Pilots, who frequently land in different countries, use UTC (Universal Time Coordinated) exclusively for radio communications, flight plans and logbooks. A luxury fake watch with a second time zone is tremendously helpful for aviators. And it’s not surprising that some watches were developed especially for this purpose and are styled like traditional pilots’ watches.
The best-known representative of this genre is surely the black dial copy Rolex GMT-Master II, 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 high quality copy 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.
Arguably the most eye-catching and original version is the one that Rolex copy with blue and red bezel 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 differentiate daytime and nighttime hours.
