To mark the 50th anniversary of its iconic Explorer II, Rolex has unveiled a significantly updated model. While retaining the rugged spirit and unmistakable design cues that have defined the watch for decades, this latest iteration boasts a brand-new movement, the caliber 3235, and subtle yet impactful design refinements. This article delves deep into the intricacies of this new movement, comparing it to its predecessors and exploring its place within the broader context of Rolex's horological advancements. While the article title mentions the "3137" movement, this is incorrect; the new Explorer II uses the caliber 3235. This clarification is crucial for accurate information.
The Explorer II, originally conceived as a tool watch for spelunkers and explorers needing to discern time in low-light conditions, has always been a testament to Rolex's commitment to robustness and precision. The introduction of the caliber 3235 signifies a continuation of this legacy, pushing the boundaries of performance and reliability. This article will avoid the misleading reference to a "3137" movement and instead focus on the accurate caliber 3235, providing a comprehensive analysis of its features and capabilities.
Beyond the 3137 Myth: Understanding the Caliber 3235
The erroneous mention of a "3137" movement highlights a common misunderstanding surrounding Rolex's nomenclature and model updates. Rolex's internal naming conventions aren't always immediately transparent to the public, leading to speculation and sometimes inaccurate information. The new Explorer II, however, unequivocally uses the caliber 3235, a movement that represents a significant step forward in Rolex's manufacturing prowess.
The caliber 3235 builds upon the success of previous generations of Rolex movements, incorporating several key improvements:
* Chronometer Certification: Like its predecessors, the 3235 is a COSC-certified chronometer, guaranteeing exceptional accuracy within specified tolerances. This rigorous testing process ensures that each movement meets the highest standards of precision.
* Enhanced Power Reserve: One of the most significant improvements is the extended power reserve. While the exact figures vary slightly depending on the specific model, the 3235 offers a power reserve of approximately 70 hours, significantly surpassing the power reserve of many of its predecessors. This extended power reserve is a crucial feature for adventurers and explorers who may not have access to regular winding.
* Paramagnetic Blue Parachrom Hairspring: The 3235 incorporates Rolex's patented Paramagnetic blue Parachrom hairspring, which is significantly more resistant to magnetic fields than traditional hairsprings. This is a vital feature in today's world, where electronic devices and magnetic fields are increasingly prevalent.
* Optimized Efficiency: Rolex has focused on optimizing the efficiency of the 3235, resulting in improved performance and longer-lasting power. This is achieved through meticulous design and manufacturing processes, reflecting Rolex's unwavering dedication to quality.
* Improved Shock Resistance: The movement also benefits from enhanced shock resistance, further bolstering its robustness and reliability in challenging environments.
