In a bold move that underscores its commitment to innovation and style, TAG Heuer has unveiled the Monaco Split-Seconds Chronograph Air 1 at Dubai Watch Week 2025. This latest iteration of the iconic Monaco series is not only the lightest ever produced but also one of the most technologically advanced watches in the brand’s 165-year history.
The Monaco Split-Seconds Chronograph Air 1 represents a significant leap in watchmaking, combining cutting-edge materials and complex engineering to deliver a timepiece that is both lightweight and visually striking. Weighing in at just 85 grams, this watch is a testament to TAG Heuer’s expertise in materials science and high complication design.
Revolutionary Case Design
The case of the Air 1 is unlike any other Monaco before it, featuring a futuristic design that draws inspiration from the world of hypercars. With its sharp angles and aggressive aesthetics, the watch resembles a Lamborghini, a fitting comparison given TAG Heuer’s partnerships with Red Bull Racing and Porsche.
This unique design is achieved through a process known as selective laser melting (SLM), an additive manufacturing technique akin to 3D printing. While SLM is commonly used in industries such as aerospace and Formula 1, TAG Heuer has adapted it for watchmaking, allowing for the creation of complex geometries and a distinctive hollowed-out appearance.
“The effect is that the TAG Heuer Monaco Split-Seconds Chronograph Air 1 appears to have been hollowed out, as if designed with speed and airflow in mind, so that it looks like it could have been conceived in a wind tunnel,” explains TAG Heuer.
The watch’s case incorporates solid 18k 2N yellow gold components, including the split-seconds pusher and honeycomb inlays, further enhancing its luxurious appeal. Despite its substantial size—41mm in diameter and 15.2mm thick—the Air 1 feels surprisingly light on the wrist, thanks in part to the extensive use of sapphire crystal in its construction.
High-Tech Dial and Strap
While the case sets a new standard for innovation, the dial of the Air 1 maintains the open design characteristic of previous Monaco Split-Seconds models. Featuring two arching structures that house the subdials, the dial is both airy and high-tech, with a monochromatic color scheme accented by gold lacquer highlights.
The strap, a hybrid of black rubber and Alcantara, continues the high-performance theme. Its honeycomb lattice pattern is reminiscent of materials found in high-end sports cars, and a black DLC titanium butterfly folding clasp ensures a secure fit.
Precision Movement
At the heart of the Monaco Split-Seconds Chronograph Air 1 is the calibre TH81-00, TAG Heuer’s first mechanical split-seconds chronograph movement. Co-developed with Vaucher Manufacture Fleurier, this movement is the lightest ever produced by TAG Heuer, weighing just 30 grams.
The TH81-00 offers a robust 65-hour power reserve with the chronograph function off and 55 hours with it on. Its chequered flag finish and unique rotor, featuring a honeycomb pattern in gold lacquer, are hallmarks of TAG Heuer’s high-end craftsmanship.
Market Impact and Future Prospects
The introduction of the Monaco Split-Seconds Chronograph Air 1 marks a significant moment for TAG Heuer, showcasing the brand’s ability to push the boundaries of traditional watchmaking. As the industry continues to explore the potential of additive manufacturing, TAG Heuer’s use of SLM could pave the way for further innovations.
Limited to just 30 individually numbered pieces, the Monaco Split-Seconds Chronograph Air 1 will be available from December 2025 at TAG Heuer retailers, priced at CHF 150,000. This exclusive release is likely to attract collectors and enthusiasts eager to own a piece of horological history.
As TAG Heuer continues to innovate, the watchmaking world will be watching closely to see how the brand and its LVMH affiliates leverage these new technologies in future designs. The Monaco Split-Seconds Chronograph Air 1 is not just a watch; it’s a bold statement of what’s possible when tradition meets innovation.
