Rolex Explorer II

The Rolex Explorer II Ref. 226570 carries forward the legacy of one of Rolex’s most purpose-built tool watches, engineered for explorers and adventurers who navigate extreme environments. Equipped with a fixed 24-hour bezel and a bold GMT hand, it enables clear day-night tracking even in polar or cave expeditions. Subtle refinements — including slimmer lugs, an upgraded Calibre 3285 movement, and improved Chromalight lume — give this generation a balanced mix of toughness and refinement.
