The TAG Heuer Grand Carrera Calibre 36 RS Caliper Concept is quite an impressive concept. Featuring a world’s first, the Grand Carrera Calibre 36 RS is the only automatic chronograph capable of measuring and displaying 1/10ths of a second. A COSC-certified movement oscillates at an ultra high 36,000 vibrations per hour (vph), allowing the watch to measure 1/10th of a second intervals.

The Calibre 36 RS is housed in a 43 mm in diameter case which has a black titanium carbide coating. There are “black gold” accents all over the dial of the watch including the indexes, TAG Heuer logo and the hands. The two rotating systems indicating the chronograph minutes at 3 o’clock and the chronograph hours at 6 o’clock systems also use black gold. The watch also features a Linear seconds display a 9 o’clock.


Another innovative design element is the way the watch displays the information. TAG Heuer developed an exclusive Rotating scale that permits precise reading of 1/10th of a second.

This concept watch is so exclusive that the design is featured on the dashboard of the limited edition Ken Okuyama designed K.O.7 sportscar, that was on display at the TAG booth this year at Baselworld.

To add to the sporty automotive-inspired design of the watch, they added a caliper to the dial, which connects to the hour and minute counters at 3 and 6 o’clock. They even perforated the strap, to add to the sporty design.
The racing inspired “black gold” accented, ultra high precision 36,000 VPH COSC-certified 1/10th second chronograph, is by far one of the best looking TAG Heuer watches I’ve seen.
