The Rolex Explorer II, a robust and highly functional tool watch, has captivated watch enthusiasts for decades. Its history is rich with innovation, reflecting Rolex's commitment to pushing the boundaries of horological excellence. While pinpointing a single "release date" for the Explorer II across all its iterations is impossible, we can explore the significant milestones in its evolution, examining the key release dates of different models and delving into the features that have solidified its place as a legendary timepiece. This article will cover the history of the Explorer II, focusing on key release dates, different model variations, and its current market position. We will also address frequently asked questions concerning pricing and specifications.
Early Days and the Genesis of the Explorer II (1971):
The story of the Explorer II begins in 1971. This year saw the introduction of the reference 1655, the first-ever Explorer II. This marked a significant departure from the more understated Explorer I, designed specifically for explorers and those venturing into challenging environments. The 1655's defining feature was its 24-hour hand, a crucial addition for navigating in low-light conditions or distinguishing between AM and PM in situations where the sun's position is unreliable. This 24-hour hand, coupled with its highly legible dial and robust Oyster case, cemented the Explorer II's reputation for functionality and durability. The exact release date within 1971 is difficult to pinpoint definitively from historical records, but its introduction that year is firmly established.
This initial iteration, the Rolex Explorer II 1655, boasted a 39mm case, a significant size for the time. It was equipped with the caliber 1575 movement, a robust and reliable automatic movement known for its accuracy and longevity. The dial, typically in matte black, featured luminous hour markers and hands, ensuring optimal legibility in various lighting conditions. The bezel, a fixed 24-hour graduated bezel, further enhanced its utility for navigating by time. This original model is now highly sought after by collectors, representing a significant piece of Rolex history and a testament to the watch's enduring design.
Evolution and Refinement: The Reference 16570 (1989):
The next major evolution of the Explorer II arrived in 1989 with the reference 16570. This model saw a significant increase in case size to 40mm, a more substantial upgrade reflecting the growing trend towards larger watches. The 16570 also featured a significant improvement in the movement. It incorporated the caliber 3185, an enhanced automatic movement known for its improved accuracy, shock resistance, and overall reliability. The 16570 also marked a shift towards a more modern aesthetic, with some variations featuring a slightly updated dial design and the introduction of a sapphire crystal, a more scratch-resistant material compared to the acrylic crystals used in its predecessor. The exact release date in 1989 is again not precisely documented, but the year marks the significant shift towards the modern Explorer II.
The 16570 was available in various dial configurations, most notably the classic black dial with luminous markers and the more coveted "Polar" dial, featuring a striking white dial with black markings. This "Polar" variation quickly became a highly sought-after collector's item. Its clean, legible dial, combined with the functionality of the 24-hour hand and bezel, cemented its place as a highly desirable timepiece.
