The Genesis of the Explorer II

The Explorer II story begins with the Rolex Explorer, originally designed for explorers venturing into challenging environments. Building on this legacy, Rolex introduced the Explorer II to cater to the needs of speleologists and polar explorers. These adventurers required a watch that could differentiate between day and night in environments where sunlight was scarce or non-existent. The Explorer II, with its distinctive 24-hour bezel and additional hand, was the perfect solution. The first model, the reference 1655, was introduced in 1971. Known affectionately as the "Steve McQueen" (though he never actually wore one), it set the stage for future iterations. However, it was the 16570 that truly refined the Explorer II concept, offering enhanced functionality and a more contemporary design that resonated with a broader audience. This model marked a significant step forward, bridging the gap between tool watch practicality and everyday wearability. Its evolution reflects Rolex's commitment to continuous improvement and meeting the evolving needs of its clientele. The Explorer II 16570 isn't just a watch; it's a piece of horological history, embodying the spirit of adventure and precision that defines the Rolex brand. Understanding its origins helps us appreciate the thought and engineering that went into creating this timeless classic.

The Birth of the 16570 (1989-2011)

The Rolex Explorer II 16570 made its debut in 1989, replacing the reference 16550. This new model brought several notable upgrades. First and foremost, it featured the Caliber 3185 movement, a significant improvement in terms of reliability and precision. The 3185 movement provided enhanced timekeeping and a more robust construction, ensuring the watch could withstand the rigors of daily wear and adventurous pursuits. Another key change was the introduction of a sapphire crystal, replacing the previous acrylic crystal. Sapphire is far more scratch-resistant, adding to the watch's durability and longevity. The dial also saw some subtle but important tweaks. The hour markers were improved for better legibility, and the overall design was refined to offer a cleaner, more modern aesthetic. The 16570 was available in two dial colors: white (nicknamed "Polar") and black. Both versions were incredibly popular, each offering a distinct look that appealed to different tastes. The white dial, in particular, stood out for its high visibility and unique appearance. Over its production run, the 16570 saw a few minor updates. In the late 1990s, Rolex switched to using SuperLuminova for the luminous material on the dial and hands, improving nighttime visibility. The movement was also updated to the Caliber 3186 in the very last production years, though this change is relatively rare. The 16570 remained in production until 2011, making it one of the longest-running Explorer II models. Its enduring popularity is a testament to its timeless design and robust construction. For collectors and enthusiasts, the 16570 represents a sweet spot in the Explorer II lineage, blending vintage charm with modern reliability.

Key Features and Specifications

Let's break down the key features that make the Rolex Explorer II 16570 so special. This watch is packed with details that contribute to its functionality and aesthetic appeal. Firstly, the 40mm stainless steel case strikes a perfect balance between wrist presence and wearability. It’s robust enough to handle daily wear yet comfortable enough for all-day use. The fixed 24-hour bezel is a defining characteristic of the Explorer II. This feature, combined with the independent 24-hour hand, allows the wearer to track a second time zone or simply differentiate between AM and PM in environments where natural light is absent. The dial is available in two colors: black and white (Polar). Both versions feature luminous hour markers and hands, providing excellent visibility in low-light conditions. The sapphire crystal offers superior scratch resistance compared to the acrylic crystals found on earlier models. Inside, the 16570 is powered by the Caliber 3185 (and later, the 3186) movement. This automatic movement is known for its reliability and accuracy. It features a quickset date function and a hacking seconds feature, allowing for precise time setting. The watch is water-resistant to 100 meters (330 feet), making it suitable for swimming and snorkeling. The Oyster bracelet, made from stainless steel, is both comfortable and durable. It features a folding clasp that provides a secure fit on the wrist. The 16570 also includes a date function at the 3 o'clock position, adding to its practicality. Overall, the Rolex Explorer II 16570 is a well-rounded timepiece that combines functionality, durability, and timeless design. Its specifications reflect Rolex's commitment to quality and precision, making it a favorite among collectors and enthusiasts.

Variations and Serial Numbers

Understanding the variations and serial numbers of the Rolex Explorer II 16570 can help you identify and appreciate the nuances of different production years. The 16570 was produced from 1989 to 2011, and during this time, there were several subtle changes and updates. The earliest models, produced from 1989 to the late 1990s, featured tritium luminous material on the dial and hands. Tritium glows when new but fades over time, giving these early models a unique vintage look. Around 1998, Rolex switched to SuperLuminova, which maintains its luminosity for a longer period. The easiest way to identify a SuperLuminova dial is by looking for the "SWISS MADE" marking at the bottom of the dial. Serial numbers can also help you determine the production year of your 16570. Rolex serial numbers are unique and can be used to trace the watch back to its original production date. The serial number is typically located between the lugs at the 6 o'clock position. You'll need to remove the bracelet to see it. Online resources and databases can help you decode the serial number and determine the year of production. Another variation to note is the movement. The vast majority of 16570s are equipped with the Caliber 3185 movement. However, the very last production models (around 2010-2011) were fitted with the Caliber 3186. This movement is functionally similar but includes some minor improvements. Identifying a 3186 movement requires opening the watch, which is best left to a professional. The dial color (black or white) is another obvious variation. Both versions were produced throughout the 16570's run, and personal preference is usually the deciding factor. By paying attention to these details, you can gain a deeper understanding of the Rolex Explorer II 16570 and its evolution over time.

Why the 16570 Remains Popular

Another factor is its relative affordability compared to other Rolex models.

Finally, the 16570 has a strong connection to the history of exploration and adventure, which resonates with many watch enthusiasts. Owning a 16570 is like owning a piece of that history, a reminder of the spirit of exploration and the pursuit of knowledge. For all these reasons, the Rolex Explorer II 16570 remains a beloved and highly desirable timepiece.

Buying a Rolex Explorer II 16570: What to Look For

If you're in the market for a Rolex Explorer II 16570, here are some key things to keep in mind to ensure you're making a smart purchase. Firstly, authenticity is paramount. With the proliferation of counterfeit watches, it's essential to buy from a reputable source. Look for established dealers with a proven track record and positive reviews. Before you buy, thoroughly inspect the watch. Check the serial number and compare it to online databases to verify the production year. Examine the dial for any signs of tampering or redialing. The hour markers and hands should be original and in good condition. Pay close attention to the bezel. The numbers and graduations should be crisp and clear, and the bezel should rotate smoothly. The case should be free of any major dents or scratches. A few minor signs of wear are acceptable, but excessive damage can indicate a history of abuse. Ask about the service history of the watch. A well-maintained 16570 should have been serviced every 5-7 years. If possible, obtain documentation of any previous services. Check the bracelet for stretch and wear. The links should be tight and the clasp should function properly. If the bracelet is too loose, it may need to be repaired or replaced. Consider the dial color. Both black and white dials are desirable, but the white dial (Polar) tends to command a slight premium. Choose the dial color that appeals to you most. Be aware of the different luminous materials used over the 16570's production run (tritium vs. SuperLuminova). This can affect the watch's appearance and value. Finally, compare prices from different sources before making a purchase. Prices can vary depending on condition, provenance, and dealer reputation. By doing your homework and being diligent, you can find a great Rolex Explorer II 16570 that you'll enjoy for years to come.

Taking Care of Your 16570

Once you've acquired your Rolex Explorer II 16570, proper care and maintenance are essential to keep it running smoothly and looking its best. Here are some tips to help you take care of your prized timepiece. Regular cleaning is crucial. Use a soft cloth to wipe down the case and bracelet regularly. For more thorough cleaning, you can use a mild soap and water solution. Be sure to dry the watch completely after cleaning. Avoid exposing your 16570 to extreme temperatures, strong chemicals, and magnetic fields. These can damage the movement and other components. If you plan to swim or engage in water sports, make sure the crown is screwed down tightly to maintain water resistance. While the 16570 is water-resistant to 100 meters, it's always best to err on the side of caution. Schedule regular servicing with a qualified Rolex watchmaker. A complete service should be performed every 5-7 years. During a service, the movement will be disassembled, cleaned, lubricated, and reassembled. Worn parts will be replaced as needed. Store your 16570 in a safe place when you're not wearing it. A watch box or pouch can protect it from dust and scratches. If you're not planning to wear the watch for an extended period, consider winding it occasionally to keep the movement lubricated. Be mindful of the bracelet. Avoid banging it against hard surfaces, as this can cause scratches and damage. If the bracelet becomes loose or stretched, have it repaired by a professional. If you notice any issues with your 16570, such as erratic timekeeping or a stiff crown, don't delay in seeking professional help. Ignoring these problems can lead to more serious damage. By following these simple tips, you can ensure that your Rolex Explorer II 16570 remains a reliable and cherished companion for many years to come.
