Housed in a 40mm Oystersteel case with a monobloc middle, screw-down case back, and screw-down Twinlock winding crown, the Explorer 224270-0001 is waterproof to 100 metres. A scratch-resistant sapphire crystal protects the smooth bezel and black dial, which features a Chromalight display delivering long-lasting blue luminescence for strong legibility in low light.
Power comes from the Calibre 3230, a perpetual mechanical self-winding movement manufactured by Rolex. It offers a precision rating of -2/+2 seconds per day after casing, a bidirectional Perpetual rotor, a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and an approximate 70-hour power reserve. The movement carries Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
The Oystersteel Oyster bracelet is composed of three-piece solid links and secured by a folding Oysterlock safety clasp fitted with an Easylink 5mm comfort extension link. This example is offered as a complete set with the original Rolex box and Rolex card.
