You might had gone on a long trip, crossing several states, countries or continent. It won’t surprised me if You went swimming or diving in a nearby beach or hotel pool, and you though ‘eh, my watch shouldn’t get into water’. Probably, you wore the right watch during your entire journey, which could read time in multiple timezones, and perhaps, it failed to accompany you as a swimming or diving partner. With the best GMT dive watch, you could go snorkeling, fishing, sailing, swimming, and diving as you like it, and still be able to check international time accurately, even under the water.

Your flight ticket allows you board a plane or ship, but a good GMT travel watch allows you to check time and follow up even in multiple timezones. The perfect world time watch that permits you follow events in real-time, back in your home country, while on a vacation, is a GMT watch – a watch that reads time on a 24-hour scale.
my Phone tells time, why should I border spending hundreds, to thousands of dollars on another timer? Well, a GMT dive watch is more than just a local timekeeper. It has a dual time scale and tells both your local time and well as time in any other timezone on the earth, without you making any brain calculation. The best GMT watches are indispensable travel partners and they are rare to find the ones that double as ocean dive watches.
Just a little History of GMT watches
There is more on what is and how to read a GMT watch. Glycine, stunned the world when it unveiled the Airman in 1953 – a timepiece that kept time on a 24-hour scale . While the local time was displayed as usual on the dial, Airman used a rotating 24-hour bezel for tracking a second timezone.
Rolex looked deep into the future we have today, and realized more than just that. The same year, a standard was set and the Rolex GMT Master was born. The Rolex GMT master kept local time on the standard 12-hour scale and incorporated a 24-hour slowly-rotating fourth hand.
To copy from Airman, Rolex also integrated a rotating 24-hour bezel for users to track a second timezone. From then, wearer could read time in a different timezone(country) on the the fourth hand while still reading the current local time on a 12-hour scale.
As time when on, GMT watch manufacturers realized that an international, professional diver does not need to have separate watches – A GMT Watch and A Dive Watch. They found a way to build best dive watches with GMT function.
“True GMT” vs “Calling GMT Watches
Let us get to know some truth about GMT watches. If you go online, you will be surprised to see watch fans talk of “true GMT” and another “calling GMT”
These names comes from the type of movement that runs the GMT watch hands. For example, Rolex GMT master II came out in 1983 – 30 years after Airman was introduced. You could independently adjust the hour hand in a Rolex GMT Master II watch, without stopping the seconds hand or disturbing the other hands.
If your GMT hand indicated your home time while on a long journey, all you needed to set a new destination local time, was to pop your hour hand over to quickly. This was more faster and more convenient, if you wanted to set your GMT watch ready for travel. many considered these type of watches as the “true” GMT or “flyer” GMT – best for travel adventures.
In some modern GMT watches, the movement have independently adjustable GMT hands rather than independently adjustable hour hand. This is best and convenient for tracking multi-timezone while at home.
Such watches are referred to as “office” or “caller” GMT watches. They are better, if you have business partners across multiple timezones and you want to set office time or business hours.
Whether “true” or “office” GMT, they really work find just like any GMT watch will run when you are traveling.
