TAG Heuer Tackles Avant-Garde Horizons

In Geneva this September, TAG Heuer revealed a pair of landmark innovations that will shape the future of fine watchmaking.

The maison introduced the TH Carbonspring oscillator, a decade in the making, alongside the Carrera Astronomer, a poetic yet scientifically precise interpretation of the moon phase.

Together, they embody TAG Heuer’s forward-looking spirit, its relentless engineering culture, and its commitment to horology as both art and performance.

The TH Carbonspring: A New Beating Heart

For over three centuries, the oscillator has defined mechanical watchmaking, yet until now it has remained vulnerable to magnetism, shocks, and the limitations of traditional materials.

TAG Heuer’s newly patented TH Carbonspring changes that. Conceived and produced entirely in-house at the TAG Heuer LAB, it took nine years of research, thousands of tests, and four patent filings to achieve.

This carbon hairspring delivers three decisive advantages: it is amagnetic, resistant to shocks, and significantly lighter, thereby improving chronometric stability. It is backed with a five-year warranty and marks the most important advance in regulating organs since the arrival of silicon.

To debut this breakthrough, TAG Heuer has re-imagined two icons. The Monaco Flyback Chronograph TH Carbonspring (39 mm, CHF 17,000, available December 2025) is a stealth piece in forged carbon, with luminous black-gold hands and an in-house TH20-60 calibre offering an 80-hour reserve.

The Carrera Chronograph Tourbillon Extreme Sport TH Carbonspring (44 mm, CHF 40,000, available Q1 2026) adds a forged carbon tachymeter bezel and the TH20-61 tourbillon calibre with 65 hours of autonomy.

Both are COSC-certified, water resistant to 100 metres, limited to 50 pieces, and presented in bespoke packaging.

These are not merely limited editions; they are foundation stones for a new generation of high-performance watches, built on an innovation that redefines the oscillator itself.

The Carrera Astronomer: Lunar Precision

If the Carbonspring is about mechanical resilience, the Carrera Astronomer is about celestial truth. At six o’clock, a rotating disc displays seven illustrated lunar stages, advancing each day at 1.00 a.m. to remain in perfect synchrony with the 29.5-day cycle.

It is powered by the new Calibre 7 with a 50-hour reserve and housed in a 39 mm case, water resistant to 100 metres.

Three models form this lunar trilogy:

• Carrera Astronomer WBX2110.BA0044 – stainless steel with silver dial, bracelet, and black moonphase disc. CHF 4,550. October 2025.
• Carrera Astronomer WBX2112.FC6615 – silver dial with turquoise highlights, grey leather strap, limited to 500 pieces. CHF 4,350. October 2025.

Carrera Astronomer WBX2111.BD0002 – two-tone steel and 18K 5N rose gold, fine-brushed bracelet, limited to 500 pieces. CHF 6,900. October 2025.

All three feature casebacks engraved with a space observatory and Victory Wreath, underscoring the collection’s link to TAG Heuer’s pioneering role in space exploration since John Glenn’s 1962 Friendship 7 mission.

A Statement of Victory

TAG Heuer’s presentation in Geneva was not about nostalgia but about intent. The TH Carbonspring has redefined the regulating organ of mechanical watches. The Carrera Astronomer has given the moonphase complication a new language of clarity and precision.

This dual unveiling reinforces the maison’s credo of being Designed to Win. It is a story of scientific rigour, creative vision, and the sheer resilience to pursue a single idea for almost a decade.

These watches are instruments of precision that embody the rhythm of both human innovation and the cosmos itself.
