TAG Heuer writes a new chapter with the TAG Heuer Monaco Split-Second Chronograph

TAG Heuer writes a new chapter in high-performance horology with the TAG Heuer Monaco Split-Seconds Chronograph Air 1, a high-tech timepiece that continues the Swiss watchmaker’s rich legacy of precision chronographs inspired by motorsport, and one of the most complex watches it has ever created.
Showcased at Dubai Watch Week 2025, this 30-pieces limited edition represents the Maison’s boldest expression of its avant-garde spirit.

A VISION SHAPED BY AIR
Inspired by the aerodynamic world of hypercars, the TAG Heuer Monaco Split-Seconds Chronograph Air 1 redefines what is possible in case design. Crafted from Grade-5 titanium using Selective Laser Melting (SLM), an additive manufacturing technique adapted from aerospace engineering, its sculpted form appears to have been carved by the wind itself. Weighing just 85 grams, the watch’s hollowed, architectural structure channels the lightness and flow of Formula 1® design. The intricate twin-layered honeycomb mesh recalls hypercar engine covers, while accents of 2N yellow goldand black DLC-coated titanium create a striking and contemporary aesthetic.
At its heart beats the Calibre TH81-00, TAG Heuer’s most complex chronograph movement to date. Developed in collaboration with Vaucher Manufacture Fleurier, this high-frequency automatic movement with a 65-hour power reserve delivers flawless precision and features the legendary rattrapante (split-seconds) function. Composed largely of lightweight titanium components, the TH81-00 combines strength and finesse, its checkered-flag finishing visible through the sapphire caseback as a mechanical celebration of TAG Heuer’s racing DNA.

THE LEGACY CONTINUES
For over 160 years, TAG Heuer has led the art of precision timekeeping, from the Heuer Mikrograph of 1916 to today’s most sophisticated chronographs. The TAG Heuer Monaco Split-Seconds Chronograph Air 1 now stands as a gem of this evolution, merging heritage with the future of watchmaking. Elegant, powerful, and visionary, it embodies the spirit of innovation that defines TAG Heuer.

“The TAG Heuer Monaco Split-Seconds Chronograph Air 1 is a watchmaking revolution,” said TAG Heuer chief executive Antoine Pin. “Think of it this way: thanks to SLM, a watch engineer has been able to deliver a watch designer's wildest creation. The SLM manufacturing process, adapted by the TAG Heuer LAB, takes us into a new dimension, rewriting the received laws of case design. And where better to do that than in the avant-garde Monaco, which in 1969 became the world's first water-resistant square-cased automatic chronograph. The TAG Heuer Monaco Split-Seconds Chronograph Air 1 marks a new dawn for a true design icon and marks the beginning of a new series of conceptual timepieces involving innovative technologies for the brand.”
