About IWC Schaffhausen

Probus Scafusia

Since its founding in 1868 by American watchmaker Florentine Ariosto Jones, IWC Schaffhausen has stood out for uniting Swiss craftsmanship with modern engineering. Among its defining achievements are the creation of the iconic Pilot’s Watch and Portugieser, Albert Pellaton’s groundbreaking winding system and anti-magnetic technology, and the launch of the Ingenieur and Aquatimer families. IWC pioneered the use of titanium cases, introduced Kurt Klaus’s ingenious perpetual calendar, and achieved milestones like the Grande Complication and Il Destriero Scafusia. Today, as part of Richemont, IWC continues to distinguish itself through technical mastery, innovative materials, and timeless design.
