The Oyster Perpetual Yacht-Master 40 features a robust 40 mm case made from a combination of Oystersteel and Rose gold. Its design includes a monobloc middle case, a screw-down case back, and a winding crown, ensuring durability and a secure fit. The Rose gold bezel is bidirectional and rotatable with a 60-minute graduated scale and raised numerals, adding both functionality and elegance. The screw-down Triplock crown system enhances the watch's waterproof capability to 100 meters (330 feet). The crystal is scratch-resistant sapphire, with a Cyclops lens over the date for easy readability.
Inside, the Yacht-Master 40 is powered by the self-winding Perpetual mechanical movement, Calibre 3235, developed by Rolex. This movement ensures exceptional precision, rated at -2/+2 seconds per day after casing. It offers functions including central hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time adjustment. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. The bidirectional self-winding mechanism, via the Perpetual rotor, provides a power reserve of approximately 70 hours.
The watch is paired with a classic Oyster bracelet, composed of three-piece solid links, and crafted from Everose Rolesor, blending Oystersteel and Everose gold. The bracelet is equipped with a folding Oysterlock safety clasp and an Easylink 5 mm comfort extension link, offering both security and adjustability.
The chocolate dial is designed for clarity and legibility, featuring a Chromalight display with long-lasting blue luminescence, ensuring readability in all lighting conditions.
