Wrist chronographs are mechanical wristwatches that, in addition to their normal clockwork, have a mechanism that allows them to time short-term events. They are one of the most popular collecting areas in the broad spectrum of wristwatches because they are not yet too expensive and are available in large numbers. Until now they have not been studied systematically. Now Land and Meis offer this outstanding identification book.The text deals with the dial of the chronograph and all the indications that can possibly be read from it. There is also a technical section that shows the historical development of the chronograph mechanism. With collectors in mind the authors have arranged the illustrations by the indications on the dials. Pictures of the movements are always included with those of the chronographs.This book is a particularly useful identification book for collectors, dealers, and auction houses.
