The Rolex Explorer II, with its robust Oyster case, instantly recognizable arrow hand, and unwavering reliability, has secured its place as a legend among adventure watches. A key element of its design, often overlooked amidst the broader appreciation of its functionality, is the crown. This seemingly small component plays a crucial role in the watch's operation and overall aesthetic, contributing significantly to the Explorer II's enduring appeal. This article will delve into the intricacies of the Rolex Explorer II crown, exploring its function, design, and significance within the context of the watch's history, various models, and current market value.
The Rolex Explorer II Crown: Function and Design
The crown of the Rolex Explorer II, like all Rolex crowns, is a meticulously engineered component, embodying the brand's commitment to precision and durability. Its primary function is to wind the watch's mainspring and set the time. The screw-down crown, a hallmark of Rolex's Oyster case design, ensures water resistance, protecting the delicate internal mechanism from the elements. This is particularly crucial for a watch designed for exploration and adventure, where exposure to water, dust, and impacts is a real possibility.
The crown itself is typically made of high-quality stainless steel, seamlessly integrated with the case. Its knurled surface provides excellent grip, allowing for easy winding and time setting, even with gloves. The knurling's precise execution is a testament to Rolex's attention to detail, ensuring a comfortable and secure grip without compromising its refined aesthetic. The crown's size and placement are carefully considered for optimal usability and to maintain the watch's overall balanced design.
The screw-down mechanism of the crown is a crucial element of the Explorer II's water resistance. By screwing the crown tightly against the case, a hermetic seal is created, preventing water ingress. This feature is essential for maintaining the watch's functionality and longevity in challenging environments. The triple-locking system employed by Rolex further enhances water resistance, providing exceptional protection against water pressure.
Rolex Explorer II Release Date and Model Evolution:
Understanding the crown's role requires understanding the evolution of the Explorer II itself. The first generation Rolex Explorer II, reference 1655, was released in 1971. This model featured a distinctive orange 24-hour hand, a crucial feature for navigating in low-light conditions or differentiating between AM and PM in challenging environments. This original Explorer II, while possessing a similar crown design philosophy to later models, lacked some of the refinements introduced over subsequent iterations.
The reference 1655 was followed by the reference 16570, introduced in 1989. This model featured improvements in materials and technology, including a more refined movement and a slightly updated case design. The crown remained a key component, maintaining its functionality and reliability. The reference 16570 is often considered a highly collectible and desirable model due to its blend of classic design and improved performance.
The current generation of the Explorer II, reference 226570, launched in 2011, represents a further evolution of the design. While maintaining the core elements of the original, this model showcases improved materials, a more robust movement, and enhanced water resistance. The crown, while largely unchanged in its fundamental design, benefits from the advancements in manufacturing techniques and materials, ensuring even greater reliability and durability.
