The second generation of GMT watches provided a GMT hand independent of the hour hand, which made it much easier to set a watch with a GMT Feature. This allowed more flexibility and more convenient operation, making this type of GMT watch the most popular model for frequent fliers to this day. However, this development brought a few minor technical differences.

By 1955, the atomic clock had been invented, and in 1960 the US and UK synched their atomic radio time signals into what would become Universal Time Coordinated, or UTC, which effectively replaced that meridian line that passes through the Royal Observatory in Greenwich.
The GMT watch is brilliant, not because of its complexity but because of its simple ingenuity. Because the movement's going train (primary series of gears) in a conventional watch is made to spin the hour hand around the dial every 12 hours, all that is required to become a GMT tracker is simply a second hour hand geared to run half as fast and an additional 24-hour time scale. In other words, the 24-hour hand circles the dial once a day instead of twice, its tip pointing to the corresponding hour, leaving no confusion as to whether it’s a.m. or p.m.
