The Rolex Explorer II is more than a tool watch. It is a bold statement of function, endurance, and technical clarity. Originally introduced in 1971, the Explorer II was designed for professional spelunkers, adventurers, and Arctic explorers who needed a reliable timepiece in low-light conditions. Over the years, Rolex has refined this model, maintaining its rugged spirit while introducing mechanical and aesthetic enhancements that cater to modern collectors.
In this article, we will take a detailed look at three key references in the Rolex Explorer II lineage: the reference 1655, the 16570, and the contemporary 226570. Each has its own unique character, innovations, and historical footprint. Whether you are a seasoned collector or a newcomer curious about Rolex Watches, this guide will help you appreciate the technical and visual evolution of the Explorer II.
3 Rolex Explorer II Models
Reference 1655: The Original Pathfinder (1971–1985)
The Rolex Explorer II ref. 1655, nicknamed “Steve McQueen” (despite no evidence that he wore one), stands as the foundation of the line. It was Rolex’s response to specific demands of professionals working in complete darkness, such as cave explorers. This reference was the first to feature a fixed 24-hour bezel and an independently operating orange 24-hour hand.
Design and Aesthetics
The 1655 featured a 40mm stainless steel case, straight hands, and a matte black dial. What truly set it apart was its oversized orange 24-hour hand and the densely packed minute markers. These features provided high visibility and clarity, essential for explorers disoriented by dark environments. The fixed bezel, engraved with a 24-hour scale, reinforced the idea of functionality over flair.
Movement and Technical Features
The watch was powered by the caliber 1575, a robust and reliable movement. It lacked an independently adjustable GMT hand, meaning the 24-hour hand was synced with the main hour hand. While this limited the watch’s flexibility, it fulfilled its purpose as a clear day-night indicator.
Today, the 1655 is a collector’s gem, admired for its distinct character and rarity. It marked Rolex’s bold step into professional tool watches designed for extreme environments.
Reference 16570: A Bridge Between Generations (1989–2011)
Fast-forward to 1989, and Rolex released the reference 16570. This model retained the Explorer II’s core identity but introduced significant improvements in terms of movement, aesthetics, and everyday versatility.
Visual Changes and Dial Options
The 16570 featured a 40mm case like its predecessor but with a more refined appearance. The hour markers were now applied with white gold surrounds, giving the dial a more luxurious feel. It was offered in both black and white (“Polar”) dials, with the white version becoming a fan favorite due to its crisp, clean look and strong legibility.
Enhanced Movement
This generation began with the caliber 3185, later upgraded to the 3186. Both offered an independently adjustable GMT hand, allowing true dual-time functionality. This brought the Explorer II closer to its GMT-Master II sibling in terms of practicality.
The movement upgrade also introduced improved shock resistance and a Parachrom hairspring, enhancing the watch’s reliability under varying conditions. These technical refinements aligned with the demands of the modern traveler and outdoor enthusiast.
The reference 16570 remained in production for over two decades, a testament to its design success and functional appeal. It became a go-to choice for those wanting an understated yet durable companion, all while enjoying a more accessible Rolex Watches Price.
Reference 226570: The Modern Evolution (2021–Present)
The current Explorer II, reference 226570, was launched in 2021 to mark the 50th anniversary of the model. This watch embodies five decades of innovation, combining vintage-inspired aesthetics with cutting-edge Rolex engineering.
Visual Heritage, Modern Feel
The 226570 is housed in a 42mm Oystersteel case, larger than its predecessors but still faithful to the Explorer II design. The watch features both black and white dial options, with the Polar dial once again proving popular among collectors. The orange 24-hour hand is back in full force, echoing the design of the original 1655.
Despite the size increase, Rolex refined the case’s proportions, making the lugs and bezel slightly slimmer. The result is a more balanced look that wears comfortably even on smaller wrists.
Rolex Caliber 3285
The real advancement lies beneath the surface. The 226570 is powered by the caliber 3285, a state-of-the-art movement that offers 70 hours of power reserve, Chronergy escapement, and excellent magnetic resistance. This engine is a pinnacle of Rolex Watches Movement, delivering accuracy and durability at the highest level.
Other updates include an upgraded bracelet with Easylink extension and improved lume visibility in low-light settings. It is a robust, luxurious, and modern tool watch that bridges the past with the present.
