Kurt Klaus, an IWC icon, remains famous in watchmaking history for having invented the autonomous perpetual calendar. How did he do it? By imagining a 4-disc year display, a detail that allowed precise operation without any adjustment for a period of over 500 years! Born in St. Gallen, Switzerland, in 1934, Kurt Klaus began his career at IWC Schaffhausen in 1957 as a watchmaker in the after-sales service department. Between 1970 and 1999, he worked in the research and development department, developing a number of major innovations that enabled IWC to take its place at the forefront of the highly exclusive world of fine watchmaking. This special edition, with its 44-hour power reserve, was also produced in platinum, rose gold and white gold.
