Measuring 41 mm across, the Oyster case features a monobloc middle case, solid case back, and a screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres. Scratch-resistant sapphire crystal with a Cyclops lens over the date tops the case, while the Everose Rolesor construction extends to the five-piece-link Jubilee bracelet, secured by a folding Oysterclasp with Easylink 5 mm comfort extension link.
The slate dial carries Roman numeral indices and a Chromalight display offering long-lasting blue luminescence for low-light legibility. At the heart of the watch is the Calibre 3235, a perpetual mechanical self-winding movement from Manufacture Rolex, rated to a precision of -2/+2 seconds per day after casing and COSC certified. Its paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers contribute to reliability, while bidirectional winding via the Perpetual rotor sustains an approximately 70-hour power reserve.
Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment — making reference 126301-0016 a technically complete expression of the Datejust 41 in two-tone Everose Rolesor.
