The Rolex Explorer II 16570 is a legendary timepiece, revered by watch enthusiasts for its ruggedness, functionality, and understated design. Understanding its history is crucial for appreciating its significance in the world of horology. This article dives deep into the history of the Rolex Explorer II 16570, exploring its origins, evolution, and enduring appeal. Guys, let's get started on this horological journey!

Origins of the Explorer II

Before we delve into the specifics of the 16570, it's essential to understand the context of the Explorer II's creation. The original Explorer II, reference 1655, was introduced in 1971. It was designed as a tool watch for explorers, particularly speleologists (cave explorers), who needed a reliable timepiece to track time in environments where it was impossible to distinguish between day and night. The 1655 featured a distinctive 24-hour fixed bezel and an additional 24-hour hand, allowing the wearer to easily read the time in a 24-hour format. While innovative, the 1655 wasn't an immediate commercial success, and its unique design earned it nicknames like "Steve McQueen" (though he wasn't actually known to wear one) and "Freccione" (Italian for "big arrow," referring to the large 24-hour hand).

The Explorer II was born from the necessity of providing a reliable timekeeping tool for adventurers facing extreme conditions. Rolex recognized the need for a watch that could withstand the rigors of exploration while offering essential functionality for navigating challenging environments. The initial Explorer II 1655 laid the groundwork for future models, establishing the core features that would define the Explorer II line.

The Explorer II 1655, though not a commercial hit initially, paved the way for future models by introducing the 24-hour bezel and hand, crucial for adventurers in environments lacking natural day/night cues. This pioneering spirit of Rolex in catering to specific professional needs set the stage for the evolution of the Explorer II series, emphasizing functionality and robustness.

The development of the Explorer II also reflected Rolex's commitment to innovation and its close relationship with the world of exploration. By collaborating with professionals in various fields, Rolex gained valuable insights into the needs and challenges faced by those who pushed the boundaries of human exploration. This collaborative approach ensured that the Explorer II was not just a stylish accessory but a practical tool designed to meet the demands of real-world adventures.

The Introduction of the 16570

The Rolex Explorer II 16570 was introduced in 1989, marking a significant update to the Explorer II line. It replaced the 16550, which was produced for a relatively short period and is now considered a transitional model. The 16570 brought with it several key improvements and refinements that solidified the Explorer II's place as a modern classic.

One of the most notable changes was the movement. The 16570 was initially powered by the Caliber 3185, and later by the Caliber 3186. These movements offered enhanced reliability and accuracy compared to the earlier Caliber 3085 found in the 16550. The Caliber 3185/3186 movements also featured an independent 24-hour hand, which could be set independently of the main hour hand. This allowed the wearer to easily track a second time zone, making the 16570 a true GMT watch.

The design of the 16570 was also refined. The case was slightly slimmer and more streamlined than its predecessor, and the dial was available in two options: black and white (often referred to as "Polar"). The white dial version is particularly popular among collectors due to its distinctive look and legibility. The hands and hour markers were also updated, featuring luminous material for enhanced visibility in low-light conditions.

The Explorer II 16570's introduction marked a pivotal moment, bringing significant enhancements in movement technology and design aesthetics that cemented its status as a modern classic. Rolex's meticulous attention to detail and commitment to improvement ensured that the 16570 was a worthy successor to the earlier models, offering enhanced functionality and a more refined overall appearance.

The 16570 quickly gained popularity among watch enthusiasts and professionals alike. Its robust construction, reliable movement, and versatile design made it an ideal companion for a wide range of activities, from outdoor adventures to everyday wear. The Explorer II's understated elegance and practical functionality appealed to those who appreciated a watch that was both stylish and functional.

Key Features and Variations

The Rolex Explorer II 16570 boasts several key features that contribute to its appeal and functionality. As mentioned earlier, the watch is equipped with a 24-hour fixed bezel and an independent 24-hour hand, allowing the wearer to track a second time zone. The stainless steel case is robust and water-resistant to 100 meters (330 feet), making it suitable for various activities. The sapphire crystal is scratch-resistant, ensuring excellent visibility and durability.

The dial is available in black and white (Polar) options. The white dial version is particularly sought after for its unique appearance and high legibility. The hands and hour markers are coated with luminous material, providing excellent visibility in low-light conditions. The watch is fitted with a stainless steel Oyster bracelet, known for its comfort and durability.

Throughout its production run, the 16570 underwent several minor variations. These variations can be identified by examining details such as the dial markings, the type of luminous material used, and the presence or absence of lug holes. For example, early 16570 models featured tritium luminous material, which was later replaced by Super-LumiNova. Some models also had lug holes, while later models did not.

The Rolex Explorer II 16570's enduring appeal stems from its meticulously designed features and subtle variations, each adding to its unique character and collectibility. The combination of robust construction, functional design, and attention to detail makes the 16570 a versatile and reliable timepiece that can be appreciated by watch enthusiasts of all levels.

Collectors often seek out specific variations of the 16570, such as models with specific dial markings or those with the original tritium lume. These variations can command a premium in the secondary market, reflecting the desirability and collectibility of the 16570.

The Caliber 3185 and 3186 Movements

The Rolex Explorer II 16570 is powered by two main movements: the Caliber 3185 and the Caliber 3186. The Caliber 3185 was the initial movement used in the 16570, while the Caliber 3186 was introduced later in the production run. Both movements are automatic, self-winding movements that offer excellent accuracy and reliability.

The Caliber 3185 features a free-sprung balance, a Breguet overcoil, and a hacking seconds function (meaning the seconds hand stops when the crown is pulled out for precise time setting). The independent 24-hour hand can be set independently of the main hour hand, allowing the wearer to easily track a second time zone.

The Caliber 3186 is an evolution of the Caliber 3185, with several improvements and refinements. One of the most notable changes is the improved design of the 24-hour hand mechanism, which eliminates the "wobble" that could sometimes occur in the Caliber 3185. The Caliber 3186 also features a Parachrom hairspring, which is more resistant to shocks and temperature variations.

The heart of the Rolex Explorer II 16570 lies in its Caliber 3185 and 3186 movements, each representing a pinnacle of Rolex's engineering prowess and commitment to precision. These movements are not just timekeeping devices; they are intricate works of art that showcase Rolex's dedication to innovation and quality.

The transition from the Caliber 3185 to the Caliber 3186 was a significant step in the evolution of the Explorer II. The improvements introduced in the Caliber 3186 enhanced the watch's overall performance and reliability, solidifying its reputation as a top-tier timepiece.

Production Years and Timeline

The Rolex Explorer II 16570 was in production from 1989 to 2011, making it one of the longest-running Explorer II models. Throughout its production run, the 16570 underwent several minor changes and variations. Here's a timeline of key events:

Market Value and Collectibility

The Rolex Explorer II 16570 holds a strong position in the pre-owned market, with prices varying depending on condition, age, and specific features. Models in excellent condition with original boxes and papers command a premium, as do those with rare dial variations or early production features.

The white dial (Polar) version is generally more sought after than the black dial version, and models with the Caliber 3186 movement tend to be more valuable than those with the Caliber 3185.
