TAG Heuer TH80-00

The TAG Heuer Calibre TH80-00 is an automatic chronograph movement operating at 36,000 vibrations per hour (5Hz) with a 70-hour power reserve and 47 jewels. COSC-certified, it features TAG Heuer's TH-Carbonspring oscillator for magnetic resistance and chronometric stability. Its defining characteristic is a compliant chronograph mechanism using flexible bistable components instead of traditional levers and springs. The movement employs inverted construction, placing the barrel, gear train, balance, and escapement on the dial side.
