Dealing with a complicated watch used to be a rare job for the watch repairer, but with the popularity of the automatic, it is almost commonplace. Furthermore, the increased interest in calendar work, alarm watches, and chronographs will undoubtedly bring more and more complicated work into the workshop. This book deals with complicated work essentially from the repairer's point of view. The action of each mechanism is briefly and clearly described, dismantling and assembly instructions are given, as well as oiling charts and hints on fault-finding and their rectification.
