Kurt Klaus ( born in 1934 ) is a master watch maker and movement designer/producer working within IWC Schaffhausen since 1956. Besides wrist watches, the master watch maker also works on wall clocks as well.
One of his famous designs is the perpetual calendar module ( created for IWC ) which requires no further setting for 500 hundred years and can be operated through one single crown only.
IWC launched different versions of Da Vinci Perpetual model as a tribute to Mr.Klaus. The No.1 edition of the Platinum series is being used by Kurt Klaus personally.
