What Does GMT Mean?
GMT stands for Greenwich Mean Time, the time zone chosen as the “zero point” when the global time zone system was introduced in 1884. Although UTC (Universal Time Coordinated) is officially used today, the term GMT remains widely used in the watch world.
How Can You Recognize a GMT Watch?
It features an extra hour hand (often in a contrasting color, such as red) that shows a 24-hour time.
This hand makes one full rotation every 24 hours – half the speed of the regular hour hand.
The watch often has a rotating bezel marked in 24 hours – used to set a third time zone.
How to Use the GMT Function?
Example: You travel from Frankfurt to Sydney and want to keep track of German, Australian, and U.S. time.
- Set the GMT hand to German time (e.g., 12:00).
- Set the regular hour hand to local time in Sydney (e.g., 20:00).
- Rotate the bezel to correspond with New York time (e.g., 06:00).
Now you can instantly read all three times directly from the watch – no mental math required.
Why Do GMT Watches Exist?
The GMT function was invented to solve time zone issues, particularly for aviation and international travel.
In the past, different regions had their own local times, which caused chaos – especially when trains appeared. Once a global time zone system was introduced, GMT watches became a popular tool for quickly keeping track of multiple time zones.
Why Do You Need a GMT Watch?
In a world where travel and global communication are everyday realities, a GMT watch is a simple way to:
- Avoid converting time differences.
- Always keep track of home time, local time, and a third location (e.g., business partner, family).
- Enjoy function and elegance in one watch.
