The Rolex Explorer II, a watch synonymous with adventure and exploration, boasts a rich history marked by significant design evolutions. While conceived for spelunking and other demanding activities requiring accurate timekeeping in low-light conditions, its robust build and iconic aesthetic have propelled it to become a highly sought-after collector's item. This article delves into the fascinating evolution of the Explorer II, focusing on key milestones, design changes, and market value, touching upon specific models, prices, and specifications.
Rolex Explorer II Release Date: A History in the Making
The story of the Explorer II begins not with the 16550, but earlier. The original Explorer II, reference 1655, debuted in 1971. This model, with its distinctive orange 24-hour hand, was designed to aid in distinguishing between day and night in challenging environments, a crucial feature for cave exploration. However, it was the 1985 introduction of the reference 16550 that truly marked a significant leap forward, initiating a new era in the Explorer II's evolution.
1985: The Reference 16550 – A Turning Point
The 1985 release of the reference 16550 is a pivotal moment in the Explorer II's history. This model introduced a larger 40mm case, a considerable increase from its predecessor's 39mm. This seemingly small change had a significant impact, offering improved wrist presence and better readability. The thicker case also allowed for advancements in the movement, providing enhanced durability and reliability. The 16550 also incorporated a more robust sapphire crystal, offering superior scratch resistance compared to the acrylic crystal of the 1655. This marked a clear shift towards a more modern and rugged design, reflecting the evolving needs of professional explorers.
Rolex Explorer II Models: A Diverse Lineage
The Explorer II's lineage extends beyond the 1655 and 16550. Several iterations followed, each building upon the strengths of its predecessors while incorporating subtle yet significant design refinements. Key models include:
* Reference 16570 (1989-2011): This model represented a significant upgrade, featuring the calibre 3185 movement, known for its superior accuracy and reliability. The 16570 is often considered a highly desirable model among collectors, praised for its refined design and robust performance. Variations within this reference exist, notably those with different dial variations (e.g., "Swiss" vs. "Swiss Made").
* Reference 216570 (2011-2021): This generation saw the introduction of a slightly updated case design and a significant upgrade to the movement, incorporating advancements in anti-magnetic shielding and improved shock resistance. The 216570 also benefited from a more refined bracelet.
* Reference 226570 (2021-Present): The latest iteration of the Explorer II, the 226570, features a redesigned case and bracelet, incorporating contemporary design elements while retaining the core DNA of the model. Notably, it features a more robust and refined bracelet, and subtle improvements to the dial and hands.
