The Rolex GMT-Master II is more than just a watch; it's a legend. Its iconic status is cemented not only by its sophisticated functionality but also by its rich history, inextricably linked to the pioneering spirit of aviation and exploration. In 1959, eight men from a British army regiment embarked on a round-the-world expedition, their wrists adorned with prototypes of the very watch that would later become a symbol of global travel and adventure: the Rolex GMT-Master. This article will delve into the waterproof capabilities of the GMT-Master II, exploring its specifications, various models and versions, and its enduring appeal in the context of its storied past. We'll also briefly touch upon related Rolex models for comparison.
GMT-Master II Waterproof: A Legacy of Reliability
The waterproof nature of the Rolex GMT-Master II is not a mere add-on; it's an integral part of its DNA, a testament to Rolex's unwavering commitment to quality and durability. From its inception, the GMT-Master was designed to withstand the rigors of long-distance flights and challenging environments. Modern GMT-Master II models boast impressive water resistance, typically rated at 100 meters (330 feet). This means the watch can handle splashes, rain, and even shallow water immersion without compromising its functionality. However, it's crucial to remember that this is not a diving watch; the Rolex Submariner holds that title. The GMT-Master II's water resistance is designed to protect it from accidental exposure to water, not prolonged underwater use.
This impressive water resistance is achieved through a combination of meticulous engineering and high-quality materials. The case, typically crafted from Oystersteel (a corrosion-resistant 904L stainless steel), provides a robust outer shell. The screw-down crown and caseback create a hermetic seal, preventing water from entering the movement. The sapphire crystal, renowned for its scratch resistance, also contributes to the watch's overall protection. Regular servicing by authorized Rolex technicians is crucial to maintain the watch's water resistance over time, ensuring the seals remain effective and preventing potential damage to the delicate internal mechanisms.
Rolex GMT-Master II Specs: A Detailed Examination
Understanding the specifications of the Rolex GMT-Master II provides a deeper appreciation for its engineering prowess and functionality. While specific details may vary slightly depending on the model and year of production, key features consistently highlight the watch's exceptional quality:
* Movement: The GMT-Master II is powered by a self-winding mechanical movement, typically a calibre 3186 or its successor, the calibre 3285. These movements are renowned for their accuracy, reliability, and power reserve (approximately 50 hours). The calibre 3285 features Rolex's Chronergy escapement, enhancing performance and resistance to shocks.
* Case Material: Predominantly crafted from Oystersteel, offering exceptional corrosion resistance and durability. Some models also feature variations in materials, including precious metals like yellow gold, white gold, or combinations of steel and gold.
* Case Diameter: The standard case diameter is typically 40mm, although some models, like the GMT-Master II Root Beer, feature a slightly larger 41mm case.
* Crystal: A scratch-resistant sapphire crystal protects the dial and ensures clear readability.
