Rolex is a name synonymous with luxury and precision in the world of watches. Among their iconic models, the Rolex Explorer II stands out for its robust design, functionality, and historical significance. The Explorer II was initially launched in 1971 and has since become a favorite among adventurers, professionals, and watch enthusiasts alike. With its distinct features, including a bold design, dual time zone function, and durable construction, the Rolex Explorer II has earned its place as a top-tier watch for explorers and collectors.
The Origins of the Rolex Explorer II
The Birth of the Explorer II
The Rolex Explorer II was designed with adventurers in mind. It was introduced in 1971 as a more rugged and versatile companion to the original Explorer model. The Explorer II was meant to cater specifically to those who ventured into the extremes of the Earth’s environments—mountain climbers, spelunkers, and polar explorers. It featured a unique 24-hour display that allowed users to distinguish between day and night in environments where traditional timekeeping would be unreliable, such as in polar regions where the sun may not set for days or weeks.
Inspiration Behind the Design
The Explorer II was developed to meet the needs of polar explorers who would often face constant daylight or darkness for extended periods. The 24-hour dial served as a critical tool for these explorers, making it easier to differentiate between day and night. The watch’s design also took into consideration the need for high visibility, durability, and resistance to extreme temperatures and environments.
Key Features of the Rolex Explorer II
The 24-Hour Display
One of the standout features of the Rolex Explorer II is its 24-hour display, a key feature that separates it from many other timepieces. The dial has a fixed 24-hour scale, paired with a 24-hour hand. This feature is particularly useful in conditions where distinguishing between day and night becomes a challenge, such as in polar regions or during extended periods of travel.
The 24-hour scale is often associated with military-style watches and is favored by professionals in fields such as aviation and exploration. It ensures that the wearer can keep track of time without confusing AM and PM, a crucial aspect when navigating unfamiliar terrain.
Dual Time Zone Function
Another important feature of the Rolex Explorer II is its ability to display a second time zone. The watch is equipped with an additional hand that rotates every 24 hours. This is particularly helpful for explorers or travelers who need to keep track of the time in two different locations simultaneously. The rotating bezel, which is an essential part of the Explorer II’s design, helps in adjusting the second time zone with ease.
Robust Construction
Rolex is known for its high standards of durability, and the Explorer II is no exception. The case is crafted from 904L stainless steel, a material prized for its corrosion resistance and strength. This makes the Explorer II highly resistant to scratches and wear, ensuring that it can withstand the harsh conditions that explorers face.
The watch also features Rolex’s signature Oyster case, which is known for its water resistance. The Explorer II is water-resistant up to 100 meters, making it suitable for diving, swimming, and other water activities. Its durability ensures that it remains in top condition even after years of use.
The Movements and Caliber
The Rolex Explorer II is powered by Rolex’s in-house automatic movement, the Caliber 3187. This movement is designed for accuracy, reliability, and long-lasting performance. It boasts a power reserve of 48 hours, which is ideal for those who may not wear the watch every day. The movement also features a Parachrom hairspring, a feature that makes the watch more resistant to shocks and magnetic fields.
The movement inside the Rolex Explorer II is also COSC-certified, meaning it has passed stringent tests for accuracy. This certification ensures that the watch will perform at a high level of precision, even in the most demanding conditions.
The Design and Dial
The design of the Rolex Explorer II is both functional and stylish. The dial is characterized by its clean and clear layout, with large hour markers that are easily visible in low light. The hands are coated with luminescent material, allowing them to glow in the dark, further improving visibility in challenging environments.
The Explorer II’s case measures 42mm in diameter, offering a slightly larger size compared to other Rolex models, making it a great fit for those who prefer a more substantial presence on the wrist. The case is polished to perfection, giving the watch a luxurious yet rugged look.
The Bezel and Crystal
The bezel of the Rolex Explorer II is bidirectional and has a 24-hour scale engraved into it. This is an important feature for adventurers and travelers who need to adjust their second time zone easily. The bezel is made from durable materials, ensuring that it remains in good condition even after years of use.
The crystal is made of scratch-resistant sapphire, ensuring that the face of the watch remains clear and readable under all conditions. The sapphire crystal is one of the most durable materials used in watchmaking, offering excellent protection against scratches and impacts.
Rolex Explorer II and Its Evolution Over Time
The First Generation: 1655 (1971-1984)
The first iteration of the Rolex Explorer II, the reference 1655, was launched in 1971. It was equipped with a 24-hour fixed bezel and featured the Caliber 1570 movement. This model featured a relatively modest design, with a simple black dial, white markers, and a distinctive orange 24-hour hand that became a hallmark of the Explorer II series. The watch was designed with functionality in mind rather than aesthetics, making it a utilitarian yet reliable tool for explorers.
The 1655 had a relatively short production run, lasting until 1984. It was not initially as popular as some of Rolex’s other models, but over time, it gained recognition among watch collectors due to its unique design and purpose-driven features.
The Second Generation: 16570 (1984-2011)
In 1984, Rolex released the second generation of the Explorer II, the reference 16570. This model introduced several updates, including a new movement, the Caliber 3085, which offered improved precision and power reserve. The 16570 also featured a more refined design with better integration of the 24-hour hand and a more modern-looking dial.
The second-generation Explorer II was produced until 2011 and saw a number of incremental changes throughout its production run. The most significant change occurred in 2001, when Rolex updated the movement to the Caliber 3186, which provided even greater reliability and accuracy.
The Third Generation: 216570 (2011-Present)
In 2011, Rolex launched the third generation of the Explorer II, the reference 216570. This model introduced a number of notable changes, including a larger 42mm case size, making it more suited for modern tastes. The design was also slightly updated, with the hands and markers becoming larger and more prominent for improved legibility.
The 216570 also marked the introduction of the new Caliber 3187 movement, which provided greater shock resistance and a longer power reserve. The watch also received an updated orange 24-hour hand, which was a throwback to the original model’s distinctive design.
