The Rolex Explorer II reference 226570 is the current generation of this iconic exploration watch, introduced in 2021 to mark the model’s 50th anniversary. It features a robust 42mm Oyster case in corrosion-resistant Oystersteel, paired with a fixed 24-hour graduated bezel and a Twinlock screw-down crown. Powered by the advanced Calibre 3285 automatic movement with approximately 70 hours of power reserve, it includes an independent second time zone (distinctive orange 24-hour hand) and a date display under the Cyclops lens. Available with either a classic black dial or the highly popular white “Polar” dial, both featuring Chromalight luminous markers and hands. Fitted with a solid Oyster bracelet with Oysterlock safety clasp and Easylink 5mm comfort extension. Water-resistant to 100 metres, it remains one of the most practical and durable Rolex sports watches for everyday wear and adventures.
