The GMT offers an original method of visualizing world time by means of a rotating three-dimensional globe in conjunction with a second time zone indication. An inclined Tourbillon 24 Secondes escapement regulates the timing of the movement.
The globe simultaneously permits the visualization of the time as well as the position of day and night across different continents via the 24-hour ring around the equator.
