Some partnerships are built on convenience. Others are built on something rarer: a shared obsession with making complicated things work beautifully. For IWC Schaffhausen and Mercedes-Benz, that obsession has now spanned 22 years, and it has just produced one of the most significant watches either company has ever put its name to.
To mark the 140th anniversary of the automobile, IWC has unveiled the Big Pilot's Watch Perpetual Calendar ProSet 140 Years Mercedes-Benz, a limited edition of just 140 pieces. It is not simply a watch with a famous badge on the dial. It is a mechanical manifesto, a statement of intent from two engineering cultures that have been speaking the same language for generations.
The modern automobile began with Carl Benz filing the patent for his motorwagen in 1886. Gottlieb Daimler followed shortly afterwards with his own motorised carriage. Within decades, both men's companies had merged, and the Mercedes-Benz star was born. The wristwatch, meanwhile, was evolving from a practical instrument into something far more ambitious: a miniature universe of gears and springs that could be carried everywhere. Both industries were attempting essentially the same trick: take an extraordinary number of tiny components, persuade them to work together with almost absurd precision, and make the whole thing reliable enough that an ordinary human being could use it without an engineering degree. The car gave us mobility; the watch gave us control over time. Eventually, both became something more. They became expressions of performance, craftsmanship and design.
That shared philosophy is what brought IWC and Mercedes-AMG together in 2004. In 2013, IWC became the Official Engineering Partner of the Mercedes-AMG PETRONAS Formula One Team. Since then, the relationship has produced special edition watches, motorsport experiences and collaborations inspired by some of Mercedes-Benz's most recognisable machines, including the legendary G-Class. Customers have been taken beyond the showroom and into the world of motorsport, from Formula One races to the gruelling 24 Hours of Nürburgring, as well as behind the wheel of Mercedes-AMG's most powerful sports cars.
The new watch is the culmination of all that shared history. At its heart is the Perpetual Calendar ProSet, one of IWC's most significant developments in mechanical watchmaking in decades. It rethinks one of traditional watchmaking's most complex complications by making its operation remarkably intuitive. The calendar can be adjusted both forwards and backwards through a single crown position, without additional pushers or complicated setting procedures. Behind that apparent simplicity lies an entirely mechanical system based on gears, protected by four patents. To manufacture the intricate components required, IWC employs LIGA, an advanced microstructuring technology based on lithography and electroforming.
The result is a calendar designed to make an inherently complex mechanism feel almost effortless to use. The watch displays the date, month, day and moon phase across four subdials, alongside IWC's signature four-digit year display. Its double moon-phase indication is accurate to within one day every 1,040 years, while the IWC-manufactured 82665 calibre provides a 60-hour power reserve. The 42mm stainless-steel case combines brushed and polished surfaces with a black dial, solid gold appliqués and gold-plated hands. A black rubber strap completes the utilitarian yet refined aesthetic, while IWC's EasX-CHANGE system allows for seamless swapping between compatible straps. On the sapphire-glass case back, the first joint logo of Daimler Motoren-Gesellschaft and Benz & Cie. commemorates not only the 140th anniversary of the automobile, but also the coming together of the two pioneering companies in 1926.
It first appeared at Watches and Wonders in Geneva earlier this year, where the industry got its first glimpse of what IWC had been working on. Now it arrives in a limited run of 140 pieces, each one embodying a year of pioneering innovation in the history of Mercedes-Benz.
Reflecting on the partnership, Chris Grainger-Herr, CEO of IWC Schaffhausen, says, "For 22 years, we have been part of the Mercedes-Benz brand universe – and what began as a partnership has grown into a friendship, built on mutual respect and deep admiration for each other's work. Our collaboration is rooted in shared values: a passion for world-class engineering, uncompromising performance, and visionary design. We warmly congratulate Mercedes-Benz on this company anniversary and look forward to many more years and more exciting projects together."
Mercedes-Benz is celebrating its anniversary under the theme "140 Years of Innovation". As part of that, three S-Class saloons are travelling to 140 selected locations worldwide, covering more than 50,000 kilometres across six continents, highlighting the brand's technology, heritage and global presence. Against that backdrop, IWC's watch feels less like a commemorative product and more like a natural extension of the same restless engineering spirit that has defined both companies for well over a century.
A watch and a sports car sit on opposite ends of the engineering spectrum. But both are ultimately machines designed to make performance feel tangible. And both, at their best, remind us that true luxury is not about what something costs. It is about what it took to make it.
