A Lineage of Exploration: Understanding the Explorer II Heritage

To truly appreciate the Rolex 216570, it's crucial to understand its historical context within the Explorer family. The Rolex Explorer line was born from the brand's close ties to exploration and adventure, particularly mountaineering. The original Explorer, launched in 1953, was designed as a robust and legible tool watch for extreme conditions.

The Genesis of the Explorer Line

The spirit of exploration is embedded in Rolex's DNA. The brand equipped numerous expeditions to the Himalayas, including the successful ascent of Mount Everest in 1953. These real-world tests provided invaluable feedback, leading to the development of watches built to withstand the harshest environments. The Explorer was a direct result of this rigorous testing, embodying simplicity, durability, and legibility.

The Explorer II Evolution: From 1655 to 216570

The Explorer II debuted in 1971 with the reference 1655, marking a departure from the original Explorer's simplicity. The 1655 introduced a fixed 24-hour bezel and an additional 24-hour hand, primarily intended for speleologists and polar explorers who operate in environments with no day-night cycle. Subsequent iterations, including the 16550 and 16570, refined the design and movement, each building upon the Explorer II's core functionality.

The Rolex 216570 was introduced as a modern interpretation of the Explorer II, coinciding with the 40th anniversary of the original model. It represented a significant step forward in terms of size, movement, and overall presence, while staying true to the core spirit of the Explorer II. It bridged the gap between vintage charm and contemporary watchmaking expectations.

The Rolex Explorer II 216570: A Detailed Examination

The Rolex 216570 is more than just a larger Explorer II; it's a meticulously crafted timepiece with distinct features that contribute to its desirability and functionality.

Design and Aesthetics: Bold and Functional

The most immediately noticeable change with the 216570 is its increased size. It boasts a 42mm stainless steel case, a significant jump from the 40mm of its predecessor, the 16570. This larger case size provides a more contemporary wrist presence and enhances legibility, crucial for a tool watch.

• Case: The 42mm Oyster case is crafted from Rolex's 904L stainless steel (referred to as Oystersteel since 2018), known for its exceptional corrosion resistance and durability. The case features a brushed finish on the top and polished sides, striking a balance between ruggedness and refinement.
• Bezel: The fixed 24-hour bezel is a signature element of the Explorer II. On the 216570, it is made of stainless steel with engraved numerals filled with black lacquer. This bezel, in conjunction with the 24-hour hand, allows the wearer to track a second time zone or to differentiate between AM and PM in environments lacking natural light.
• Dial Options: The Rolex 216570 is available in two dial variations: black and white ("Polar"). The "Polar" white dial is particularly iconic and highly sought after. Both dials feature applied luminous hour markers and hands, providing excellent legibility in low-light conditions.
• Hands: The 216570 features larger "Maxi" hands compared to previous Explorer II models, further enhancing legibility. The iconic orange 24-hour hand is a standout design element, paying homage to the original Explorer II 1655 and adding a vibrant pop of color.
• Chromalight Display: Rolex's proprietary Chromalight luminous material is used on the hour markers and hands. This blue luminescence offers exceptional and long-lasting visibility in darkness, a crucial feature for explorers and anyone needing reliable timekeeping in all conditions.

The Heart of the Matter: Caliber 3187 Movement

Powering the Rolex 216570 is the Rolex caliber 3187 movement. This automatic, self-winding mechanical movement is a workhorse, known for its robustness, reliability, and precision. It's a significant upgrade from the caliber 3185/3186 found in the previous 16570.

• Chronometer Certification: Like all Rolex movements, the caliber 3187 is a certified Swiss chronometer, meaning it has passed rigorous testing by the COSC (Contrôle Officiel Suisse des Chronomètres) for accuracy and precision.
• Parachrom Hairspring: The movement incorporates Rolex's patented Parachrom hairspring, made from a paramagnetic alloy. This hairspring is highly resistant to magnetic fields and temperature variations, enhancing the watch's accuracy and stability.
• Paraflex Shock Absorbers: To further enhance durability, the caliber 3187 features Rolex's high-performance Paraflex shock absorbers. These provide superior protection against shocks and impacts, essential for a watch designed for adventurous pursuits.
• GMT Functionality: The caliber 3187 provides GMT functionality, allowing the wearer to track two time zones simultaneously. The independent 24-hour hand, coupled with the fixed 24-hour bezel, makes reading the second time zone intuitive and easy.
• Power Reserve: The movement offers a power reserve of approximately 48 hours, meaning the watch will continue to run for about two days when fully wound, even if not worn.

The Oyster Bracelet and Clasp: Comfort and Security

The Rolex 216570 is fitted with the robust and comfortable Oyster bracelet, crafted from Oystersteel. This three-link bracelet is known for its durability and versatility.

• Oysterlock Clasp: The bracelet features the Oysterlock safety clasp, preventing accidental opening. It also includes the Easylink comfort extension system, allowing for tool-free adjustment of approximately 5mm, ideal for accommodating wrist size changes due to temperature or activity.
• Solid End Links: The bracelet integrates seamlessly with the case thanks to solid end links, enhancing the overall robustness and premium feel of the watch.
• Brushed Finish: The bracelet features a brushed finish, complementing the case and contributing to the watch's tool-watch aesthetic.

Functionality and Utility: More Than Just a Pretty Face

The Rolex 216570 is designed for practical use in demanding environments. Its features are not just for show; they serve a purpose for explorers, adventurers, and anyone who appreciates a reliable and functional timepiece.

• GMT Function: The ability to track a second time zone is invaluable for travelers and those who need to communicate across different time zones.
• 24-Hour Bezel: Beyond GMT functionality, the 24-hour bezel can be used as a rough timer or to simply provide a clear indication of AM/PM in situations where it's not readily apparent.
• Exceptional Legibility: The combination of the Chromalight display, Maxi hands, and clear dial layout ensures excellent legibility in all lighting conditions, from bright sunlight to complete darkness.
• Robustness and Durability: The Oyster case, Oystersteel construction, Parachrom hairspring, and Paraflex shock absorbers contribute to the watch's exceptional robustness and ability to withstand harsh conditions.
• Water Resistance: The Rolex 216570 is water-resistant to 100 meters (330 feet), making it suitable for swimming and everyday water activities.

Why the Rolex 216570 Remains a Desirable Timepiece

Despite being discontinued in 2021 and replaced by the reference 226570, the Rolex 216570 remains incredibly popular and highly sought after in the pre-owned market. Several factors contribute to its enduring appeal.

Modern Proportions and Wearability

The 42mm case size of the 216570 is considered by many to be the sweet spot for modern sport watches. It offers a substantial wrist presence without being overly large or cumbersome. It wears comfortably on a variety of wrist sizes and feels balanced and well-proportioned.

Enhanced Legibility and Functionality

The improvements in legibility compared to previous Explorer II models are significant. The Maxi hands, Chromalight display, and larger dial make time-telling effortless in any situation. The robust caliber 3187 movement provides reliable GMT functionality and peace of mind.

The "Polar" Dial's Allure

The white "Polar" dial version of the 216570 has become particularly iconic. Its clean, crisp aesthetic and striking contrast with the black indices and orange hand make it visually captivating and highly desirable. It's a distinctive and recognizable Rolex sports watch.

Investment Potential and Market Value

Rolex watches, in general, are known for holding their value well, and the Rolex 216570 is no exception. Due to its discontinuation and enduring popularity, pre-owned prices for the 216570 have remained strong and even appreciated in some cases. While watch values can fluctuate, the 216570 is often considered a relatively safe and potentially appreciating asset in the luxury watch market. (Note: Watch investment carries risk, and past performance is not indicative of future results. Consult with a financial advisor before making investment decisions.)

A Versatile Everyday Watch

Despite its tool-watch origins, the Rolex 216570 is surprisingly versatile. It can be dressed up or down, pairing equally well with casual attire or more formal settings. Its robust construction and timeless design make it a reliable and stylish companion for everyday wear.

Caring for Your Rolex Explorer II 216570

To ensure your Rolex 216570 continues to perform flawlessly and retain its value, proper care and maintenance are essential.

Regular Cleaning and Maintenance

Regularly cleaning your 216570 will help maintain its appearance and prevent the buildup of dirt and grime. Use a soft, damp cloth to gently wipe down the case and bracelet. You can also use a mild soapy water solution for a more thorough cleaning, ensuring you rinse and dry the watch completely afterwards. Avoid using harsh chemicals or abrasive cleaners.

Professional Servicing

Rolex recommends a full service of your watch approximately every 5-10 years, depending on usage and environmental conditions. Professional servicing should be performed by an authorized Rolex service center. This service includes a complete disassembly, cleaning, lubrication, and reassembly of the movement, as well as replacement of any worn parts and polishing of the case and bracelet if desired.

Storage and Handling

When not wearing your 216570, store it in a safe and dry place, preferably in its original Rolex box or a watch box. Avoid exposing the watch to extreme temperatures, strong magnetic fields, or direct sunlight for extended periods. Handle your watch with care to prevent scratches and impacts.

Buying a Rolex Explorer II 216570: Navigating the Market

Since the Rolex 216570 is discontinued, purchasing one typically involves the pre-owned market. Here's what you need to consider when buying a 216570.

Authorized Dealers vs. Grey Market/Pre-owned

You will no longer find new Rolex 216570 models at authorized Rolex dealers (ADs). Your primary options are:

• Reputable Pre-owned Dealers: Seek out established and reputable pre-owned watch dealers specializing in luxury watches. These dealers often offer certified pre-owned watches that have been inspected for authenticity and condition.
• Private Sales: Private sales can sometimes offer good deals, but they come with higher risk. Exercise caution and ensure you can verify the watch's authenticity and condition before purchasing.
• Online Marketplaces: Online marketplaces can be a source for pre-owned 216570 models, but due diligence is crucial. Buy from trusted sellers with positive reviews and consider using escrow services for added security.

Things to Consider When Buying Pre-owned

• Authenticity: Verify the watch's authenticity. Look for correct hallmarks, engravings, and movement details. If possible, have the watch authenticated by a professional watchmaker.
• Condition: Assess the watch's condition carefully. Check for scratches, dents, and wear on the case, bracelet, and crystal. Inquire about the watch's service history.
• Box and Papers: Ideally, purchase a 216570 with its original box and papers (warranty card, booklets). While not essential for authenticity, they add to the watch's value and provenance.
• Price: Research current market prices for pre-owned Rolex 216570 models in comparable condition. Compare prices from different sources to ensure you are getting a fair deal.
