Watchmakers are not what they used to be, as they are now turning into mathematicians, physicists, chemists. In their quest for precision, they are shaking up traditional watchmaking know-how through their cutting-edge expertise in materials. With the Carrera Heuer Calibre 02T Tourbillon Nanograph, TAG Heuer is addressing the future of watchmaking through the unprecedented use of carbon at the very heart of its movement. A world first in watchmaking, a patented carbon composite balance spring now equips the Heuer 02T chronograph movement, which is chronometer-certified and equipped with a tourbillon regulator. It offers numerous advantages, since this ultralight and low-density hairspring is insensitive to gravity and shocks. Its perfectly concentric oscillations increase the precision of the watch. Totally non-magnetic, it also ensures optimal thermal behavior. To welcome this distillation of innovation, the Carrera attires its sporty lines in titanium and carbon. Echoing the nanoscopic hexagonal structure of the composite used in the manufacture of the balance-spring, the openwork dial features multiple identical patterns. Technology and performance, from start to finish.
