From the late 19th century into the 20th, and all the way through to the 21st century, IWC has been developing its own unique vocabulary for watchmaking and technologies that have helped and challenged the collective industry to better itself. Take, for example, the Pallweber system of displaying digital hours and minutes and IWC technical director Albert Pellaton’s idea to use a soft inner iron core to provide magnetic protection and his automatic winding system. Some of the first instances of the use of titanium and ceramic in watchmaking can be attributed to IWC. And you can’t discuss IWC’s many accomplishments without bringing up Kurt Klaus’s Grande Complication, which was built on a Valjoux 7750 ébauche and boasted the ability to adjust all the calendar displays by turning the crown backwards and forwards.
