A GMT watch is a wearable gadget that can keep track of two time zones simultaneously. It is a valuable tool for anyone who regularly travels between two time zones or who often needs to know the time in multiple time zones. 

GMT stands for Greenwich Mean Time, which is the mean solar time at the Royal Observatory in Greenwich, London. GMT time scale is the solar time at 0° longitude, where the Prime Meridian is located. 

In short, this can keep track of Greenwich Mean Times well as the local time. Read on to learn more about a GMT watch and how it works.

What is a GMT watch?

GMT watches display two or more time zones. The most popular type of GMT watch is the dual time zone watch, which has a central dial displaying the local time and a smaller dial showing the time in another time zone. 

Traditional GMT watches typically have 24-hour hands, which can be used to quickly and easily read the time in multiple time zones. But the modern wrist ones have 12 hands with a bezel of 24-hour reading indication. 

These watches also often have a bezel that can rotate, tracking the time in different time zones.

The time zone’s name was GMT before its establishment in 1972. The current UTC time zone is also sometimes referred to as GMT. Throughout the world, time and clocks are regulated by Coordinated Universal Time.

History of the GMT Watch

GMT watches have a long and exciting history. They were first developed in the early 20th century for use by pilots and sailors who had to keep track of time in multiple time zones. The GMT hand was added to watches in the 1950s.

British marines were used to keep a chronometer on GMT so that they could calculate their longitude from the Greenwich meridian. It was adopted internationally in 1884. Soon the usage combines with Nevil Maskelyn’s lunar distance method. 

As a result, GMT watches are being used worldwide to learn the standard time independent of location. Many countries legally adopted the Greenwich Mean Time throughout Great Britain, Jersey, Ireland, Guernsey, and so on.

How does the GMT watch Work?

GMT Watches are a popular type of watch that uses Coordinated Universal Time (CUT). When purchasing a GMT watch, one must know a couple of things and how it works.

Typically, a standard wristwatch has a 12-hour time interval, and the hour hand travels twice a day around the dial. On the contrary, a GMT watch features two different hour hands in different colors and shapes. 

The hand of the GMT watch travels one time around the dial, and the 24-hour bezel references it. So the looks of GMT watches are entirely unique from the standard watches. That’s why they are typically more expensive than other types of watches, making them valuable for people with multiple time zones to keep track of.

For example, you know that the UK is 5 hours ahead of the USA. If you have moved from California to London, you can still track the time zone back of your home with a GMT watch. Actually, things get complicated when you need to stay for a long-distance relationship. 

In this situation, you can adjust the GMT hour hand to your fixed place and the primary one according to your current location. Moreover, you can rotate the bezel and track the time of the West Coast with a minor adjustment. 

How to read GMT Watches?

GMT watches are an invaluable tool for both professional and recreational watch enthusiasts. These timepieces are a great way to keep track of time, but they can be tricky to use correctly. By understanding how to read GMT watches, you can get an accurate reading of the time, even in the most challenging of circumstances.     

The reading of GMT watches requires a few considerations. GMT watch calculates the number of hours ahead or behind GMT. So while reading the dial, you need to make some adjustments.  

Step 1: The first is to keep in mind the time zone in which the watch is being used because it uses a different time zone than your local time. So when you are wearing your GMT watch, the time will be different depending on where you are in the world.

For example, if you are in New York City and looking at your GMT watch, the time on your watch will be different than if you were in Los Angeles. It is essential to be aware of this to set your watch correctly and avoid confusion.

So, it would be best to determine how many times you are ahead or behind the time zone from the local time. 

Step 2: Adjust the bezel by rotating the number of hours and setting the second time zone. If you rotate the bezel to the left, then the second zone will be ahead of your local time. On the contrary, if you turn the bezel right, the time zone will go behind your local time. 

Step 3: One more thing to remember is that GMT watches will be around once a day. So you may have confusion determining AM/PM. However, the color combination on bezel helps to specify night and daytime quickly. Reading the watch is not so complicated. You just need to be used to it.
