Tag Heuer launched their Calibre 360 chronograph wristwatch at Basel in 2005 with much fanfare, becoming the first mechanical movement capable of 1/100th seconds accuracy and display. Constructed with two trains, the tandem winding chronograph oscillated at 360,000 beats per hour and could be engaged without interfering with the watch movement. The manually wound chronograph featured a 100-minute power reserve aperture on the dial, with the going train was wound through the crown or rotor. The crown was moved in clockwise direction to wind the chronograph and in an anti-clockwise direction to wind the watch movement.

Following introduction of the watch in 2005, Tag Heuer released the rare Vanquish Calibre 360 Chronograph 1/100th. Produced in limited number of 12 timepieces the watch featured Grade 5 titanium (Ti5), developed in association with McLaren, a metal that can be polished. The Vanquish would lead to the later development of the Grand Carrera and Mikrograph timepieces.

The present Grade 5 titanium prototype was sold at international auction in 2005 with the proceeds benefiting the Geneva Musée de l'horlogerie.
