The partnership between IWC Schaffhausen and the Mercedes-AMG Formula 1 Team has flourished since its inception in 2004, establishing a legacy of precision and performance that transcends both horology and motorsport. This collaboration signifies a blend of exceptional craftsmanship and high-speed engineering, culminating in timepieces that echo the relentless pursuit of excellence synonymous with the Mercedes-AMG brand. The IWC Big Pilot's Watch Perpetual Calendar Toto Wolff x Mercedes AMG Limited Edition (ref.

Crafted from IWC's proprietary Ceratanium, this watch showcases a robust 46.2 mm case that is lightweight yet durable, seamlessly combining the properties of ceramic and titanium for an exceptional finish. The striking grey dial features luminescent Arabic numerals, making it easy to read under varying conditions.

The watch is protected by a sapphire crystal with anti-reflective coating, ensuring clarity and durability while maintaining a water resistance up to 60 metres.

At the core of this remarkable timepiece lies the IWC-manufactured Calibre 52615 movement. This automatic movement boasts an impressive power reserve of 168 hours, supported by a rotor that features an 18-carat gold medallion. With a frequency of 28,800 vibrations per hour (4.0 Hz), the movement ensures exceptional accuracy. The watch is also equipped with a power reserve display, allowing the wearer to monitor the remaining energy. Additionally, the small hacking seconds feature enhances precision in timekeeping, showcasing the level of detail that IWC invests in its mechanical creations.

Completing the design is a comfortable black rubber strap with a textile inlay, designed for both sophistication and durability, secured by a titanium folding clasp. Limited to just 100 pieces, each meticulously numbered, this watch not only serves as a functional accessory but also stands as a coveted collector's item, merging the realms of motorsport heritage and horological artistry.
