The watch has a long and fascinating history, from a fifteenth-century status symbol of the rich and powerful to the mass-produced everyday timepiece of modern times. This book describes the main technical developments across a 500-year timespan, from the beginnings in Germany and France, through the golden age of English horology in the 18th century, to the development of modern factory production in America and Switzerland. It also sets out to give the general reader and collector a grasp of the key technological developments in watch and sets the lives of the inventors and artisans in the context of the social and economic history of their times. With over 290 photographs and 3D diagrams, this book includes an extensive listing and history of watch brands and manufacturers to assist in identification along with a useful glossary of terms.
