Following the successful introduction of the Grand Carrera, TAG Heuer then announced a special Grade-two titanium version of the watch at Basel 2008- The Grand Carrera Calibre 36 Concept Chronograph. The concept watch took the design of the Grand Carrera series further- a much more “industrial” design with an emphasis on extreme sportiness rather than elegance.
Like the rest of the range, the Grand Carrera Calibre 36 RS uses the Rotating Disc system in place of traditional sub-dials. The disc at 3 0’Clock shows elapsed minutes, while the counter at 6 o’clock shows elapsed hours. On the left hand-side of the dial is a narrow window that shows seconds using TAG Heuer’s Linear System (“LS”)- again a rotating disc that rotates every 20 seconds. From 0-40 seconds the disc shows a black line, while from 41-60 the line changes to red.
What distinguishes the Grand Carrera Calibre 36 from other watches in the Grand Carrera range is the Caliper system, an ingeniously simple way of allowing the chronograph to display 1/10th second accuracy. The Calibre 36 movement has always been able to achieve 1/10th second precision, but the challenge has always been how to show this fraction of time on the dial.
The highlight of the dial was the metal bridge connecting the two sub-dials with its Cotes de Geneve finish. From a technical perspective, the key development was the Caliper system.
The most special of all Carrera models, very sporty, very avant-garde, built in a fantastic black PVD titanium case with 43mm, very light.
This particular example is in mint condition with full set of boxes and all papers.
