IWC Schaffhausen has achieved a remarkable honour, winning the prestigious “Aiguille d’Or” at the 24th Grand Prix d’Horlogerie de Genève. Known as the “Oscars®” of the Swiss watch industry, this award celebrates the very best in watchmaking. The winning piece, the Portugieser Eternal Calendar, is a true masterpiece that blends beauty and innovation.

Launched earlier this year, the Portugieser Eternal Calendar is IWC’s first watch to include a secular perpetual calendar. This means it is designed to follow the complex rules of the Gregorian calendar, which skips three leap years every 400 years. Thanks to a specially designed 400-year gear, the watch makes these adjustments automatically, ensuring accuracy for centuries without needing manual correction.

What makes this watch even more extraordinary is its moon phase display. It has set a world record for precision, remaining accurate for an incredible 45 million years. This feature is not just a technical achievement; it’s a poetic reminder of how time connects us to the universe.

Winning the “Aiguille d’Or” is the highest recognition in the watchmaking world. It shows IWC’s ability to combine timeless elegance with cutting-edge technology. The Portugieser Eternal Calendar is not just a tool for telling time—it’s a work of art, a symbol of human ingenuity, and a testament to what can be achieved when tradition and innovation come together.

This award highlights IWC Schaffhausen’s place among the greats of watchmaking. The Portugieser Eternal Calendar is a reminder that some creations are not just made to measure time but to stand the test of it.
