TAG Heuer: TAG Heuer Carrera Calibre 360/2006
At Baselworld 2005 TAG Heuer presented the most accurate mechanical timepiece ever crafted, the "Calibre 360" Concept Chronograph. This timepiece is the first mechanical wrist chronograph to measure and display time to 1/100th of a second, thanks to the exceptionally high frequency of its balance wheel, which oscillates at 360,000 beats per hour, 10 times faster than any other chronograph.
To ensure precision adjustment and independent operation, the basis of the "Calibre 360" is an automatic movement, the TAG Heuer Calibre 7, with a 42-hour power-reserve and a heart beating at 28,800 vibrations per hour. This movement has been certified as a chronometer by COSC (Swiss Official Chronometer Control institute).
