Explorer II Price Guide 2026

The Rolex Explorer II, introduced in 1971, was designed as a professional tool watch for speleologists and cave explorers, though it has since become a versatile timepiece appreciated by collectors worldwide. The model's most distinctive feature is its 24-hour hand and dial, which allows wearers to distinguish between day and night at a glance—a critical function for those working in environments without natural light. This innovative complication, combined with Rolex's legendary reliability and build quality, established the Explorer II as a serious instrument watch rather than a luxury accessory.

The watch has maintained a consistent design philosophy throughout its production history, with the 40mm Oyster case remaining largely unchanged since its inception. Early models featured an orange 24-hour hand, which was later changed to white on newer references. The dial typically displays a simple, legible design with applied indices and Mercedes-style hands. The Explorer II is powered by Rolex's in-house automatic movement, currently the caliber 3187 in modern versions, known for its robustness and accuracy. The watch is available in stainless steel, and Rolex has occasionally produced limited editions in precious metals.

When collecting an Explorer II, potential buyers should note that vintage references from the 1970s and 1980s command particular interest among enthusiasts. Key variants include the "Steve Fossett" reference 16570, named after the famous adventurer who wore one, and the modern 216570 introduced in 2011 with an updated movement and improved dial. The Explorer II's practical design, historical significance, and strong performance in the secondary market make it a compelling choice for both professional users and collectors seeking a versatile sports watch with genuine heritage.
