The Rolex Explorer II, a watch synonymous with exploration and rugged durability, has undergone a significant evolution with the introduction of the reference 226570. This update, beyond the subtle aesthetic changes, boasts a completely new movement: the Caliber 3286. This article delves deep into the differences between the previous generation, the 216570 with its Caliber 3187, and the current model, highlighting the advancements offered by the 3286 and providing a comprehensive review of the new Rolex Explorer II. We'll also explore common queries surrounding the watch, including potential problems, hands-on experiences, and a detailed look at its dimensions.
What are the main differences between the Rolex Explorer II 216570 and 226570?
The most significant difference, and the core of this article, is the movement. The 216570 houses the Caliber 3187, a workhorse movement known for its reliability and accuracy. However, the 226570’s Caliber 3286 represents a quantum leap in Rolex’s in-house manufacturing capabilities. This isn't simply a minor upgrade; it's a complete redesign incorporating numerous improvements that significantly enhance performance and longevity. Beyond the movement, other key distinctions include:
* Power Reserve: The 3187 offers a 48-hour power reserve, sufficient for most users. The 3286, however, boasts a significantly extended 70-hour power reserve. This is a crucial advantage, particularly for those who might occasionally leave their watch unworn for a period. The extended power reserve allows for more flexibility and eliminates the worry of the watch stopping unexpectedly.
* Movement Architecture: The 3286 incorporates Rolex's latest advancements in Chronergy escapement, a silicon escape wheel that offers greater efficiency and resistance to shocks and magnetic fields. This contributes to the increased power reserve and improved accuracy. The 3187, while robust, lacks these features.
* Improved Anti-magnetic Properties: The use of silicon in the Chronergy escapement and other advancements in the 3286 significantly enhance the movement's resistance to magnetic fields. Modern life exposes watches to increasing levels of magnetism, and the 3286 is better equipped to withstand these environmental factors.
* Paramagnetic Hairspring: The 3286 utilizes a paramagnetic hairspring, further enhancing its resistance to magnetic fields and improving its isochronism (consistent timekeeping across different positions). This contributes to superior accuracy and long-term reliability.
* Finishing: While both movements are beautifully finished, the 3286 showcases Rolex's refined approach to detail, with more intricate and visually appealing finishing techniques.
* Bracelet and Case: While the overall design remains similar, subtle differences exist in the case and bracelet. The 226570 might feature slightly adjusted lug-to-lug dimensions or a refined bracelet construction, though these are often minor variations.
