From their shapes to their movements, Cartier watches are unique. They are a timeless combination of the unexpected and the classic. This book recounts Cartier's constant quest for excellence in the production of complicated watches. From the Tortue single-pusher chronograph, created in 1929, to the Santos 100 skeleton watch, Cartier interprets complications in an inimitable way, always with a sense of design. Laziz Hamani's photographs immortalise these objects of exceptional technicality, while author and expert Jack Forster shares the spirit that drives every craftsman, engineer and artist to create the most extraordinary complicated watches.
