The Rolex Explorer II, a rugged and reliable tool watch designed for exploration and adventure, has captivated watch enthusiasts for decades. Its iconic design, robust construction, and high-precision movement have cemented its place as a legend within the horological world. However, the story of the Explorer II isn't a simple one; it's a rich tapestry woven from several distinct generations, each with its own unique character and appeal. While the reference to "MOP" (Mother-of-Pearl) dial in the title is unconventional for the typically utilitarian Explorer II, it invites us to consider the possibilities of customization and the evolution of the model's aesthetic, even if officially such a dial configuration doesn't exist. This article will delve into the various iterations of the Rolex Explorer II, exploring its evolution, key features, and the enduring appeal that makes it a sought-after timepiece.
Rolex Explorer II Models: A Chronological Journey
The history of the Rolex Explorer II can be divided into distinct generations, each marked by significant design and technical improvements:
* Rolex Explorer II 1655 (1971-1984): The Original Explorer
The 1655, the first-generation Explorer II, is highly coveted by collectors. Its defining characteristic is the fixed orange 24-hour hand, a crucial feature for differentiating day from night in low-light conditions, a necessity for cave explorers and those venturing into challenging environments. This model featured a distinctive, slightly larger case (39mm) than its predecessor, the Explorer I, and a matte black dial with luminous hour markers and hands. The movement, a caliber 1570, was a robust and reliable workhorse, known for its accuracy and durability. The 1655 also featured a distinctive "freccione" or arrow hand on the 24-hour hand, making it easily distinguishable from other Rolex models. Variations exist within the 1655 production run, with differences in dial and hand lume (Tritium versus later Radium) affecting their value and desirability. Finding a well-preserved 1655 today is a testament to both its quality and its enduring popularity.
* Rolex Explorer II 16570 (1984-2011): The Polished Evolution
The 16570 marked a significant shift in the Explorer II's design. While retaining the core functionality of the 24-hour hand, it introduced a polished bezel, a change that polarized opinions among collectors. The case size remained at 39mm, but the overall aesthetic was subtly refined. The movement was upgraded to the caliber 3185, a self-winding mechanical movement known for its superior accuracy and power reserve. The dial designs also saw some changes, with variations including a matte black dial, a white dial (less common), and a transition from tritium lume to luminova. The 16570 represents a more refined and polished version of the original Explorer II, attracting a broader range of wearers.
