The Rolex Explorer II (Ref. 226570) is a rugged, professional-grade timepiece built for explorers, adventurers, and those who thrive in extreme environments—especially where distinguishing day from night isn’t always possible, such as in polar regions or deep caves. The model stays true to its heritage while introducing subtle refinements and modern movement technology.
Housed in a 42 mm Oystersteel case, the Explorer II is both robust and corrosion-resistant, with a satin-brushed finish that enhances its tool-watch identity. It features a fixed 24-hour bezel with engraved numerals that work in tandem with the bright orange GMT hand, allowing the wearer to track a second time zone or distinguish AM from PM.
The dial comes in two options:
- Black – With Chromalight markers and white text
- White (“Polar”) – With black-outlined hands and markers for bold contrast
Both dials include highly legible Chromalight-filled hands and indices, emitting a long-lasting blue glow in the dark.
Powering the Explorer II is Rolex’s Calibre 3285, a next-generation automatic movement offering:
- 70-hour power reserve
- Chronergy escapement
- Parachrom hairspring
- Superlative Chronometer rating (–2/+2 sec/day)
The Oyster bracelet is fitted with the Oysterlock folding safety clasp and the Easylink 5 mm comfort extension, allowing easy fit adjustments during long expeditions or everyday wear.
Water-resistant to 100 meters (330 feet) and known for its shock-resistance, GMT functionality, and legibility, the Explorer II is Rolex’s ultimate dual-time companion—perfect for travelers, mountaineers, spelunkers, and explorers alike.
