The Legacy of Exploration: Understanding the Explorer II Lineage

To truly appreciate the Explorer II 216570, it's crucial to understand its historical context. The Rolex Explorer family was born from the brand's close association with exploration and adventure. The original Explorer, Ref. 6350, emerged in the early 1950s, drawing inspiration from the successful ascent of Mount Everest by Sir Edmund Hillary and Tenzing Norgay, equipped with Rolex Oyster Perpetuals. This spirit of resilience and precision in extreme conditions became the cornerstone of the Explorer line.

The Explorer II, first introduced in 1971 with the Ref. 1655, was a further evolution, specifically designed for speleologists and polar explorers who operate in environments where distinguishing day from night can be challenging. The key differentiator was the addition of a fixed 24-hour bezel and a dedicated 24-hour hand, providing a crucial reference point in disorienting conditions. Subsequent iterations, including the 16550 and 16570, refined the design and movement, paving the way for the impactful arrival of the 216570.

Rolex Explorer II 216570: A Modern Interpretation of a Classic

The Rolex Explorer II 216570 marked a significant departure in terms of size and design compared to its predecessors. Released to commemorate the 40th anniversary of the Explorer II, it was a bolder, more contemporary take on the iconic tool watch. Here’s a detailed breakdown of its key features:

Design and Aesthetics: Boldness and Legibility

One of the most immediately noticeable changes with the 216570 was its increased case size. Moving from the 40mm case of the 16570 to a robust 42mm, the 216570 offered a more substantial wrist presence, aligning with the trend towards larger watches at the time. This larger case size wasn't just for aesthetics; it enhanced legibility, a critical factor for a watch designed for demanding environments.

The dial of the Explorer II 216570 is available in two iconic variations: black and white (often referred to as "polar"). Both dials are designed for maximum readability, featuring:

• Maxi Dial: Larger hour markers and hands filled with Chromalight luminescent material provide exceptional low-light visibility. The blue glow of Chromalight is a signature Rolex feature, offering long-lasting luminescence.
• "Orange Hand": Perhaps the most distinctive design element is the oversized orange 24-hour hand. This vibrant color pays homage to the original Explorer II 1655 and adds a touch of vintage charm while significantly improving the visibility of the GMT function.
• Fixed 24-Hour Bezel: Crafted from stainless steel, the fixed bezel is engraved with 24-hour graduations, providing a quick and intuitive way to track a second time zone when used in conjunction with the orange 24-hour hand.
• Oyster Case: The 904L stainless steel Oyster case, synonymous with Rolex durability, ensures water resistance to 100 meters (330 feet). This robust construction protects the precise movement within from the elements.

Functionality and Features: Built for Exploration

Beyond its striking aesthetics, the Explorer II 216570 is a highly functional tool watch. Its core features are geared towards practical utility:

• GMT Function (Second Time Zone): The 24-hour hand, in conjunction with the fixed bezel, allows the wearer to track a second time zone. This is invaluable for travelers, pilots, and anyone needing to monitor time in different locations.
• Date Function: A magnified date window at 3 o'clock, enhanced by the Cyclops lens, provides quick and easy date readability.
• Chronometer Certification: The Explorer II 216570 is a Superlative Chronometer, officially certified by the COSC (Contrôle Officiel Suisse des Chronomètres). This certification guarantees exceptional precision and reliability, exceeding industry standards. Rolex further tests its movements in-house after COSC certification to ensure even higher levels of performance.
• Paraflex Shock Absorbers: Rolex's high-performance Paraflex shock absorbers offer increased resistance to shocks and impacts, crucial for a watch designed for adventurous activities.
• Parachrom Hairspring: The paramagnetic blue Parachrom hairspring is resistant to magnetic fields and temperature variations, further enhancing the movement's accuracy and stability.

The Heart of the Explorer II 216570: Caliber 3187

Powering the Rolex Explorer II 216570 is the Caliber 3187, a robust and reliable self-winding mechanical movement entirely developed and manufactured by Rolex. This movement is specifically designed for GMT functionality and incorporates several key Rolex innovations:

• Perpetual Rotor: The self-winding mechanism is powered by Rolex's Perpetual rotor, ensuring efficient and continuous winding of the mainspring with the natural movements of the wearer's wrist.
• 31 Jewels: Utilizing 31 jewels, the movement minimizes friction and wear, contributing to its longevity and accuracy.
• Approximately 48-Hour Power Reserve: When fully wound, the Caliber 3187 offers a power reserve of approximately 48 hours, meaning the watch will continue to run for about two days even when not worn.

Why the Explorer II 216570 Remains Highly Desirable

Despite being discontinued in 2021 in favor of the updated 226570, the Explorer II 216570 remains incredibly popular and sought after in the pre-owned market. Several factors contribute to its enduring appeal:

• Modern Classic Design: The 216570 successfully blends classic Explorer II elements with a contemporary design language. Its larger size, bold hands, and orange accents make it a visually striking and recognizable Rolex.
• Enhanced Functionality: The GMT function, combined with Rolex's legendary reliability and robustness, makes it a highly practical and versatile watch for everyday wear and travel.
• Investment Potential: Rolex watches, in general, tend to hold their value well, and the Explorer II 216570 is no exception. Due to its discontinuation and desirability, prices in the pre-owned market have often seen appreciation, making it a potentially sound investment.
• Limited Production Run: While produced for a decade, the 216570 is now out of production, adding to its collectibility and desirability among enthusiasts.
• "Last of an Era": Some collectors see the 216570 as the "last of an era" before Rolex fully transitioned to their newer generation movements and design language in subsequent Explorer II models.

Buying a Rolex Explorer II 216570: What to Consider

If you are considering purchasing a Rolex Explorer II 216570, here are some key factors to keep in mind:

• Authenticity: Due to Rolex's popularity and value, counterfeits are prevalent. Always purchase from reputable dealers or authorized pre-owned retailers. Thoroughly inspect the watch and paperwork, and consider having it authenticated by a Rolex service center if you have any doubts.
• Condition: The condition of the watch significantly impacts its value. Assess the case, bracelet, crystal, and movement for any signs of wear or damage. Watches in excellent condition with original box and papers ("full set") command higher prices.
• Market Price: Research current market prices from reputable online marketplaces and dealers to understand fair value. Prices can fluctuate based on condition, box/papers, and market demand.
• "Polar" vs. Black Dial: Both dial variations are desirable, but the "polar" (white) dial is often perceived as slightly more sought-after and may command a premium. Personal preference should be a key factor in your decision.
• Service History: Inquire about the watch's service history. A recently serviced watch from Rolex or a reputable watchmaker can provide peace of mind.

Explorer II 216570 vs. Newer 226570: Key Differences

The successor to the 216570, the Explorer II 226570, introduced in 2021, features several notable updates:

• Movement Upgrade: The 226570 is powered by the Caliber 3285, a newer generation movement with improved efficiency, a longer power reserve (approximately 70 hours), and enhanced shock resistance.
• Slight Case Refinements: While still 42mm, the 226570 features slightly refined case proportions, with a slimmer profile and more sculpted lugs in the eyes of some observers.
• Bracelet Update: The bracelet on the 226570 may have subtle refinements in its links and clasp.
• Crown Guards: Some subtle differences in the crown guards may be present.

Ultimately, both the 216570 and 226570 are exceptional watches. The choice between them often comes down to personal preference, budget, and whether the updated movement and subtle design changes of the 226570 justify the potentially higher price point of newer models. Many appreciate the 216570 for its robust feel and classic design that firmly established the modern Explorer II aesthetic.
