GMT-Master II

Introduction to the Rolex GMT-Master II

The Rolex GMT-Master II is one of the most iconic travel watches, designed specifically for pilots and global travelers.

The original GMT-Master was launched in 1955, developed at the request of Pan American World Airways (Pan Am) to provide its flight crews with a watch that could display two time zones simultaneously.

Key Features of the GMT-Master II:

• GMT Function (Dual Time Zone): This is the core feature. The watch has four hands: an hour hand, a minute hand, a seconds hand, and a fourth hand (usually with a triangular tip) that completes one full rotation every 24 hours. This 24-hour hand points to a second time zone (e.g., "home time") on the bezel.

• Bidirectional 24-Hour Bezel: The bezel is graduated with 24-hour markings. By rotating the bezel, the wearer can quickly read a third time zone.

• Two-Tone Cerachrom Bezel: The most recognizable feature of the GMT-Master II is its two-color Cerachrom ceramic bezel. Famous color combinations have their own "nicknames":

  • "Pepsi": Red and Blue (symbolizing day and night).

  • "Batman" / "Batgirl": Black and Blue.

  • "Sprite": Green and Black (a left-handed version).

• The "Master II" Difference: The GMT-Master II version (introduced in 1982) offered a crucial upgrade. It allows the main 12-hour hand to be adjusted independently (in one-hour "jumps," forwards or backward) without stopping the minute, second, or 24-hour hands. This makes it extremely fast for travelers to change their "local time" when they arrive in a new time zone, all while maintaining their "home time" on the GMT hand.

Thanks to its combination of superior functionality, robust design (waterproof Oyster case), and iconic aesthetics, the GMT-Master II has become one of the most desired sports watches in the world.
