TAG Heuer Calibre 360

Calibre 360 is an automatic chronograph movement developed and manufactured by TAG Heuer. Operating at an ultra-high frequency of 360,000 vph (50 Hz), it features a dual-escapement concept with two parallel escapements designed to improve amplitude stability during timing functions. Introduced in 2005, the movement appeared in select TAG Heuer Monaco and Carrera models before being discontinued.
