Historical Background of the Rolex GMT-Master Line

1. Origins of the GMT-Master (1955)

The GMT-Master was first introduced in 1955 as the reference 6542, designed for Pan American World Airways (Pan Am) pilots. The original purpose of the watch was to help pilots track two time zones simultaneously, especially important during the rise of international travel. The GMT-Master featured a 24-hour hand and a rotating bezel with a 24-hour scale, allowing the wearer to read the time in a second time zone.

2. Evolution to GMT-Master II (1983)

The GMT-Master II was introduced in 1983 with reference 16760, featuring an independent 24-hour hand that allowed the wearer to set a second time zone without adjusting the main hour hand. This increased functionality made it more versatile than the original GMT-Master, which was eventually phased out.

3. Ceramic Bezel Innovation (2007)

One of the key innovations in the GMT-Master II line was the introduction of the Cerachrom bezel in 2007. The ceramic bezel, known for its durability and scratch resistance, became a defining feature of the modern GMT-Master II watches. The two-tone ceramic bezels became especially popular, with notable models like the “Pepsi” (red and blue) and “Batman” (blue and black).

1. Introduction at Watches & Wonders 2023

The 126710GRNR was unveiled at the 2023 Watches & Wonders show, and it quickly garnered attention for its striking color combination and classic design. It became known for its two-tone bezel, featuring black and gray Cerachrom inserts, with the gold and black (GRNR) elements representing a bold yet sophisticated update to the GMT-Master II collection.

2. Key Features

• Bezel: The black and gray bezel is crafted from Rolex's proprietary Cerachrom ceramic, offering superior resistance to scratches and fading. The black portion represents nighttime hours, while the gray section denotes daytime hours, allowing the wearer to easily distinguish between day and night in a second time zone.

• Materials: The 126710GRNR is available in two primary variations:

  • Oystersteel and yellow gold (also referred to as Rolesor), combining durable stainless steel with luxurious 18k yellow gold.

  • A full 18k yellow gold model for those seeking a more opulent version of the watch.

• Dial: The watch features a classic black dial, with luminescent hour markers and hands that provide excellent legibility, even in low light. The 24-hour GMT hand is highlighted in gold, which complements the overall design and enhances the watch's aesthetic.

• Movement: The watch is powered by the Rolex Caliber 3285 movement, which has been a staple in the GMT-Master II collection since 2018. The Caliber 3285 offers high precision, shock resistance, and a 70-hour power reserve. It includes Rolex’s Chronergy escapement and a Parachrom hairspring, making it highly reliable and robust.

• Bracelet Options: The 126710GRNR is available with either a Jubilee or Oyster bracelet, offering different styling choices. The Jubilee bracelet provides a more elegant look with its five-piece link construction, while the Oyster bracelet offers a sportier, robust feel.

• Water Resistance: The case is equipped with Rolex's signature Triplock crown, giving the watch 100 meters of water resistance, making it highly practical for everyday wear as well as professional use.
