Cartier's most famous and complicated watches and a new never published before collection. From their forms to their movements, Cartier watches are unique. They are an enduring combination of the unexpected and the classical. This book chronicles Cartier's constant quest for excellence in the manufacture of complicated watches. From a Tortue single push-piece chronograph, created in 1929, to a contemporary Santos 100 skeleton watch, Cartier interprets complications in its own inimitable way, always with a sense of design. Laziz Hamani's photographs capture these objects of exceptional technicity while author and expert Jack Forster shares the spirit that motivates each craftsman, engineer and artist to create the most stunning complicated watches.
