TAG Heuer Monaco Split-Seconds Chronograph Air 1 in 3D-printed titanium, limited to 30 pieces

TAG Heuer has once again raised the stakes in high watchmaking with the Monaco Split-Seconds Chronograph Air 1—a hypercar-inspired, future-facing chronograph. The run is limited to just 30 pieces, and the price is 150,000 Swiss francs, roughly $124,000—firmly in supercar territory.

The case is made from Grade 5 titanium using Selective Laser Melting, essentially an advanced form of 3D printing borrowed from aerospace. This approach lets the structure be sculpted from the inside out, driving weight down to just 86 grams despite a 41 mm footprint and a notably thick 15.2 mm profile. On the wrist, that promises presence without the heft.

Inside beats the TH81-00 calibre: 36,000 vph, a 65-hour power reserve, or 55 hours with the chronograph running continuously. Through the caseback you can see a complex exoskeleton and honeycomb patterns that recall hypercar engine covers. The dial layers sapphire elements, black sapphire plates, and highlights in yellow gold, underscoring the performance-first aesthetic.

Water resistance is 30 meters—more splash protection than swim-ready—so the pool isn’t its natural environment.

TAG Heuer describes the Air 1 as one of the most technologically advanced Monacos to date, and the blend of design, detailing, and manufacturing methods supports that claim. This isn’t merely an accessory; it’s an engineered statement piece with the attitude of a hypercar.
