Rolex Explorer II (16570) – Chrono Swiss Watch

Pre-Owned 40mm Rolex Explorer II (16570) The Rolex Explorer II was first introduced in 1971 as a tool watch designed for cave explorers and adventurers who needed a timepiece that could withstand extreme conditions. The initial model, the Ref. 1655, featured a 24-hour bezel and an orange 24-hour hand, which made it easier to distinguish between day and night in environments where sunlight is scarce. Since then, the Explorer II has undergone several updates and improvements, including the addition of a new movement, a larger case size, and a more refined design. Today, it remains one of Rolex’s most iconic and sought-after models, known for its durability, accuracy, and distinctive style. This example was recently serviced in 2025 and has service hands, offering years of worry-free wear. It comes complete with box and papers.
