TAG Heuer's Innovative Carbon Hairspring, Crafted Over 9 Years, Now Prepared for Large-Scale Manufacturing
TAG Heuer, a pioneer in watchmaking, has made a groundbreaking announcement with the release of two new models featuring the innovative TH-Carbonspring. The Monaco Flyback Chronograph TH-Carbonspring and the Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring are set to change the landscape of watchmaking, addressing the limitations of traditional silicon hairsprings.
A Leap in Watchmaking Technology
The TH-Carbonspring, produced using a Chemical Vapor Deposition (CVD) process with carbon nanotubes cultivated at temperatures between 600-850°C, offers superior shock absorption compared to silicon hairsprings. It has been tested to remain intact under extreme shock loads of 5,000g, a significant improvement over its silicon counterparts.
TAG Heuer has bypassed patent-protected silicon technology to achieve independence in production, addressing the supply chain limitations and licensing costs associated with silicon. The company has developed four proprietary patents for the CVD growth process, collet integration method, and other aspects of the TH-Carbonspring production.
The Monaco Flyback Chronograph TH-Carbonspring
The Monaco model, iconic in its design, is the first to feature the TH-Carbonspring. It boasts a 39mm forged carbon case, pushers, and crown, paired with a matching rubber strap with a DLC titanium clasp. The dial of the Monaco Flyback Chronograph TH-Carbonspring features spiral engravings that mirror the geometry of the TH-Carbonspring.
This model houses an in-house TH20-60 automatic flyback chronograph movement, offering a power reserve of 80 hours. It delivers flyback functionality with an 80-hour power reserve, making it a standout choice for those seeking precision and durability. The Monaco Flyback Chronograph TH-Carbonspring will be available starting December 2025, priced at $17,900, and is limited to 50 pieces.
The Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring
For those seeking a larger watch face, the Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring offers a scaled-up 44mm case. It retains the 100m water resistance and COSC chronometer certification, ensuring durability and precision. The watch features a tachymeter bezel and comes with a matching rubber strap with a DLC titanium clasp.
The Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring houses an in-house TH20-61 automatic chronograph tourbillon movement, offering a power reserve of 65 hours. This model adds a flying tourbillon complication to the Carrera line, making it a unique and attractive choice for watch enthusiasts. The Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring will be available in Q1 2026, priced at $42,100, and is also limited to 50 pieces.
Both watches retain the black-gold hands with white Super-LumiNova, ensuring easy readability in low light conditions. The forged carbon cases, pushers, and crowns of both models contribute to their sleek and modern aesthetic.
TAG Heuer's industrialization of the carbon hairspring, the TH-Carbonspring, marks a significant breakthrough in watchmaking. With its superior shock absorption and resistance to traditional assembly errors, the TH-Carbonspring could potentially change watchmaking as we know it.
