A Tool for the Skies — In 1955, Rolex unveiled the very first GMT-Master, reference 6542, created in collaboration with Pan American Airways to equip their pilots with a watch capable of tracking two time zones simultaneously. Its now-iconic red and blue bezel—later nicknamed the “Pepsi” by collectors—wasn’t just for style. The vibrant color split was originally intended to distinguish day from night at a glance, even in the dim confines of a cockpit.
By 1959, the 6542 was retired in favor of the reference 1675, which brought several updates, most notably the addition of crown guards. The GMT-Master line has been in continuous production ever since, evolving in design but always true to its dual-time heritage.
This particular reference 1675 dates to around 1968 and features the desirable matte “Long E” dial—known to collectors as the Mark 1 matte dial. Its nickname comes from the extended center crossbar on the “E” in “ROLEX,” which reaches the same length as the letter’s upper and lower arms. The Rolex coronet is also rendered in a distinctive, delicate “string-like” style unique to this dial variant.
While we appreciate the minutiae of dial typography, what makes this example truly special is its overall vintage appeal. The combination of the red-and-blue Pepsi bezel, the flat matte black dial, and the creamy patina of its lume creates a perfectly balanced look that defines a great vintage GMT. The red-and-blue bezel fitted here is a newer aftermarket replacement, offering a clean, vibrant take on the iconic “Pepsi” aesthetic.
Completing the package is the Rolex Jubilee bracelet, one of the most comfortable and elegant options the brand has ever offered. It’s a less common pairing on a GMT-Master, adding an extra layer of charm and distinction to the watch.
The GMT-Master remains one of Rolex’s most collectible models, and this example checks all the right boxes: character, patina, and timeless style. In the world of vintage Rolex, it’s the small, unique details that set one watch apart from another—and this 1675 is brimming with them.
