The Complete Guide to GMT Watches: History, Types, and Best Picks for 2026
The GMT watch is a bonafide product of the jet age. While examples of dual-time watches date back to the 19th century, it was the advent of jet-powered commercial aircraft in the 1950s that drove the creation of this iconic complication. Today, GMT watches remain the ultimate travel companion for anyone crossing time zones.
The Origins: Pan-Am and Rolex
The most well-known GMT watch is the Rolex GMT Master, introduced in 1955 in collaboration with Pan-American World Airways. Designed for Pan-Am pilots, the watch allowed them to maintain a reference for Greenwich Mean Time (UTC/Zulu Time) while tracking local time. This collaboration resulted in the most recognizable colorway in dual-time watches: Pan-Am's iconic blue and red "Pepsi" bezel.
Another pioneer was Glycine's Airman, first introduced in 1953. Popular with American military pilots who could purchase the Swiss timepiece at their base exchange, the Airman solved the multiple time zone problem through a 24-hour main dial with a rotating 24-hour bezel. The watch even left Earth's atmosphere when Charles "Pete" Conrad wore an Airman on Gemini V and XI missions in 1965 and 1966.

The Second Golden Age of GMT Watches
In recent years, the GMT complication has entered its second golden age thanks to the introduction of new movements that have democratized this once-premium feature. Seiko and Citizen have launched both caller and traveler movements that smaller brands have eagerly adopted in their own globetrotting timepieces.
From Elliot Brown's Holton Auto GMT to Bulova's Oceanographer GMT, the GMT has become accessible to a wider audience than ever before. This democratization means that travelers no longer need to spend thousands of dollars to own a reliable dual-timezone watch.
