GMT Watches for Travelers at Work and Play

The second time zone can be displayed in a variety of ways, providing a wide range of choices for watch designers. A watch with a second time zone can be the center of attention and announce loudly that its owner is a globe-trotter. However, the attached display can also be carefully hidden, visible only when the wearer commands it to appear. Visually readable 12-hour dials are available as explicit 24-hour dials and various non-traditional displays. The target group plays an important role because the second time zone can provide valuable services to very different types of people.  
Pilots, who frequently land in different countries, use UTC (Universal Time Coordinated) exclusively for radio communications, flight plans and logbooks. A watch with a second time zone is very helpful to pilots. Not surprisingly, some replica watches have been developed specifically for this purpose, in the same style as traditional pilot watches.
The best famous representative of this genre is surely the Rolex GMT-Master, developed in 1955 in response to a list of requirements specified by Pan American World Airways. At that time, the distinctive rotatable bezel was the only option for setting the time in the second zone because the 12-hour and 24-hour hands could not be reset independently. The position of the 12-hour hand could be reset in one-hour increments only after 1982, when Rolex introduced a new movement. The time in a third zone could also be shown by rotating the bezel to correspond with the 24-hour hand, but this meant that the time in the second zone couldn’t be read until the bezel was returned to its original position.
Tudor, fake Rolex’s sister brand, started using the same color scheme on the Black Bay GMT in 2018 and floats along with the retro wave, while rolex replica  has been building its classic for more than half a century with only minor visual modifications.
Arguably the most eye-catching and original version is the one that Rolex offers with a distinctive blue-and-red 24-hour scale. This colorful model, which its fans have nicknamed “Pepsi,” shows the daytime hours from 6 am to 6 pm in red and the nighttime hours in blue. In the past, this color scheme was used to quickly distinguish between day and night time.
