THE difference between a GMT and a True GMT

A GMT watch is a special kind of watch that helps you track time in two places at once. “GMT” stands for “Greenwich Mean Time,” which is a time standard used around the world. These watches have an extra hand and a special 24-hour scale or bezel to show a second time zone.

How Does a GMT Watch Work?

A GMT watch has an extra hand that moves around the dial once every 24 hours. This hand points to a second time zone on the 24-hour scale or a rotating bezel. This means you can check the local time while also keeping track the time in another country.

What is the Difference Between a Standard GMT and a True GMT?

There are two types of GMT watches Standard GMT Office GMT) watches and True GMT (Travel GMT) watches. The difference is in how the hour hand works when setting the time.

Standard GMT (Office GMT)

The GMT hand moves separately from the main hour hand.

The local time hour hand does not move on its own; you have to adjust all the hands together.

Best for people who work with different time zones but don’t travel much.

Examples left to right : Traser H3 P68 Pathfinder GMT, Spinnaker Fleuss GMT.

True GMT (Travel GMT)

The local time hour hand moves separately in one-hour steps without stopping the watch.

Great for travellers because you can easily set the local time without affecting the second time zone.

Best for frequent flyers and those who change time zones often.

Examples: Bulova Oceanographer GMT

Which GMT Watch Should You Choose?

If you travel a lot, a True GMT is the best choice.

If you are a desk diver that doesn’t travel a lot but still wants the GMT function, a Standard GMT is good enough and is usually less expensive.
