Pocket-Watch Slide Rules

This book is about one of the most attractive and tactile forms of slide rules, the pocket-watch slide rule. Although pocket-watch slide rules were not the most accurate nor easy to use, these delightful devices were in makers catalogues from all parts of the world for the last century of the slide rule's life. Pocket-watch slide rules are an exquisite example of the slide rule makers' art and are perhaps the most collectable type of slide rules.

The Book Includes:
-Detailed descriptions of over 150 pocket-watch slide rules and variants
-Hundreds of full-color illustrations, detailed descriptions, and dating information

-Approximately 80 makers and retailers from the UK, Europe, and the USA

-Descriptions of special scales used
-Coverage of seminal patents
-A glossary of terms
-A comprehensive bibliography
