In 2011, Rolex celebrated four decades of its iconic Explorer II, a watch intrinsically linked with exploration, adventure, and unwavering reliability. To mark this significant milestone, the brand unveiled the reference 216570, a watch that not only paid homage to its predecessor but also significantly advanced the tool watch archetype, solidifying its place as a legend in horological history. This article delves into the details of the 40th-anniversary model, exploring its design innovations, the legacy of the Explorer II line, and its enduring appeal in the context of other models like the Rolex Explorer II Polar 40mm, the Oyster Perpetual Explorer 40, and the broader market of Rolex Explorer 40 for sale, Rolex Explorer II polar price, and Rolex Explorer II price new.
The original Rolex Explorer II, introduced in 1971 as reference 1655, was designed specifically for explorers and cave divers. Its distinguishing feature, the independent 24-hour hand, allowed for easy differentiation between day and night, crucial in challenging environments where sunlight might be limited or unreliable. This groundbreaking feature, combined with its robust construction and exceptional accuracy, quickly established the Explorer II as a benchmark for professional timekeeping. However, the 1971 model, with its 39mm case, represented a certain aesthetic and functional approach that would evolve over time.
The 2011 reference 216570, celebrating the 40th anniversary, marked a significant shift. The most immediate change was the increase in case size from 39mm to 42mm. This enlargement wasn't merely an aesthetic choice; it improved the watch's overall ergonomics and enhanced readability, particularly for those with larger wrists. The larger dial provided more space for the hour markers and hands, further contributing to improved legibility, a critical factor in any tool watch.
Beyond the larger case, the 216570 boasted significant advancements in lume technology. Rolex's patented Chromalight display, featuring long-lasting luminescence, was incorporated. This upgrade ensured exceptional visibility in low-light conditions, a vital characteristic for the watch’s intended users. The intense blue glow of the Chromalight hands and markers extended the watch's functionality in dark caves, nighttime expeditions, or any situation where clear timekeeping is paramount.
Perhaps the most visually striking element of the 216570 was the return of the iconic orange 24-hour hand. After a period where the hand was presented in other colors, the vibrant orange hand reappeared, immediately recalling the original spirit and design language of the Explorer II. This bold color choice, in conjunction with the black dial, offered a stunning contrast and served as a powerful visual reminder of the watch's heritage and purpose. This vibrant orange hand is a key feature often sought after by collectors and enthusiasts, differentiating the 216570 from other Explorer II iterations.
