The Rolex Explorer II reference 1655 occupies a unique and highly coveted position within the pantheon of Rolex sports watches. While its sibling, the Explorer I, focused on straightforward timekeeping for expeditions, the 1655 was specifically engineered with the needs of cave explorers in mind. This article delves deep into the nuances of this legendary timepiece, exploring its history, design features, variations, and value, providing a comprehensive guide for collectors and enthusiasts alike.
Rolex Explorer II 1655 Specs:
The heart of the 1655 beats with the robust Caliber 1575, a 26-jewel automatic movement renowned for its reliability and accuracy. This movement, a significant upgrade from its predecessors, boasts a power reserve of approximately 48 hours. Beyond the movement, the 1655's specifications highlight its purpose-built nature:
* Case: 40mm stainless steel Oyster case, known for its water resistance (though precise ratings vary across production years and service histories). The case is designed for durability, capable of withstanding the rigors of exploration.
* Crystal: Acrylic crystal, which while prone to scratching, offers superior shatter resistance compared to sapphire crystal, a crucial consideration for cave exploration.
* Crown: The screw-down crown ensures water resistance, a vital feature for any watch intended for use in potentially wet conditions.
* Bracelet: Typically fitted with the iconic Oyster bracelet, offering comfort and security on the wrist.
* Hands: The 1655 features distinctive hands, including an orange 24-hour hand, a key feature for orientation in caves and low-light conditions. The other hands are typically Mercedes-style hour and minute hands.
Rolex Explorer II Bezel:
One of the most defining features of the 1655 is its fixed 24-hour bezel. This bidirectional bezel allows for a second time zone reading, crucial for cave explorers who might need to track surface time while deep underground. The 24-hour graduation is crucial for differentiating between AM and PM, a vital safety feature in challenging environments. The bezel's construction is robust, built to withstand impacts and the wear and tear of exploration. The matte finish of the bezel adds to its utilitarian aesthetic.
Rolex Explorer 1655 Dial Variations:
The dial variations of the Rolex Explorer II 1655 are a significant factor influencing its collectibility and value. Several subtle differences exist across different production years:
* Mark I: Early production models often feature a matte black dial with luminous plots that have aged to a creamy patina over time. These early dials are highly sought after by collectors.
* Mark II: Later production models often exhibit a slightly glossier dial, with the luminous material sometimes exhibiting a different aging characteristic. The transition between the Mark I and II dials is not always clearly defined, leading to much discussion among enthusiasts.
* Lume: The luminous material used on the dial and hands is another area of variation. Early dials used tritium, which over time develops a unique creamy lume, while later dials used radium or luminous paint. The different lume types contribute to the unique character of each watch.
* Text: Minor variations in the font and placement of text on the dial can also be seen. These subtle differences are key features that experienced collectors can use to authenticate and date a particular example.
Understanding these dial variations is crucial for any serious collector of the 1655. The subtle differences in lume, dial finish, and text can significantly impact the value and desirability of a particular watch.
