The Rolex Explorer II 16570, launched in 1989, represents a pivotal moment in the history of this iconic tool watch. It stands as the third generation of the Explorer II line, succeeding the highly regarded 16550, and building upon its predecessor's robust design and functionality while introducing significant improvements. This article will delve deep into the intricacies of the 16570, exploring its design, features, variations, and enduring appeal, comparing it to its ancestor, the 16550, and ultimately establishing its place as a highly sought-after collector's piece and a testament to Rolex's unwavering commitment to horological excellence.
From 16550 to 16570: A Legacy of Exploration
Before examining the 16570 in detail, it's crucial to understand its lineage. The Rolex Explorer II 16550, introduced in 1984, was a significant departure from its predecessor, the reference 1655. The 16550 featured a larger 40mm case, a more robust construction, and the introduction of the highly reliable Calibre 3085 movement. This movement, boasting a quick-set date function and a hacking seconds mechanism, represented a significant technological advancement for the Explorer II line. The 16550 also maintained the characteristic orange hand, a crucial feature for navigating in low-light conditions, and offered the choice between a black and a white ("Polar") dial. However, the 16550, while a significant step forward, still retained some design elements that would be refined in its successor.
The Rolex Explorer II 16570: Refinements and Enhancements
The 16570, launched five years later, built upon the foundation laid by the 16550, introducing subtle yet impactful changes that enhanced both its functionality and aesthetics. The most significant upgrade was the movement. The 16570 incorporated the Calibre 3185, a further evolution of the 3085. This new movement offered improved accuracy, reliability, and a longer power reserve, solidifying the 16570's position as a robust and dependable timekeeping instrument. The Calibre 3185, a workhorse movement used in several other Rolex models, demonstrated the brand's commitment to consistent quality and performance.
Beyond the movement, the 16570 also featured refinements in its case design. While retaining the 40mm case size, Rolex subtly adjusted the case proportions, resulting in a more refined and comfortable fit on the wrist. The lugs were subtly reshaped, offering a slightly more integrated look, and the crown guards were subtly redesigned for improved protection. These seemingly minor alterations contributed to a more polished and sophisticated overall aesthetic.
