TAG Heuer TH20-02

The TAG Heuer Calibre TH20-02 is an automatic chronograph GMT movement manufactured by TAG Heuer. Based on the TH20 family architecture, it combines a column wheel and vertical clutch for chronograph engagement with an independently adjustable 24-hour hand for a second time zone. The movement beats at 28,800 vph (4 Hz) and delivers approximately 80 hours of power reserve from a single barrel with bidirectional winding. Functions include hours, minutes, seconds, date, chronograph, and GMT, with finishing visible through a sapphire case back. The movement is in production.
