The Rolex Explorer II reference 1655 holds a unique position in horological history. While the standard Explorer models focused on legibility and reliability for mountaineering, the 1655, introduced in 1971, carved its own niche as the quintessential cave explorer's watch. Its distinctive features, robust construction, and enduring appeal continue to make it a highly sought-after collector's piece, solidifying its place as a legend among Rolex enthusiasts. This article delves into the fascinating world of the Rolex Explorer II 1655, exploring its technical specifications, design variations, market value, and its enduring connection to adventure and style.
The Heart of the Beast: Caliber 1575 and Functional Design
At the heart of the Rolex Explorer II 1655 beats the robust 26-jewel Caliber 1575 movement. This automatic movement, a hallmark of Rolex engineering, provided exceptional accuracy and reliability, crucial attributes for a watch designed to withstand the rigors of extreme environments. The movement's robustness is a testament to Rolex's commitment to creating timepieces that can endure even the most demanding conditions. Beyond its accuracy and power reserve, the Caliber 1575’s reliability in challenging environments cemented the 1655's reputation as a tool watch capable of handling anything thrown its way.
The 1655's cave-exploring features are subtly integrated into its design. The most prominent is, of course, the 24-hour hand, a crucial feature for cave exploration where maintaining track of time, especially in environments devoid of natural light, is paramount. This independent hand, rotating once every 24 hours, allows the wearer to distinguish between AM and PM, even in complete darkness. This simple yet ingenious addition significantly enhanced the watch's practicality for spelunking and other activities where accurate timekeeping in low-light conditions is critical.
Further enhancing its functionality, the 1655 boasts a highly legible dial. Large, luminous hour markers and hands ensure effortless readability, even in the darkest of caves or underground environments. The robust Oyster case, water-resistant to a significant depth, protects the movement from the elements, while the screw-down crown ensures a watertight seal. These features, combined with the durable construction, made the 1655 the ideal companion for adventurers venturing into the unknown.
Rolex 1655 Dial Variations: A Collector's Delight
The Rolex Explorer II 1655 is known for its dial variations, which add to the watch's allure and collectibility. These variations, often subtle, are highly prized by collectors and can significantly impact the watch's value. Key variations include differences in the lume plots (the luminous material on the hour markers and hands), the font style used for numerals and text, and the color of the dial itself. Some dials exhibit a richer, more creamy patina over time, adding to their character and desirability.
The early 1655s often featured a matte black dial with gilt (gold-colored) hour markers and hands, while later versions might have transitioned to a slightly different shade of black or have variations in the lume. These subtle differences are meticulously documented by collectors and enthusiasts, creating a rich tapestry of variations that make each 1655 unique. Understanding these dial variations is key to appreciating the nuances and value of individual pieces. The subtle aging and patina development on the dial further adds to the appeal and historical significance of a vintage 1655.
