For the first time ever, TAG Heuer scientists have developed a carbon composite hairspring. Assembled atom by atom, from elemental carbon, it governs the oscillations of the balance wheel. This advanced component exhibits outstanding shock-resistance, is anti-magnetic, and offers optimum temperature performance.

As the true heart of a mechanical watch, the carbon composite hairspring demonstrates unique know-how. Created and assembled exclusively at TAG Heuer, its supreme quality ensures optimum precision.

The carbon composite hairspring is paired with an aluminum balance wheel including white gold inserts. The elegant geometry and perfectly concentric oscillations are rooted in improved performance and give a unique signature to the watch’s heartbeat.

An unprecedented innovation

In addition to being the first watch to be regulated by this carbon composite hairspring, the TAG Heuer Carrera Calibre Heuer 02T Tourbillon also presents two other complications, which are some of the most prestigious in traditional watchmaking: a tourbillon capable of almost hypnotic movements, which cancels out differences in rate, and a COSC-certified chronograph, which meets the official standards for chronometers.

A groundbreaking design

The nanoscopic (million time smaller than a millimetre) hexagonal pattern of the hairspring’s carbon composite material is mirrored in the design of the Carrera HEUER 02T Tourbillon Nanograph, the newest member of the brand’s iconic collection since 1963.

The multi-layered dial presents sand-blasted and finely brushed hexagons on the movement plate, which can be seen through the openworked dial. The motif can also be found on the black PVD-treated oscillating weight, revealed through a sapphire case back.

Once again, TAG Heuer demonstrates its avant-garde spirit by pushing the limits, drawing ever closer to perfect precision in mechanical watchmaking.
