The Rolex GMT-Master II is a legendary watch, renowned for its functionality, durability, and iconic design. While its 40mm diameter is frequently discussed, the thickness of the GMT-Master II is a crucial aspect often overlooked, impacting both its wearability and overall aesthetic. This article will explore the 12mm thickness of the reference 126710BLNR (and variations across other models), comparing it to other Rolex models and delving into the factors influencing its dimensions. We will also touch upon related topics such as Rolex Explorer II size, general Rolex watch size charts, bezel and lug dimensions, and even delve into the specific characteristics of the popular "Batman" GMT-Master II.
The 12mm Thickness of the Rolex GMT-Master II Reference 126710BLNR:
The Rolex GMT-Master II reference 126710BLNR, popularly known as the "Batman" due to its blue and black bezel, boasts a case thickness of 12mm. This measurement refers to the distance between the top of the crystal and the bottom of the caseback when the watch is laid flat. It's important to note that this is a relatively standard thickness for a modern sports watch of this size, particularly one with the robust build and features of the GMT-Master II. However, even within the GMT-Master II line, slight variations can exist depending on the specific reference number and year of production. Minor discrepancies may arise due to manufacturing tolerances and potentially even the addition of aftermarket modifications.
Factors Influencing GMT-Master II Thickness:
Several factors contribute to the 12mm thickness of the GMT-Master II:
* Movement: The calibre 3285 movement, used in the 126710BLNR, is a relatively thick automatic movement. This is necessary to accommodate its advanced features, including the robust construction, anti-magnetic shielding, and increased power reserve. More complex movements generally require more space.
* Case Construction: The robust oyster case, a hallmark of Rolex, contributes significantly to the overall thickness. This case is designed for durability and water resistance, featuring a solid caseback, screw-down crown, and Triplock winding system. These features add to the thickness but are essential for the watch's functionality and reliability.
* Crystal: The sapphire crystal, known for its scratch resistance, also adds to the overall height. While sapphire is relatively thin, it still contributes to the overall profile of the watch.
* Bezel: While the bezel itself doesn't directly add much thickness, the design and construction of the insert and its mechanism slightly influence the overall dimensions.
Comparing the GMT-Master II Thickness to Other Rolex Models:
Comparing the 12mm thickness of the GMT-Master II to other Rolex models provides valuable context. Let's briefly examine some examples:
* Rolex Explorer II Size Chart: The Rolex Explorer II, another popular sports watch, generally has a slightly thinner profile than the GMT-Master II, usually around 11mm to 12mm depending on the reference. This difference is partly due to the simpler movement used in the Explorer II.
