Crafted for explorers who traverse both sunlit landscapes and subterranean depths, the 40 mm Explorer II pairs a rugged Oystersteel case with a fixed 24‑hour bezel to distinguish day from night at a glance. Its matte‑black dial features luminous hour markers and hands, plus Rolex’s signature orange 24‑hour hand—ensuring impeccable legibility in any environment. Inside beats Rolex’s Calibre 3185 self‑winding movement, delivering both GMT and date complications with Superlative Chronometer precision and a 50‑hour power reserve. Water‑resistant to 100 meters, the Explorer II rides on a robust Oyster bracelet with Oysterlock clasp and Easylink extension for secure, comfortable wear. Each piece ships in its official Rolex presentation box, complete with warranty card and full manufacturer collateral—ready for your next adventure.
