TAG Heuer’s Latest Monaco is an Impressive Achievement in Additive Manufacturing
Dubai Watch Week is upon us, and TAG Heuer is using it as a launching pad for for a new version of what is objectively one of the most impressive watches they’ve ever made. The Monaco Split-Seconds Chronograph Air 1 builds on the Monaco Split-Seconds that was introduced at Watches & Wonders in 2024. That one, you’ll recall, had a movement fashioned largely from titanium and weighed in at just 85 grams. The retail price at the time was a head scratching CHF 135,000, but it was also an incredibly impressive caliber and feat of engineering. Rattrapante chronographs like this are indeed quite rare, and certainly one with a caliber made of titanium is unheard of and adds additional layers of complexity to whole endeavor. The new Air 1 version of the watch is still 85 grams, but it achieves that weight even with new solid gold components in the case. The design of the case, still in the iconic Monaco square, has been substantially reworked and inspired by design and manufacturing processes that are part of the Formula 1 landscape. The case has effectively been hollowed out, with intricately skeletonized case flanks designed to maximize the weight to performance ratio. TAG Heuer achieves this through a process they refer to as Selective Laser Melting (SLM). This is an additive manufacturing process that is typically applied in aerospace, medical, and automotive manufacturing, and like other forms of 3-D printing it’s essentially a cheat code in achieving otherwise impossi...
