The Rolex Explorer, and its robust sibling the Explorer II, stand as testaments to Rolex's unwavering commitment to precision, durability, and adventure. Like all Oyster Perpetual timepieces within Rolex's Professional collection, they represent two monumental achievements in horological history, directly attributable to the vision of Hans Wilsdorf: the Oyster case and the perpetual rotor self-winding mechanism. These innovations, combined with decades of relentless refinement, have cemented the Explorer and Explorer II's place as iconic instruments, equally at home scaling Himalayan peaks as they are navigating the daily challenges of modern life. This article delves into the legacy of the first Rolex Explorer II, exploring its design, evolution, and enduring appeal.
The story of the Explorer II begins not with a specific date, but with a legacy. The original Rolex Explorer, introduced in 1953, was born from the brand’s involvement in the 1953 British Mount Everest expedition. This pioneering watch, designed for extreme conditions, established the fundamental principles that would underpin the development of its successor. The need for a timepiece capable of handling even more demanding environments, one offering enhanced functionality for explorers and adventurers, led to the creation of the Explorer II.
While the precise date of the first Explorer II's introduction is often debated among collectors, it generally accepted to be in 1971. This marked a significant step forward in Rolex's professional watchmaking. The Explorer II wasn't merely a larger, more rugged version of its predecessor; it incorporated a crucial new feature – the 24-hour hand. This addition proved revolutionary, allowing explorers to easily distinguish between day and night in challenging conditions, particularly in caves or environments with limited sunlight. This seemingly simple addition significantly increased the safety and practicality of the watch for professionals working in extreme environments.
The Rolex Explorer II Size Chart, Guide, and Dial Details:
Understanding the dimensions of the Explorer II is crucial for potential buyers. Over the years, Rolex has introduced various iterations, leading to subtle differences in size. While a precise Rolex Explorer II size chart encompassing every reference number would be extensive, some key parameters can be highlighted:
* Case Diameter: The early Explorer II models generally featured a 39mm case diameter. Later iterations, such as the reference 16570 and the current 226570, have seen a slight increase, although the difference might not be immediately noticeable to the untrained eye. This slight increase contributes to improved wearability and visibility.
* Lug-to-Lug: This measurement, often overlooked, is crucial for assessing comfort. The lug-to-lug distance on the Explorer II varies depending on the specific reference, but generally falls within a range comfortable for a wide variety of wrist sizes.
* Rolex Explorer II Bezel: The Explorer II's bezel is a defining feature. The fixed 24-hour bezel, made of durable materials like ceramic (in modern models) or aluminum (in vintage models), is critical for the watch's functionality. The graduated markings allow for easy reading of the 24-hour hand, ensuring clear day/night differentiation.
* Rolex Explorer II Dial Size: The dial size is intrinsically linked to the case diameter. While the overall proportions remain consistent across different references, minor variations exist due to changes in font sizes, indices, and the inclusion of date windows.
