The Rolex Explorer II, a watch synonymous with exploration and rugged durability, boasts a rich history marked by significant design and technological advancements. This article delves into the "Modellpflege," or model maintenance and evolution, of the Explorer II, examining its various generations and focusing on key features like the bezel, dial, movement, case, and specific reference numbers. We’ll trace its journey from its inception to the latest iterations, highlighting the subtle yet impactful changes that have defined this iconic timepiece.
Rolex Explorer II Models: A Chronological Overview
The story of the Explorer II begins in 1971 with the introduction of reference 1655. This groundbreaking watch was designed specifically for spelunkers and explorers who needed a readily identifiable second time zone. This marked a significant departure from the more understated Explorer, positioning the Explorer II as a tool watch with enhanced functionality for demanding environments. Subsequent iterations have built upon this foundation, refining the design and incorporating cutting-edge technology.
Rolex Explorer II 1655: The Pioneer
The 1655, often referred to as the "Steve McQueen" Explorer II due to its association with the legendary actor, is highly sought after by collectors. Its defining characteristic is the orange 24-hour hand, a crucial feature for navigating in low-light conditions or distinguishing between AM and PM in different time zones. The 1655 utilized the Caliber 1570, a robust movement known for its reliability. The bezel, a fixed 24-hour bezel, was made of acrylic, which while susceptible to scratching, gave the watch a distinct vintage aesthetic. The dial, often featuring a matte finish, showcased applied indices and hands that were filled with tritium, giving off a characteristic creamy lume over time. The case, a classic Oyster case, offered excellent water resistance, a crucial element for a watch intended for adventurous use.
Rolex Explorer II 16570: The Transition
The 16570, introduced in 1989, marked a significant transition in the Explorer II’s design language. This generation saw the introduction of the Caliber 3185, a significantly improved movement offering enhanced precision and reliability. The acrylic bezel of the 1655 was replaced with a more durable, scratch-resistant sapphire crystal bezel insert. This change enhanced the watch's longevity and resistance to the wear and tear associated with outdoor activities. The dial design also underwent a subtle evolution, with slight variations in the font and lume material used. While still retaining the signature orange 24-hour hand, the overall aesthetic leaned towards a more modern interpretation. The 16570 was produced in several variations, including those with different dial colors and hand configurations. Collectors often distinguish between early and late production 16570s based on subtle details.
