After almost a decade of research, TAG Heuer launches the innovative TH-Carbonspring, made of carbon, and used on two new limited edition models with forged carbon cases.
TAG Heuer presents the TH-Carbonspring, a technology that redefines the standards of mechanical precision and ushers in a new era for the company. After almost a decade of research, the TAG Heuer LAB has therefore developed the innovative TH-Carbonspring completely in-house, made of carbon, which represents a major technological innovation in the watch industry. This innovation is launched in the 350th anniversary year of the invention of the modern balance spring by Christian Huygens, opening a new chapter in the history of mechanical watchmaking.
The TH-Carbonspring is not simply an evolution of existing technologies, but a true revolution, which overcomes the limitations of traditional steel and silicon spirals, offering superior performance in terms of environmental resistance and long-term stability.
The TH-Carbonspring is completely non-magnetic, a key feature in the digital age where we are surrounded by electronic devices that emit magnetic fields. This property ensures that the watch maintains its accuracy even in the presence of strong magnetic interference. In addition, ghanks to the properties of carbon, TH-Carbonspring offers superior impact resistance, protecting the movement from stresses that could compromise chronometric accuracy, even during the most common daily activities. To this must be added that the properties of carbon lightness reduce the inertia of the spiral, leading to superior chronometric performance and greater stability of the movement over time.
Monaco and Carrera: the first watches with TH-Carbonspring technology
The first two models to boast the use of the new TH-Carbonspring are the Monaco Flyback Chronograph and the Carrera Chronograph Tourbillon Extreme Sport, both in limited editions of 50 pieces.
TAG Heuer has chosen its two most iconic models for the debut of this revolutionary technology. One is the Monaco Flyback Chronograph TH-Carbonspring, available from December, equipped with TH20-60 calibre (mechanical automatic, 28,800 vibrations per hour, 80-hour power reserve), chronometer-certified by the Cosc and limited to only 50 numbered pieces. It has a 39 mm forged carbon fibre case with a black dial (also in carbon) featuring an original spiral engraving.
The TAG Heuer Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring, available from the first quarter of 2026, is equipped with the automatic calibre TH20-61 (28,800 vib/h, 65-hour power reserve, Cosc chronometer) with chronograph and flying tourbillon. Also limited to 50 numbered pieces, it is equipped with a 44 mm carbon fibre case (as is the dial, also engraved with a spiral). On the bezel, also made of carbon, is the tachymeter scale. Both models are water-resistant to a pressure of 10 atmospheres, have a sapphire crystal window on the back side and are combined with a black rubber strap with grade 2 titanium folding clasp.
The TH-Carbonspring: four patents
Both Emmanuel Dupas, TAG Heuer's Technical Director, and Antonie Pin, CEO of the company, stressed the importance of this innovation.
The development of the TH-Carbonspring represents one of the most prestigious achievements of TAG Heuer LAB, the Swiss manufacturer's innovation centre formerly known as the TAG Heuer Institute. The technology was developed and is fully produced, leveraging TAG Heuer's multidisciplinary expertise and vertically integrated network of Swiss production centres. The company has filed four patents related to this technology, with one already granted and three in the approval process, testifying to its originality and importance.
"Given the scope and complexity of the goal we set ourselves at TAG Heuer LAB, the innovation process involved countless steps and at least as many failures as successes," said TAG Heuer Technical Director Emmanuel Dupas. "You start with intuition, then formulate a hypothesis, move on to development and finally testing. Each result has its own weight. Sometimes a result reinforces confidence in one's hypothesis. Other times, however, it contradicts it and the hypothesis fails. There are no shortcuts. Only hard work, supported by a healthy scientific scepticism and the skills of one's team'.
Dupas also reflected on the achievement: 'We have dedicated nine years of our lives to opening a new chapter in the wonderful history of precision mechanical watchmaking, said. "We are immensely proud of this achievement and the role it will play in the history of this pioneering and innovation-focused company, as well as the everyday performance improvements it will offer TAG Heuer watch owners."
"The TH-Carbonspring is a major breakthrough in watchmaking and a milestone in the history of this infinitely innovative company with a 165-year history," added Antoine Pin, CEO of TAG Heuer. "But it is also a story of great mental strength and resilience. Imagine dedicating a decade to the realisation of a single idea. It is incredible. An epic and heroic achievement that only a brand designed to win could have achieved. And this is just the beginning. There are many complementary technologies in the pipeline and, in time, these will spread into our collections of high-performance, highly accurate mechanical watches. This is avant-garde watchmaking for the 21st century. This is TAG Heuer'.
