SAVOIR FAIRE TAG Heuer Carrera: The Future of Time, Forged in Carbon

In 1675, Christiaan Huygens changed watchmaking forever with the invention of the hairspring — the delicate, spiral-shaped spring regulating the oscillations of a mechanical movement. Three and a half centuries later, TAG Heuer introduces the TH-Carbonspring, a carbon-composite hairspring engineered after nine years of research and development, marking a new era in horological technology. Extremely light, shock-resistant, and amagnetic, this innovation pushes the boundaries of chronometric performance.

Patented by TAG Heuer and produced exclusively in-house, it marks a significant step toward perfect isochronism, delivering stable, accurate timekeeping across changing conditions.

This regulating innovation finds its ultimate expression in the TAG Heuer Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring, revealed at Geneva Watch Days 2025. Built for intensity, the timepiece is built in forged carbon, from its 44mm case to its bezel, crown and pushers. Every component has been optimized for strength and lightness.

At the heart of the watch beats the Calibre TH20-61, a COSC-certified movement fitted with the TH-Carbonspring oscillator and a flying tourbillon at 6 o’clock. The dial’s spiral-engraved pattern echoes the hairspring’s geometry, framed by minimalist subdials, facetted black gold hands, and white Super-LumiNova® for legibility in any environment. Engineered for ultimate precision, this is a timepiece born for endurance.

Limited to just 50 pieces worldwide, the TAG Heuer Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring is presented in a dedicated black display box. As both an homage to horological heritage and a leap into the future of chronometry, it exemplifies the Maison’s avant-garde DNA: where high-complication craftsmanship meets sport-tested innovation — where every fraction of a second counts.
