The Explorer II 226570 is built for adventurers who challenge the extremes. Its robust 42 mm Oystersteel case and fixed 24‑hour bezel work in tandem with a striking orange 24‑hour hand — making it easy to distinguish day from night, even underground or on polar expeditions.
The high-contrast black (or white) dial features bold Chromalight markers and hands that emit a long-lasting blue glow, ensuring clarity in low light. Inside, the dependable Calibre 3285 movement delivers around 70 hours of power reserve and offers GMT functionality for tracking a second time zone.
Finishing the design is a rugged Oyster bracelet, secured by a locking Oysterlock clasp and supported by a 5 mm Easylink extension — comfortable and secure for any journey. With water resistance up to 100 meters, the Explorer II is a resilient and capable companion for both remote terrains and urban adventures.
