — a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 70 hours. Its paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to a precision rating of -2/+2 seconds per day after casing, and the movement carries Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards.
The watch is worn on an Oystersteel Jubilee bracelet with five-piece links, secured by a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link. Functions include centre hour, minute, and seconds hands alongside an instantaneous date display with secure rapid-setting and stop-seconds for precise time adjustment.
