The Rolex Explorer II reference 216570, affectionately known by many as the "216570" or simply the "Exp II," holds a special place in the hearts of watch enthusiasts. This robust and reliable tool watch, produced from 2011 to 2021, represents a pinnacle of horological engineering and design, built for exploration and everyday wear. This article will delve into the intricacies of this iconic timepiece, covering everything from its precise manual winding and date setting procedures to a comprehensive review of its features, comparing it to its successor, and exploring its place within the broader Rolex Explorer II lineage.
Setting the Time and Date: A Step-by-Step Guide
The 216570, powered by the Calibre 3187, is a self-winding mechanical movement, but it also allows for manual winding via the crown. Setting the time and date requires careful attention to the crown's positions:
1. Crown in Position 1 (First Notch): Carefully pull the crown out to the first notch. This position unlocks the time-setting mechanism.
2. Setting the Date: Turning the crown clockwise or counterclockwise will adjust the date. Note that the date changes instantaneously as the hour hand passes midnight. Attempting to change the date between 9 PM and 3 AM is generally discouraged to avoid potential damage to the movement.
3. Setting the Hour Hand: Turning the crown will move the hour hand in one-hour increments. The minute hand will move accordingly.
4. Crown in Position 0 (Fully Pushed In): Once the time and date are correctly set, gently push the crown back into its original position. This re-engages the winding mechanism and ensures the watch's water resistance. Always ensure the crown is fully screwed down before any exposure to water.
A Deep Dive into the Rolex Explorer II 216570 Review
The 216570 boasts several key features that contribute to its legendary status:
* Robust Oyster Case: The iconic Oyster case, known for its water resistance and durability, is a hallmark of Rolex. The 40mm case of the 216570 is perfectly sized for most wrists, offering a substantial presence without being overly bulky. The Triplock winding crown further enhances its water resistance, rated to 100 meters (330 feet).
* Calibre 3187 Movement: This in-house movement is a testament to Rolex's commitment to precision and reliability. It features a Paramagnetic blue Parachrom hairspring, offering superior resistance to magnetic fields and shocks. The movement’s robust construction ensures accuracy and longevity.
* Highly Legible Dial: The 216570's dial is designed for optimal readability in low-light conditions. Large, luminous hour markers and hands provide clear visibility, a crucial feature for its intended purpose as a tool watch for exploration. The distinct orange hand, indicating a second time zone, is a hallmark of the Explorer II.
* Durable Oyster Bracelet: The Oyster bracelet, with its solid links and secure clasp, provides exceptional comfort and durability. Its robust construction ensures the watch remains securely fastened, even during strenuous activities.
* Fixed Bezel: Unlike some other Rolex models, the 216570 features a fixed bezel, further enhancing its ruggedness and simplicity. The lack of a rotating bezel simplifies the design, making it less prone to damage.
