A NEW SPIRAL FOR A MAJOR INNOVATION
Always at the avant-garde, TAG Heuer unveils in 2019 a new type of hairspring, built with carbon composite. Previously made of metal, Elinvar or Silicium, the hairspring is a small spring attached to the balance wheel to form the regulating organ of the watch. Therefore, it also guarantees its precision. Patented by TAG Heuer, the hairspring is an extremely difficult element to produce and assemble. However, it nearly adapts to all movements and regulating organs with the same efficiency. Requiring the manual intervention of 4 watchmakers, the ISOGRAPH technology has been integrated into the Heuer 02 Tourbillon house movement, combining two extraordinary elements. TAG Heuer thus confirms the full extent of its savoir-faire.
UNMATCHED CHRONOMETRIC PRECISION
Key element in the operation and precision of a watch, the hairspring is also essential in terms of time measure. An area in which the ISOGRAPH technology offers very high performances, thanks to a custom-made balance wheel and a carbon composite hairspring more resistant than ever. Models featuring the ISOGRAPH technology are all certified chronometer by the COSC.
CARBON: THE IDEAL MATERIAL
Chosen by the TAG Heuer institute to manufacture its new hairspring, carbon has replaced metal, Elinvar and Silicium. Lightweight, shock resistance, stability, anti-magnetism, optimal thermal behavior: its numerous advantages provide unique performance and improved accuracy.
