TAG Heuer TH81-01

The TAG Heuer TH81-01 is an automatic split-seconds chronograph movement developed in collaboration with Vaucher Manufacture Fleurier. Operating at 36,000 vph (5 Hz), it features a column-wheel-controlled chronograph with a split-seconds mechanism actuated via a pusher at 9 o'clock. The movement provides a power reserve of approximately 65 hours with the chronograph disengaged, reduced to 55 hours when timing functions are in use. Constructed from grade-5 titanium with over 350 components, it is fully skeletonised and hand-finished. The TH81-01 is integrated into the TAG Heuer Carrera collection.
