Εαν δεν κανω λαθος, τα GMT ειναι οσα εχουν ξεχωριστό, ομοαξονικό pointer για δευτερη ωρα.

Dual TimeIn dual time watches, both displays are powered by the same movement.
GMT (Greenwich Mean Time)The watch displays two or more time zones.
GMT with Independent Hour HandThis variety of GMT is a further development of the original. What makes it different is that the regular hour hand is set independently of the 24 hour hand, which completely changes the functionality of the watch.
GMT with Fixed Hour HandIntroduced by Rolex in the 1950's, this GMT complication is considered a pilot's watch. Its unique additional hour hand makes one revolution around the dial per day; pointing to twelve indicates midnight and pointing to six indicates noon.
