The abbreviation GMT (Greenwich Mean Time) is used in the watch-making industry to
indicate those modules with more than one time zone: i.e. they are particularly useful for
frequent world travelers. The reference to Greenwich, which is one of the London
boroughs, is due to the fact that it is the location of Greenwich observatory which has
been the reference point for the measurement of longitude since 1884. The Greenwich
Meridian, which divides the globe into two parts, has been adopted internationally as the
zero of longitude.
