1. What is a GMT watch?
A GMT watch is a timepiece that allows you to tell the time in two different time zones.
It is the perfect watch for someone who travels a lot. Such as a pilot.
A GMT watch is able to track two time zones on a 24-hour scale. This gives pilots their local time, as well as a GMT reference (or as we know say UTC reference).
From this reference pilots can then use the watch to tell the time zone of any other city. Once they know how many hours to add or to subtract from GMT.
2. What does GMT stand for in a watch?
GMT stands for Greenwich Mean Time. GMT refers to that specific timezone. It’s the timezone of London, Dublin, and all the other cities within that timezone.
You can see the GMT timezone on the map, along with all the other current time zones of the world.
3. Why is UTC not GMT?
GMT is often confused with UTC.
UTC stands for Coordinated Universal Time, and replaced GMT as a more accurate and scientific measurement of time.
UTC differs from GMT due to the 24-hour system, which starts the counting from midnight.
However, there is no (meaningful) difference in time between GMT and UTC. If it’s 10am at GMT, then it’s 10am at UTC.
GMT has been relegated to just a timezone now.
4. How does a GMT watch work?
A GMT watch works by giving the wearer two time zones at any one time. Also offering the wearer the ability to check other time zones around the world too.
You first set the watch to your local time using the GMT watch’s main hands on the dial.
Then you use the extra GMT hour hand, and set that hand to the GMT timezone.
This extra GMT hour hand means you always know the GMT time, all the time.
Then when the GMT hand is used in conjunction with the 24 hour bezel. You can check the timezone of anywhere in the world. Once you know how many hours to add or subtract from the GMT time.

Pilots and adventurers were the first users of GMT watches. Today many business people and world travelers use GMT watches to keep track of the time in our super interconnected world.
7. Do I need a GMT watch?
If you travel a lot, and find yourself constantly changing to different time zones. Then a GMT watch should come in handy and might be a good investment.
However, no one really needs a GMT watch nowadays in a world that is powered by technology.
They were a necessity of the past. But nowadays most of us keep track of different time zones with our smartphones.
8. Who made the first GMT watch?
The first GMT watch is a contentious issue.
However, the Glycine Airman was released in 1953. This GMT watch was built for commercial pilots to use. A truly innovative timepiece from the Swiss watchmaker.
Glycine understood that pilots needed to know two time zones. They needed a watch that could tell this to them at the same time.
The new Airman could do both, making a commercial pilots job that little bit easier from 1953.
The Rolex GMT-Master is still considered by many to be the first and best GMT watch around.
However, Rolex released their first GMT watch in 1954. One year after the Glycine Airman was released.
9. What is the best GMT watch?
The most famous, and what many consider the most revolutionary GMT watch, is the Rolex GMT-Master.
The Rolex GMT-Master (Ref. 6542) was released in 1954. It was a watch specifically designed for pilots.
It had an automatic movement, the calibre 1036 that was fitted with a GMT complication.
The Rolex GMT-Master came from the collaboration with Pan-Am. Who was the US’s leading international airline at the time.
Pan-Am needed a watch that their pilots could use in order to read the time of two time zones at once.
This watch coincided with the revolution of the airline industry, and the huge growth in popularity of commercial flights.
Not much has changed with the original Rolex GMT-Master and the modern day Rolex GMT-Master II. As you can see from the two different advertisements from Rolex Magazine.
The Rolex GMT-Master is still loved by pilots, and now also loved by world travelers worldwide. Many consider the Rolex GMT-Master II the best GMT watch you can own.
