Question
Answer and Explanation
A GMT watch, or Greenwich Mean Time watch, is a timepiece designed to display the time in two or more different time zones simultaneously. It's an invaluable tool for travelers, pilots, and anyone who frequently needs to keep track of time in multiple locations around the world.
The key feature of a GMT watch is the presence of a 24-hour hand, often distinguished by a different color, and a rotating bezel marked with 24-hour numerals. The 24-hour hand indicates the time on the bezel, allowing you to easily read the time in a second time zone. Some advanced GMT watches can even display the time in a third time zone.
Originally developed for Pan American Airways pilots in the 1950s to help track time across various long-haul flight routes, the GMT watch has become an iconic and highly practical piece of horological engineering. Today, various brands offer GMT watches that combine function, durability, and style.
