"GMT" stands for Greenwich Mean Time and is the "0" point on the 24 hour scale of international timezones. GMT watches were developed mostly for aviation purposes and include both the "local" and "GMT" time. Most GMT watches have two hands to display the time in a 12-hour format and an independently adjustable 24-hour hand. If the 24-hour hand is not independently adjustable, it merely serves to indicate whether the time is AM or PM. GMT watches are typically used to know the time in any two time zones. In addition, many GMT watches have a rotating 24 hour bezel. All in all, GMT watches are used to show two timezones at once, with traditionalists setting the GMT hand to the actual GMT time.
