Rewriting the Rules: The TAG Heuer Monaco Split-Seconds Chronograph Air 1 Arrives

Date: November 19, 2025

TAG Heuer just dropped a revolution at Dubai Watch Week 2025: the Monaco Split-Seconds Chronograph Air 1. This isn't just a new watch; it's a statement on the future of case architecture and high-performance horology. Limited to just 30 pieces, this avant-garde timepiece represents one of the most complex and visionary creations the Swiss watchmaker has ever produced.

Born of Air: A Hypercar-Inspired Case

The most immediate and striking element is the case. Inspired by the aerodynamic world of hypercars and Formula 1, the Monaco Split-Seconds Chronograph Air 1 looks like it was literally sculpted by the wind.

• Additive Manufacturing: The case is crafted from Grade-5 titanium using Selective Laser Melting (SLM). This 3D-printing technique, adapted from aerospace engineering by the TAG Heuer LAB, allows for intricate, hollowed, and architectural structures previously impossible with traditional machining.

• Featherlight: The resulting watch weighs an astonishingly light 85 grams, channeling the energy and flow of motorsport design.

• Visual Flair: The detailed twin-layered honeycomb mesh—reminiscent of high-performance engine covers—is accented by touches of 2N yellow gold and black DLC-coated titanium, creating a stunning contemporary aesthetic that immediately sets it apart from any previous Monaco.

The Engine: Calibre TH81-00 Rattrapante

A revolutionary case demands a revolutionary movement. Beating at the heart of the Air 1 is the Calibre TH81-00, developed in collaboration with Vaucher Manufacture Fleurier.

This is officially TAG Heuer’s most complex chronograph movement to date.

• Split-Seconds Power: The high-frequency automatic movement features the legendary rattrapante (split-seconds) function, allowing the user to measure two separate intervals simultaneously.

• Lightweight Core: The movement itself utilizes numerous lightweight titanium components, marrying strength and finesse.

• Racing DNA: Through the sapphire caseback, you can admire the Calibre TH81-00, complete with a checkered-flag finishing—a beautiful mechanical tribute to TAG Heuer’s enduring connection to racing.

The Avant-Garde Legacy Continues

From the groundbreaking Heuer Mikrograph in 1916 to today's modern Masterpieces, TAG Heuer has consistently pushed the limits of precision.

As CEO Antoine Pin stated, the Air 1 is a "watchmaking revolution." The use of the SLM process has essentially delivered a designer’s wildest creation, marking a new chapter for the brand and the iconic square-cased Monaco.

The TAG Heuer Monaco Split-Seconds Chronograph Air 1 is elegant, powerful, and visionary—it’s not just a watch, it’s a concept realized, and it marks the beginning of a new series of conceptual timepieces for the brand.
