At 36 mm, this Datejust 36 is built around a round Yellow Rolesor case featuring a monobloc middle case, solid case back, screw-down winding crown with Twinlock double waterproofness, and waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. The white dial features a Chromalight display with long-lasting blue luminescence for reliable legibility.
Power comes from the Calibre 3235, a perpetual mechanical self-winding movement by Rolex rated to a precision of -2/+2 seconds per day after casing and COSC certified. It offers a power reserve of approximately 70 hours, bidirectional winding via a Perpetual rotor, an instantaneous date with rapid setting, and stop-seconds for precise time setting. The oscillator uses a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers.
The watch is presented on an Oyster bracelet in Yellow Rolesor — three-piece solid links secured by a folding Oysterclasp with an Easylink 5 mm comfort extension link. The bracelet material mirrors the case, tying the overall design together in a consistent two-tone finish.
