GMT is an abbreviation for Greenwich Mean Time, and it is positioned as "0" on the 24-hour international timezone scale. Simply put, a GMT watch is a timepiece that shows both a 24-hour and a 12-hour time scale. Check out our collection of luxury Fileteado GMT watches at Franck Dubarry to see what they look like. A GMT watch has become a timeless and fashionable device in recent years, but few people are aware of its fascinating history. A GMT watch is a timepiece that has a second-time zone. The wearer can set and view the time in another time zone in addition to the local time. GMT stands for Greenwich Mean Time, which was once considered the official world time. A SHORT HISTORY THERE WAS LATITUDE IN THE BEGINNING. It all began with the age of ship exploration. Humans began to travel long distances overseas, and it became necessary to map their progress. Remember when you were in geography class and we used to draw horizontal lines all over the world? These are known as latitude lines, and they are distributed around the Earth with the equator as the origin. The angle of the stars to the horizon was calculated by ship crews using a sextant: a device that calculated the angle of the stars to the horizon. However, knowing only the latitude was insufficient for plotting ships on a map. Vertical lines (longitude) were also required, which is where GMT enters the picture. AFTER THAT, THERE WAS GMT. Without a clear origin, it was eventually decided that the 0-degree vertical line should pass through Greenwich, London's Royal Observatory. The Prime Meridian was named after this line, and noon is declared when the sun reaches its highest point directly above it. However, due to the Earth's elliptical orbit and tilted axis, the true 12pm GMT is usually a few minutes out of sync each day. Fortunately, an annual average was calculated to reconcile this discrepancy, making GMT the average solar time that is unaffected by Daylight Savings Time. With the advent of GMT timepieces, it was possible to calculate longitude by observing the position of the sun at noon and calculating the difference between local and GMT time. So GMT watches are ideal for boat travel…but how does this apply to you? THE AGE OF AIR TRAVEL Then there's air travel. Humans were suddenly zooming across multiple timezones at breakneck speed. Pan Am Airlines approached Rolex and requested a new watch design to help their staff keep track of time. The GMT watch was invented in 1954. In short, the GMT watch was designed to show the GMT as well as another timezone. However, the watch's clever design allowed its owners to use it for other purposes as well. As a result, GMT watches quickly gained popularity, and soon after their initial release, people other than pilots were wearing them. THE PRESENT-DAY For businesspeople communicating with foreign clients, medical professionals attending conferences abroad, international travellers, and even those who prefer to stay in one timezone. GMT watches are suitable for everyone. However, since the early days of longitude, some things have changed, and we now use Coordinated Universal Time (UTC). It was invented in 1955 to replace GMT and is far more accurate than other time-keeping methods. To avoid major confusion and disruption to timezones, no significant changes were made to the GMT scale, and thus the term GMT is still widely used. HOW TO DISPLAY THE GMT AND LOCAL TIME The GMT watch's original function was to display GMT time, which is easily accomplished by aligning the 24-hour hands with that. As long as you know the timezone of your current location, you can change the position of the 12-hour hands based on the position of the 24-hour hands. If you are in Germany, for example, the timezone is GMT +1. If the GMT time is 9 a.m., simply set the 12-hour clock's hour hand to 10 and the minute hand to 0. HOW TO TELL THE DIFFERENCE BETWEEN AM AND PM Because some people aren't concerned with what time it is in Greenwich, the 24-hour clock can also be set to your current timezone. This way, you'll always be able to tell whether it's morning or afternoon, which is a feature that the traditional analogue watch lacks. HOW TO SHOW MULTIPLE TIME ZONES Some GMT watches have a rotating bezel, which is a ring feature around the watch's clock face. This frequently has markings to show different city timezones, so you can tell the time in multiple locations simply by turning the bezel. WHY DO PEOPLE WEAR GMT WATCHES? People now use GMT hands to indicate the time in another time zone or to sync it up to their local time to have an AM/PM indicator. The Rolex GMT-Master from the mid-1950s is one of the most popular GMT watches of all time. Rolex made it with a distinctive blue and red bezel for Pan Am airlines' pilots. Because of the bezel colours, most people refer to the watch as a "Pepsi bezel" Rolex, and the connection with Pan Am faded quickly. Other complications can be added to GMT watches. Breitling's in-house Chronomat GMT features a GMT hand as well as a chronograph for added functionality. While GMT watches were originally designed for pilots, they are now widely used by anyone who wants to track the time in two different locations. GMT watches also make excellent travel pieces for those who can't remember what time it is at home."
