Hey watch enthusiasts! Today, we're diving deep into the world of Rolex Explorer II, comparing two iconic models: the 216570 and the 16570. If you're scratching your head trying to figure out which one deserves a spot on your wrist, you've come to the right place. We'll break down everything from their design and movement to what makes each of these watches a legend in its own right.

A Quick Look at the Rolex Explorer II Legacy

Before we get into the nitty-gritty, let's appreciate the Explorer II's background. The Rolex Explorer II was first introduced in 1971 with the reference 1655, designed as a tool watch for explorers, particularly speleologists (cave explorers). These guys needed a reliable watch that could distinguish between day and night in environments devoid of sunlight. Fast forward to today, and the Explorer II has evolved into a coveted sports watch, blending rugged functionality with Rolex's signature elegance. Knowing the historical context helps us understand why these watches are so special and why comparing the 216570 and 16570 is more than just a surface-level comparison; it’s about understanding the evolution of a tool watch icon.

Rolex Explorer II 16570: The Classic Refinement

The Rolex Explorer II 16570, produced from the late 1980s until 2011, represents a significant chapter in the Explorer II story. This model is often praised for its classic proportions and timeless design. Let's delve into what makes this watch tick:

Design and Features

• Case Size: The 16570 features a 40mm stainless steel case, a size considered versatile and comfortable for a wide range of wrist sizes. This diameter provides a balanced presence without being overly imposing, making it suitable for both casual and more formal settings.
• Dial Options: Available in both black and polar (white) dial options, the 16570 offers choices to suit different aesthetic preferences. The black dial provides a classic, sporty look, while the polar dial offers enhanced legibility and a distinctive, almost vintage appeal.
• Bezel: The fixed 24-hour bezel, a signature element of the Explorer II, is made of stainless steel and allows the wearer to track a second time zone when used in conjunction with the 24-hour hand. The engraved numerals on the bezel are crisp and clear, contributing to the watch's overall functionality and aesthetic.
• Bracelet: Typically paired with the Rolex Oyster bracelet, the 16570 offers a robust and secure fit. The Oyster bracelet is known for its durability and comfort, making it an excellent choice for everyday wear. The bracelet's design complements the overall aesthetic of the watch, adding to its sporty yet refined appearance.
• Crystal: The 16570 uses a sapphire crystal, which is highly scratch-resistant and provides excellent clarity. However, it sits slightly above the bezel, making it somewhat prone to chipping if subjected to hard impacts. This is a minor drawback but worth considering for those who lead particularly active lifestyles.

Movement

Inside the 16570, you'll find the Rolex Caliber 3185 or 3186 (depending on the production year). These movements are chronometer-certified, meaning they've undergone rigorous testing to ensure exceptional accuracy and reliability. The 3185 and 3186 movements are known for their robustness and longevity, making them a reliable choice for everyday wear. The key difference between the two is that the 3186, introduced later in the production run, features an updated hairspring and improved time-setting mechanism, enhancing its overall performance.

Why the 16570 Still Appeals

For many, the 16570 hits the sweet spot with its balanced proportions and classic design. It's a watch that feels at home whether you're scaling a mountain or attending a business meeting. Plus, its long production run means there are plenty of options available on the pre-owned market, often at more accessible price points compared to newer models. The 16570's enduring appeal lies in its ability to blend functionality with timeless elegance, making it a versatile and reliable companion for any adventure.

Rolex Explorer II 216570: The Modern Upgrade

Enter the Rolex Explorer II 216570, launched in 2011 to celebrate the 40th anniversary of the Explorer II. This model brought a bold new look and several modern upgrades to the iconic series. Let's see what sets it apart:

Design and Features

• Case Size: The most noticeable change is the increased case size, jumping to 42mm. This gives the 216570 a more substantial presence on the wrist, catering to the modern preference for larger watches. The increased size not only enhances its wrist presence but also improves legibility, making it easier to read the time and other functions at a glance.
• Dial and Hands: The 216570 also features larger hour markers and hands, coated with Chromalight for enhanced legibility in low-light conditions. The Chromalight lume emits a long-lasting blue glow, providing superior visibility compared to the green lume found on older models. The orange 24-hour hand is a nod to the original Explorer II 1655, adding a touch of vintage charm to the modern design.
• Bezel: The 24-hour bezel remains a key feature, but with a more contemporary font and bolder numerals for improved readability. The brushed finish of the bezel contrasts nicely with the polished case, adding to its overall aesthetic appeal. The bezel is also slightly wider than that of the 16570, further enhancing the watch's robust appearance.
• Bracelet: The bracelet on the 216570 is also more substantial, with wider links and a more robust clasp. This provides a more secure and comfortable fit, especially for those with larger wrists. The bracelet also features the Easylink comfort extension system, allowing the wearer to easily adjust the bracelet length by 5mm without the need for tools, providing added convenience and comfort.
• Crystal: Like the 16570, the 216570 uses a sapphire crystal for its scratch-resistant properties. However, the crystal on the 216570 is slightly more flush with the bezel, reducing the risk of chipping.

Movement

The 216570 houses the Rolex Caliber 3187, an evolution of the 3186. This movement includes a Parachrom hairspring, offering greater resistance to shocks and temperature variations. The Caliber 3187 also features improved efficiency, contributing to a longer power reserve. Like its predecessors, the 3187 is chronometer-certified, ensuring exceptional accuracy and reliability. The enhancements in the movement reflect Rolex's commitment to continuous improvement and innovation, making the 216570 a highly reliable and accurate timepiece.

Why the 216570 is a Modern Favorite

The 216570 appeals to those who prefer a larger, more modern sports watch. Its enhanced legibility, robust construction, and modern movement make it a top choice for adventurers and watch enthusiasts alike. The 216570 stands out with its bolder design and modern features, making it a favorite among those who appreciate contemporary aesthetics and advanced technology.

Head-to-Head Comparison: 216570 vs. 16570

Okay, let's get down to the specifics. Here's a side-by-side comparison to help you make a decision:
