The watch numbered 50 out of 100 – the last available – will be auctioned by international auction house Bonhams, with the proceeds going to Ignite, a joint charitable initiative operated by the Mercedes-AMG PETRONAS F1™ Team and Sir Lewis Hamilton to support greater diversity and inclusion in motorsport.

Christoph Grainger-Herr, CEO of IWC Schaffhausen

“Toto Wolff is the outstanding team principal of his  generation and the Mercedes-AMG PETRONAS F1™ Team has seen unprecedented success under his  leadership. Winning a race or a single championship  campaign are great achievements in their own right.  However, Toto’s ability to create a dynamic team driven  by a high-performance culture, has led to unmatched  consistency and eight consecutive constructors’ titles over  the last nine years of his tenure. We are proud to honour  this outstanding personality with a unique Big Pilot’s Watch, and once again join forces with our longstanding  motorsport partner in support of a good cause,”

Christoph Grainger-Herr, CEO of IWC Schaffhausen

In 2013, the Austrian entrepreneur and former racing driver Toto Wolff became a shareholder and executive director of the Mercedes-AMG PETRONAS F1™ Team. During his time as the Team Principal & CEO, the team has won eight consecutive constructors’ titles between 2014 and 2021 – more than any other team in elite world sport. With the Big Pilot’s Watch Perpetual Calendar Edition “Toto Wolff x Mercedes-AMG Petronas Formula One™ Team”, Wolff was finally honoured with an IWC watch that carries his name.

The Big Pilot’s Watch Perpetual Calendar Edition “Toto Wolff x Mercedes-AMG Petronas Formula One™ Team” (Ref. IW503607) features a Ceratanium® case and crown, a glass dial, and black hands. The printing and luminescence are in the team’s signature PETRONAS green colour. Limited to only 100 pieces, this watch is fitted with a black rubber strap with textile inlay. Ceratanium® is a ground-breaking new material developed by IWC. It is as light and robust as titanium and almost as hard and scratch-resistant as ceramic. Ceratanium® is based on a special titanium alloy forged explicitly for IWC. The case components are machined from bars and then treated in a furnace process at high temperatures. During this heat treatment, they develop not only ceramic properties on their surface but also their striking matte black finish.

“After almost a decade of partnership, it is an honour and a privilege to have been asked to design a watch with IWC Schaffhausen. For me, it had to be a Big Pilot’s Perpetual Calendar. The watch uses Ceratanium, a material that stands for robustness and strength, two features that are very important to me. The dial is in bold PETRONAS Green, the colour of our team, and, of course, I had to add a subtle red collar around the crown and pay tribute to our friend and colleague Niki Lauda. The final design is exactly how I had imagined it to be and I am delighted to donate this special timepiece to the auction and hope to raise as much as possible for the Ignite partnership,” states Toto Wolff, Team Principal & CEO of the Mercedes-AMG PETRONAS Formula One™ Team.


IWC’s legendary perpetual calendar was developed by former head-watchmaker Kurt Klaus during the 1980s. The mechanical program automatically recognises the different lengths of the months and the leap years, requiring no manual adjustment until 2100. The moon phase display shows the moon as seen from the northern and southern hemispheres and will only deviate by one day after 577.5 years. The calendar module is driven via a single nightly switching impulse by the IWC-manufactured 52615 calibre. This automatic movement features IWC’s iconic Pellaton winding system, which has been reinforced with ceramic components and accumulates a power reserve of 7 days in two barrels. The movement can be admired through the tinted sapphire glass back. 



The watch carrying the number 50 will be auctioned online by the international auction house Bonhams. The proceeds will go to Ignite. This charitable initiative launched in 2021 by The Mercedes-AMG PETRONAS F1™ Team and Sir Lewis Hamilton will focus its work on supporting greater diversity and inclusion in motorsport. The watch comes with a 10-minute video call with Toto Wolff and a tour of the Mercedes-AMG PETRONAS F1™ Team HQ and Operations Centre, offering exclusive, behind-the-scenes insight into what goes into designing, manufacturing and running the world’s most advanced racing cars.

In addition, IWC Schaffhausen and the Mercedes- AMG PETRONAS F1™ Team are also announcing the establishment of a yearly donation of 50,000 Euros, which will be funded by IWC. Like the auction proceeds, the funds will also go to Ignite. Learn more: Ignite Partnership Announces Inaugural Grants to Boost UK motorsport (

In 1868, the American watchmaker and entrepreneur Florentine Ariosto Jones travelled from Boston to Switzerland and founded the ‘International Watch Company’ in Schaffhausen. His visionary dream was to combine advanced American manufacturing methods with the craftsmanship of Swiss watchmakers to make the best pocket watches of his time. In doing so, he not only laid the foundation for IWC’s unique engineering approach but also established the centralised production of mechanical watches in Switzerland.

Over its 150 year history, IWC Schaffhausen has developed a reputation for creating functional complications, especially chronographs and calendars, which are ingenious, robust, and easy for customers to use. A pioneer in the use of titanium and ceramics, IWC today specialises in highly engineered technical watch cases manufactured from advanced materials, such as titanium aluminide and Ceratanium®. Preferring the principle of “form follows function” over decoration, the Swiss watch manufacturer’s timeless creations embody their owners’ dreams and ambitions as they journey through life.

IWC sources materials responsibly and takes action to minimise its impact on the environment, creating intrinsically sustainable timepieces that are built to last for generations. The company prides itself in training its own future watchmakers and engineers, as well as offering an excellent working environment for all employees. IWC also partners with organisations that work globally to support children and young people.
