The Rolex GMT-Master II is a legendary watch, instantly recognizable for its iconic bezel and versatile functionality. Among its various iterations, the 2019 model, reference 126710BLNR, stands out for its updated movement and the introduction of the Jubilee bracelet to the "Batman" variant. This article will delve into the specific dimensions of this particular model, focusing on its thickness, while also exploring related aspects like its price, movement, bezel, size, and the broader context of the GMT-Master II line, including the popular Pepsi and Jubilee bracelet options.
The 126710BLNR: Dimensions and Feel
The Rolex GMT-Master II 126710BLNR boasts a diameter of 40mm, a size that has become a standard for many modern sports watches. However, it's the 12mm thickness that often sparks discussion. While 12mm isn't excessively thick for a watch with its features and robust construction, it represents a notable difference compared to some other Rolex models and, specifically, its predecessors using the Oyster bracelet. The subjective experience of "thickness" is also influenced by the case design and the way the watch sits on the wrist.
Many owners and reviewers comment that the 126710BLNR, despite its 12mm height, feels slimmer on the wrist than its Oyster bracelet-equipped predecessors. This perceived difference is attributed to several factors. The Jubilee bracelet, known for its five-piece links and flexible design, conforms more closely to the wrist than the more rigid Oyster bracelet. This creates a more comfortable and less bulky feel, mitigating the impact of the 12mm height. The subtle differences in case design between generations of the GMT-Master II also play a role, with the 126710BLNR exhibiting a more streamlined profile.
The 12mm thickness is a result of incorporating the new Calibre 3285 movement, a significant upgrade over its predecessor. This movement, discussed in detail below, offers improved accuracy, power reserve, and overall performance. The extra space required for this sophisticated mechanism contributes to the watch's overall height. This highlights a common trade-off in watchmaking: advanced technology often requires more space within the case.
Rolex GMT-Master II Movement: The Calibre 3285
The heart of the 126710BLNR is the Calibre 3285, a self-winding mechanical movement entirely developed and manufactured by Rolex. This movement represents a significant leap forward in Rolex's watchmaking capabilities. Compared to the previous generation movements, the Calibre 3285 offers:
* Enhanced Chronometric Performance: Featuring a higher frequency (28,800 vibrations per hour) and a paramagnetic blue Parachrom hairspring, the Calibre 3285 boasts exceptional precision and resistance to magnetic fields. This contributes to the watch's superior timekeeping accuracy.
* Increased Power Reserve: The Calibre 3285 provides a power reserve of approximately 70 hours, a significant improvement over previous movements. This allows for more convenient timekeeping, particularly when the watch is not worn for extended periods.
