IW393101 IWC Da Vinci Tourbillon Retrograde Chronograph

£ 91000 In stock
Uniting complications such as a chronograph, a tourbillon and a retrograde date display on an IWC dial for the first time called for a redesign of the IWC-manufactured 89900 calibre. A fully fledged tourbillon was integrated to replace the small seconds at “6 o’clock”.
