The Rolex GMT-Master II, a watch synonymous with global travel and adventure, has undergone significant advancements throughout its history. While retaining its iconic design and functionality, Rolex continually refines its inner workings, pushing the boundaries of horological precision and reliability. This article delves deep into the new movement powering many contemporary GMT-Master II models, exploring its capabilities, comparing it to previous iterations, and examining its place within the rich history of the GMT-Master line. We’ll also touch upon various aspects of the watch itself, including its bezel, size, and the differences between the GMT-Master and GMT-Master II.
The Heart of the Explorer: Calibre 3285
The current generation of GMT-Master II models are largely equipped with the calibre 3285 movement. This isn't simply an incremental update; it represents a significant leap forward in Rolex's commitment to chronometric excellence. Replacing its predecessor, the calibre 3186, the 3285 boasts numerous enhancements, all contributing to improved accuracy, robustness, and power reserve.
One of the most significant improvements is the incorporation of Rolex's Chronergy escapement. This silicon-based escapement offers superior efficiency and resistance to shocks and magnetic fields compared to traditional escapements. This translates to a more precise timekeeping performance, even under demanding conditions. The increased efficiency also contributes to a longer power reserve, a crucial feature for any traveller who might not have the opportunity to wind their watch regularly.
The calibre 3285 also benefits from Rolex's innovative Paraflex shock absorbers. These sophisticated shock absorbers further enhance the movement's resilience to impacts, protecting the delicate internal components from damage. This is particularly important for a watch designed to withstand the rigours of travel, where accidental bumps and knocks are inevitable.
Another key feature of the 3285 is its extended power reserve. Compared to the 3186, the 3285 provides approximately 70 hours of power reserve. This is a considerable improvement, allowing the wearer to remove the watch for a weekend or a short trip without the need for immediate rewinding upon return. This extended power reserve is a practical advantage, especially beneficial for frequent travellers whose schedules may not always allow for consistent winding.
Beyond these significant improvements, the calibre 3285 also incorporates Rolex's meticulous attention to detail and finishing. The movement is meticulously crafted, with each component exhibiting the high standards of quality synonymous with the Rolex brand. This dedication to precision ensures not only superior performance but also longevity, making the 3285 a movement built to last a lifetime.
Rolex GMT-Master II Movement: A Comparative Look
Understanding the advancements in the calibre 3285 requires a comparison with its predecessor, the calibre 3186. While the 3186 was itself a highly reliable movement, the 3285 offers tangible improvements. The enhanced power reserve, improved shock resistance, and superior efficiency of the Chronergy escapement set the 3285 apart. The increased resistance to magnetic fields is also a significant advantage in today's world, where electronic devices are ubiquitous.
The difference in performance between the two movements might not be immediately apparent in everyday use, but under rigorous testing and in challenging conditions, the superior performance of the 3285 becomes evident. This translates to a watch that is more reliable, more accurate, and more robust, making it the ideal companion for the discerning traveller.
