GMT and Worldtime Functions
To fulfill the dream of travelers.
In watchmaking, the GMT movement provides a vital function to modernday travelers: timing two locations on one wrist. With a 24-hour second time zone that is easily changed depending on the wearer’s location, BALL GMT watches are unique. To further enhance the readability, the second time zone display has incorporated our Swiss micro gas light tubes. Most of our GMT collections feature the world’s only selfilluminated second time zone, not only the hour hand, but also the hour itself is traced across the dial.
Be aware of the time everywhere in the world
To provide watches that can operate at the same time in all corners of the globe, BALL Watch Company introduced the world’s first mechanical movement including a day and date function combined with a 24-hour time zone display. Developed specially in the BALL workshops and grafted onto a standard caliber, an additional worldtime module drives a disk engraved with the names of the world’s main metropolises rotating automatically in the reverse direction to the hands to simultaneously indicate the time in 24 different geographic zones.
