With its latest novelties unveiled at Geneva Watch Days, TAG Heuer is sending a clear message – it is pushing the limits of what is possible in design, engineering and storytelling. This is highlighted by way of two new showcases at the brand – a path-breaking new carbon hairspring that has been installed in two new watches, the TAG Heuer Monaco Flyback Chronograph TH-Carbonspring and TAG Heuer Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring, and a new moonphase watch (in three iterations) called the TAG Heuer Carrera Astronomer.
The TH-Carbonspring is a pathbreaking hairspring oscillator developed entirely in-house over the course of a decade, by the TAG Heuer LAB. The TH-Carbonspring oscillator improves the environmental resistance, shock absorption, and long-term stability of mechanical movements. The oscillator is resistant to magnetism, less affected by shocks, and benefits from the lightweight properties of carbon, increasing chronometric performance. Both the new models introduced use forged carbon cases and dials, with a spiral motif echoing the hairspring’s shape. The Monaco Flyback Chronograph houses the in-house TH20-60 Calibre, an automatic chronometer-certified movement with an 80-hour power reserve. The Carrera Chronograph Tourbillon Extreme Sport features the TH20-61 Calibre, an automatic chronometer-certified chronograph tourbillon with a 65-hour power reserve. Each watch is limited to 50 pieces.
The Monaco, which will be available in December 2025, features a 39mm black forged carbon case, in the collection's signature square shape, a black carbon dial with spiral-shaped engraving, and a black rubber strap with textile embossing. The hour and minute hands and markers feature white Super-LumiNova for night-time readability. The sapphire crystal case back brings the mo tor, which offers a flyback function, to life. The watch is priced at CHF 17,000.
The Carrera’s 44mm forged carbon case houses a black carbon dial with spiral engraving and a flying tourbillon at 6 o’clock. A black rubber strap and forged carbon bezel with tachymeter complete the design. Like the Monaco, the watch is water resistant to 100 meters and equipped with a sapphire crystal that displays its intriguing inner workings, such as the mainplate with a checkered pattern and the skeletonized rotor. The Carrera Chronograph Tourbillon Extreme Sport TH-Carbonspring will be available in the first quarter of 2026, with a retail price of CHF 40,000.
The Carrera Astronomer introduces a contemporary approach to the moonphase, a complication rarely seen in the brand's modern-day collection. Unlike traditional, often symbolic moonphase indications, TAG Heuer’s approach favors accuracy and legibility, offering a clear visualization of the moon’s position across its 29.5-day orbit. Each day at 1:00 AM, the lunar disc makes its precise advancement, mirroring the real-world movement of the moon.
The watch also resonates with TAG Heuer’s long-standing connection to space. In 1962, astronaut John Glenn wore a specially modified Heuer 2915A stopwatch aboard NASA’s Friendship 7 spacecraft, relying on it as he orbited Earth three times.
TAG Heuer presents three variations of the Astronomer, all in stainless steel. The first pairs a silver sunray dial with black and gray accents. A limited-edition model of 500 pieces features turquoise Super-LumiNova highlights on the dial and hands and is complemented by a gray leather strap. A second 500-piece limited edition adds rose gold tones to the case, hands, and flange, paired with a two-tone bracelet. Each watch measures 39mm in diameter and is water resistant to 100 meters.
The casebacks display an astronomical observatory motif with a Victory Wreath engraving. Behind them ticks TAG Heuer's self-winding Calibre 7 with a power reserve of up to 56 hours. The watch is priced starting at CHF4,350.
