This book is a lucid and authoritative catalog of man's obsession with time and timepieces. Hundreds of full-color and black-and-white illustrations compliment intricate line drawings that illuminate the inner workings of these devices.

In Marking Modern Times, Alexis McCrossen relates how the American preoccupation with time led people from across social classes to acquire watches and clocks, and expands our understanding of the ways we have standardized time and have made timekeepers serve as political, social, and cultural tools in a society that not merely values time, but regards access to it as a natural-born right.

Traces the art of clockmaking from the era of handcrafting to present-day automation.

"The Mechanics of Mechanical Watches and Clocks" presents historical views and mathematical models of mechanical watches and clocks. Although now over six hundred years old, mechanical watches and clocks are still popular luxury items that fascinate many people around the world. However few have examined the theory of how they work as presented in this book. The illustrations and computer animations are unique and have never been published before. It will be of significant interest to researchers in mechanical engineering, watchmakers and clockmakers, as well as people who have an engineering background and are interested in mechanical watches and clocks. It will also inspire people in other fields of science and technology, such as mechanical engineering and electronics engineering, to advance their designs. Professor Ruxu Du works at the Chinese University of Hong Kong, China. Assistant Professor Longhan Xie works at the South China University of Technology, China.

A history of timepieces made in Pennsylvania from William Penn's time to the present, this book is more than a compendium of clock and watchmakers and their work. With abundant illustrations and lore from historians in every part of the state, it recreates a time when clock and watchmaking was not a mere occupation: it was truly a craft. The author attributes this characteristic to the Keystone State's unusually varied population, and explores the various "old world" influences affecting the design and style of timepieces. The story of clock and watchmaking from colonial Philadelphia to Pittsburgh's Golden Triangle is a major chapter in the history of industry, trade, tastemaking, and craftsmanship. Clocks of finely carved wood decorated the homes of prosperous early settlers, and golden watchcases adorned their persons; meanwhile, clocks on Independence Hall and other public buildings measured the hours for the general citizenry. As time passed, more utilitarian clocks graced schools and factories, while Hamilton watches kept the trains running on time. Resisting the temptation to lower standards for the sake of mass production, Pennsylvania clock and watchmakers gained fame for their high-quality craftsmanship. The making of clocks and watches is detailed by Dr. Gibbs from its beginning in the southeastern counties of William Penn Country, through the Pennsylvania Dutch Country and the center of the Commonwealth, and on to the state's northern and western frontiers. The craftsmen are presented in historical context, with emphasis on their social and educational backgrounds and the effect of these on their timepieces. Separate sections focus on illustrious clockmakers such as the Ellicott and Solliday families, Jacob Detweiler Custer, and the master of horology and astronomy, Dr. David Rittenhouse. Pennsylvania Clocks and Watches is an indispensable handbook for the experienced collector and a stimulating guide for the beginner. It is also a valuable reference for students of industrial and social history, design, and folkways.

This book includes detailed instructions for making all types of escapements and for the location and correction of faults. The book is designed to appeal to those interested in the mechanisms of clocks and watches.
