The term "MT" stands for "Greenwich Mean Time" (Greenwich Time). The abbreviation GMT is derived from the name of the Royal Observatory in London's Greenwich Park. When Greenwich is referred to as the prime meridian (the zero meridian) of the Earth, it takes on a unique significance.
Quartz or analog timepieces are the most common types of GMTs. GMT watches contain a GMT hand in addition to the hour, minute, and second hands like traditional analog watches, which shows 24 separate time zones corresponding to 24 cities.
Due to the fact that GMT watches make it simple for users to keep track of time in various time zones. For people who regularly switch between time zones, this watch is a good choice.
