The Rolex Explorer II, a robust and reliable tool watch designed for exploration and adventure, has captivated watch enthusiasts for decades. Its iconic design, coupled with its unwavering performance, has cemented its place as a legend in the horological world. However, understanding how the Rolex Explorer II *works* goes beyond simply admiring its aesthetics. It involves exploring its evolution, its internal mechanisms, and the technological advancements that have shaped its capabilities. This article will delve into the intricacies of the Explorer II, covering its history, various models, pricing, and the technical features that make it such a sought-after timepiece.
Rolex Explorer II Release Date and the Genesis of a Legend:
The original Rolex Explorer II, reference 1655, debuted in 1971. Its creation was directly linked to the growing need for a watch capable of withstanding the harsh conditions faced by explorers and mountaineers. Unlike its predecessor, the Explorer I, which focused primarily on legibility and reliability in low-light conditions, the Explorer II introduced a crucial feature: the independently adjustable 24-hour hand. This hand, often referred to as the GMT hand, allowed explorers to easily differentiate between AM and PM, particularly crucial in environments where the sun’s position might be unreliable for determining the time of day. This innovative addition significantly enhanced the watch's functionality in challenging situations. The 1655 utilized a manually-wound movement, showcasing Rolex's commitment to robust and dependable mechanics.
Rolex Explorer II Models: A Chronological Journey:
The Explorer II's journey hasn't been static. Several iterations have followed the original 1655, each building upon its predecessor's strengths and incorporating new technologies.
* Reference 1655 (1971-1984): This first-generation model, with its distinctive orange 24-hour hand, is highly sought after by collectors. Its manually wound movement, caliber 1570, was a testament to Rolex's horological expertise. The dial featured tritium lume, giving it a unique vintage aesthetic.
* Reference 16550 (1984-1989): This reference marked a significant shift, introducing the automatic caliber 3085 movement. This update offered improved accuracy and convenience compared to the manually wound predecessor. The orange hand remained, though the lume transitioned to a different material.
* Reference 16570 (1989-2011): This model saw a substantial redesign. The most notable change was the switch to a luminescent white 24-hour hand. The case size remained largely unchanged, but subtle modifications to the dial and bezel further refined the aesthetic. This generation utilized the caliber 3185 movement, a highly reliable and robust automatic movement known for its precision and power reserve.
* Reference 226570 (2011-Present): The current generation Explorer II boasts a larger 42mm case, a significant departure from its predecessors. This increase in size improved readability and overall ergonomics. The 226570 retains the white 24-hour hand and incorporates the updated caliber 3285 movement, featuring a Chronergy escapement for increased shock resistance and improved efficiency. The updated movement also offers a longer power reserve. This model represents the culmination of Rolex's continuous refinement of the Explorer II, marrying robust functionality with modern aesthetics.
