What Makes an Automatic GMT Watch the Perfect Travel Companion?

Have you ever landed overseas and suddenly lost track of the time back home? Perhaps your phone battery ran out, or your signal became confused due to jet lag. There is an easy mechanical solution to that problem.

An automatic GMT watch shows you two different time zones simultaneously without requiring batteries or mobile applications. In this article, you will learn about the complication mechanism, the importance of self-winding watches for business trips and jet lag, the ability to use a rotating bezel for showing the third time zone, and the reasons for choosing a durable construction.

All this makes this kind of watch perfect for your flights, meetings, and diving.

What Is A Dual Time Zone Watch and How It Works

A dual time complication is made up of the local time and another reference time that are displayed at the same time. Originating in the 1950s for use by pilots who had to know Greenwich Mean Time, now known as UTC time, and the local time for navigation purposes, this type of watch has had many practical uses.

In addition to the regular three hands found on a normal watch, there is an additional one on the GMT that makes a complete circle in 24 hours. The 24-hour hand works in conjunction with a 24-hour scale that can be found on the dial or bezel. In this way, it is easy to know what time it is morning or night at your point of reference without the AM or PM distinction.

The Fourth Hand and 24-Hour Scale Explained

The main hands show the local time. The GMT hand is slower than the other two hands, so it indicates the home time using the bezel. Dark colors indicate nighttime, while light colors indicate daytime for most of the bezels.

A third time can be indicated by rotating the bezel. Keeping the GMT hand fixed to the home time and keeping the main hands fixed to the local time, one can move the bezel either way by plus or minus hours.

Why An Automatic GMT Watch Simplifies Crossing Time Zones

It has a perpetual mechanism in this traveler’s watch whereby it will be fully charged through your activities like arm movements. All the movements of the current era have a 42-hour power reserve capability, which means that the watch will remain charged from Friday to Monday.

The watch does not require charging. You set it to your time zone once during its use. At the destination, you adjust the GMT hand using the quick-set crown by one hour. The GMT hand, minute hand, and seconds hand continue to move to maintain the accuracy of the watch.

True Traveler Versus Caller Functions for Real Travel

These top guides make a point of this difference. In a True or Traveler GMT watch, the 12-hour local hand advances on its own without stopping, while the 24-hour hand jumps, ensuring a continuous flow of the local time. This will be perfect for you if you regularly move through different time zones and want the second hand to continue moving.

In a caller or office GMT watch, you can change the position of the 24-hour hand, while the local time stays the same. This will suit your needs perfectly if you don't travel around much but have to coordinate your activities with people in other countries.

Durability Matters: And Why A GMT Dive Watch Wins For Adventure

Traveling can be tough, and so can a GMT that can be worn. A dive-ready GMT will come with 600 meters or 2000 feet of water resistance, thick sapphire glass, and a unidirectional sapphire bezel featuring 120 clicks along with Super-LumiNova markings for toughness, scratch resistance, and low-light conditions.

Home time can be read through the GMT hand, local time through the main hands, and the bezel can be used to dive and read a third time zone. No batteries are required, as this watch will ensure reliability through all kinds of journeys. The GMT dive watch will have the home time being tracked even while diving in a foreign land, making it easy to combine the dive timing and the travel functionality, and a second time zone reading can be done through a 24-hour hand.

Such craftsmen, who specialize in creating watches for this particular segment of watch lovers, include Ocean Crawler with its American-assembled Core Diver GMT featuring a Sellita SW330-2 and full sapphire bezel.

Choosing the Right Travel Timepiece

Your perfect travel watch needs no thought at all. Not only does it indicate home and local times simultaneously, but it is also self-winding and sturdy enough to resist any harsh conditions, from the busy airport to the salty ocean waters. 

Pick up a dual-time zone watch featuring a 24-hour indicator, separate hour hand, and jumping hours to get accurate readings fast. Should your trips include water and rough terrain, a GMT diving watch with sapphire glass, water resistance to 600 meters, and a 42-hour power reserve would give you extra confidence from the moment you take off until the landing. Well thought out and proven by materials used and a five-year Ocean Crawler guarantee, one complication will do the job of two watches.
