The Rolex Explorer II, a rugged tool watch designed for exploration and adventure, has captivated collectors for decades. Its iconic design, robust build, and association with legendary expeditions have cemented its place as a highly desirable timepiece. Within the lineage of Explorer II models, the 16570, produced from 1989 to 2011, holds a special place, largely due to its incorporation of the Caliber 3186 movement. This article delves into the investment potential of Rolex Explorer II watches equipped with the 3186 movement, considering its technical advancements, historical context, and potential pitfalls. We will also explore related topics such as common Rolex Explorer II problems, a review of the predecessor 16550, and a deeper look at the 16570 itself.
The Caliber 3186: A Significant Upgrade
Before the 3186, the Explorer II 16570's predecessor, the 16550, utilized the Caliber 3085. While a reliable movement, the 3085 lacked some of the advancements present in the 3186. The 3186, introduced in 2005, marked a significant leap forward in Rolex's horological technology. This self-winding movement retained the independently adjustable hour hand, a crucial feature for navigating in low-light conditions, but incorporated several key improvements. Most notably, the 3186 featured the then-revolutionary blue Parachrom hairspring.
The Parachrom hairspring, made from a paramagnetic alloy, offered superior resistance to shocks and magnetic fields compared to traditional hairsprings. This enhanced resilience translated to improved accuracy and reliability, crucial qualities in a watch designed to withstand the rigors of extreme environments. The 3186 also boasted increased power reserve, improved lubrication, and enhanced shock absorption, contributing to its longevity and precision. This technological upgrade is a major factor contributing to the desirability and potential investment value of the Explorer II 16570.
Rolex Explorer II 16570: A Collector's Favorite
The Rolex Explorer II 16570, produced between 1989 and 2011, is highly sought after by collectors for several reasons. Beyond the technological advancements of the 3186 movement, the 16570 boasts a classic and timeless design. Its 40mm case size, suitable for a wide range of wrists, offers a balanced aesthetic. The distinct orange hand, indicating the 24-hour hand, adds a touch of boldness and functionality, while the overall design remains understated and elegant. The 16570 was available in various dial variations, including black and white, further contributing to its appeal to collectors.
The 16570's production run spanned over two decades, leading to subtle variations in dial details and case construction over the years. These variations, often referred to as "transitional" models, can command premium prices among discerning collectors who appreciate the nuances of Rolex's production history. These subtle differences, combined with the inherent scarcity of certain variations, contribute significantly to the investment potential of specific 16570 references.
