The Tag Heuer Grand Carrera Calibre 36 RS Caliper Automatic Chronograph is the world's first mechanical chronograph which measures and displays time to 1/10th of a second. The unequalled Caliper Rotating Scale magnifies the 1/10th second scale for at-a-glance readings.
The C.O.S.C. certified movement oscillates at an astonishing 36,000 vibrations per hour. This enables the central seconds hand to count 1/10th of a second intervals.
Inspired by GT race car engine design, the breakthrough Tag Heuer Grand Carrera Rotating System replaces traditional hands with dashboard style discs: the readability is optimum while maintaining effortless elegance.
