Now for IWC’s “Grande Complication” timepiece : do you want the 659 parts or the 240 pages ? The question is worth asking because this masterpiece of mechanical ingenuity requires no less than 659 components to perform its 12 functions and it now comes with its own 240-page book relating and describing the technical exploits involved in its construction. It is the first time ever that the design of a watch has been accompagnied by such complete documentation, which even a layman can understand. For those who want moving pictures along with memorable words, IWC has produced a 20-minute video cassette featuring : the “Grande Complication” on the wrist.
