160_EN / 12.16
This reference time was used for much of the 20th Century, before being replaced by the more precise Coordinated Universal Time (UTC) in 1972.
Though regularly used as a synonym for UTC+0 due to its similarity, GMT is a different term since it is measured by the Earth's rotation whereas UTC uses
atomic clock technology.
In the world of watchmaking, the acronym GMT is used when the watch dial possesses a second time zone display; you can select the one you want.
