The Rolex Explorer II, a robust and highly functional tool watch, holds a special place in the brand's history and the hearts of adventurous watch enthusiasts. While not as widely known as its sibling, the Explorer, the Explorer II boasts a unique complication designed specifically for exploration in challenging environments, particularly those with extended periods of darkness. This article delves into the history and evolution of the Explorer II, focusing on its key features, notable iterations, and ultimately aiding in the decision of which Rolex Explorer to buy, referencing various related topics such as the Rolex Explorer Wikipedia entry, a Rolex Explorer guide, the Rolex Explorer Everest connection, all Rolex Explorer models, the Rolex Explorer 36mm white dial option, and the overall question of which Rolex Explorer to buy.
The Genesis of the Explorer II and the Ref. 1655:
The story of the Explorer II begins not in the modern era, but much earlier. The original Explorer II, reference 1655, debuted in 1971. This watch represented a significant departure from the standard Explorer, incorporating a crucial feature for cave exploration and other activities where distinguishing day from night is critical: an independently adjustable 24-hour hand. This GMT hand, as it's commonly known, allowed explorers to track a second time zone, often used to keep track of the home time while navigating in challenging or remote locations. The 1655 featured a fixed bezel with 24-hour markings, a robust Oyster case, and the reliable Calibre 1570 movement. Its design, while less refined than later models, was undeniably purposeful and practical, reflecting its intended use. The orange 24-hour hand, a defining characteristic of the 1655, became an iconic element of the Explorer II lineage. This first generation, though now a highly sought-after collector's piece, lacked some of the refinements and robustness seen in later models. The relatively small size of the case by today's standards and the use of acrylic crystal also highlight its vintage nature.
The Long Reign of the Ref. 16570:
The modern era of the Explorer II truly begins with the introduction of the reference 16570 in 1989. This model represented a significant upgrade in both aesthetics and technology. The move to the Calibre 3185 movement marked a substantial leap forward. This robust and reliable movement, a workhorse within the Rolex family, provided increased accuracy and longevity. While still featuring the adjustable GMT hand and fixed bezel, the 16570 boasted a more refined case design, a larger 40mm case size (a significant increase from its predecessor), and the upgrade to a sapphire crystal for enhanced scratch resistance. This combination of improved functionality and enhanced durability solidified the Explorer II's position as a true professional tool watch.
The 16570 remained in production for over two decades, undergoing subtle yet significant changes throughout its lifespan. Early examples featured a slightly different dial layout and hand style compared to later productions. These subtle variations have become a focus for collectors, with variations in dial and hand configurations driving significant differences in value. The 16570's long production run allowed Rolex to refine its design and manufacturing processes, resulting in a consistently high-quality product. Its widespread appeal and enduring design have made it a perennial favorite amongst collectors and enthusiasts alike. The simple, clean dial, the unmistakable orange 24-hour hand, and the robust case all contributed to its enduring popularity.
