The Rolex Explorer II, a watch synonymous with adventure and exploration, stands as a testament to the brand's commitment to robust functionality and timeless design. This article delves into the specifications of this iconic timepiece, exploring its various iterations, key features, and the nuances that distinguish one model from another. We’ll cover everything from the 42mm and 36mm case sizes, the differences between the 216570 and 226570 models, pricing considerations, the coveted Polar Explorer II, lug width dimensions, and a detailed look at the reference 226570.
Rolex Explorer II 42mm: The Modern Standard
The current generation of the Explorer II, predominantly represented by the reference 226570, boasts a 42mm Oyster case. This size strikes a balance between legibility and wearability, making it suitable for a wide range of wrist sizes. The substantial case diameter contributes to the watch's robust build and inherent durability, features crucial for the demanding environments it's designed to withstand. The case itself is crafted from 904L stainless steel, renowned for its exceptional resistance to corrosion and scratching. This material choice reflects Rolex's unwavering commitment to producing watches that can endure the rigors of exploration and everyday wear.
The 42mm Explorer II is characterized by its distinctive fixed bezel with 24-hour graduations. This feature, arguably the most defining characteristic of the Explorer II, allows for easy differentiation between day and night, a critical function for adventurers navigating challenging conditions where visibility is compromised. The highly legible numerals and markers on the bezel, combined with the luminous hands and indices, ensure optimal timekeeping even in low-light situations. The luminous material, Chromalight, is a Rolex proprietary compound that offers superior luminance and prolonged visibility compared to standard luminescent materials.
The movement powering the 42mm Explorer II, caliber 3285, is a testament to Rolex's horological expertise. This self-winding mechanical movement boasts a power reserve of approximately 70 hours, ensuring reliable timekeeping even if the watch is not worn for an extended period. It incorporates several key advancements, including the Chronergy escapement, a highly efficient and reliable system that improves the watch's shock resistance and overall performance. The movement is also equipped with a Paramagnetic blue Parachrom hairspring, resistant to magnetic fields, a significant advantage in today's world filled with electronic devices.
Rolex Explorer II 36mm: A More Refined Approach
While the 42mm Explorer II dominates the market, the 36mm version offers a more refined alternative. While no longer in current production, pre-owned models remain popular among those seeking a more compact and understated Explorer II. The smaller case size makes it a more comfortable option for individuals with smaller wrists, without sacrificing the watch's essential functionality. Despite the reduced size, the 36mm Explorer II retains the signature 24-hour hand and highly legible dial, ensuring readability remains a priority.
The movement within the 36mm Explorer II differs from its larger counterpart, showcasing the evolution of Rolex's technology over time. While specific movements varied across different production runs, they are generally known for their robustness and accuracy. The smaller size, however, may impact the power reserve compared to the modern 42mm models.
