TAG Heuer Link Calibre 36. The TAG Link Calibre 36 is you typical chronograph watch, but it has a automatic movement which runs a at amazing 36,000 vph. This is what TAG Heuer calls its Calibre 36. This allows it to measure accuracy to within 1/10th of a second. While this was a great feat, the clocks typical chronograph dial and bezel would make it hard for the user to take advantage over it 1/10th of a second accuracy versus a chronograph accurate to within 1/8th of the second. The problem is the display. Trying to figure out if 40.6, 40.7 or 40.8 seconds could be pretty difficult.
