Charles LeRoy, Paris, verge watch circa 1780.
First published in 1788, this book gives a detailed description of how to make a verge watch movement.
The second edition of 1802 (provided here in translation) added an explanation of continental quarter repeaters and their faults.
This is my third translation on the topic of verge watch making. The previous two are available in the book Berthoud and Auch "How to Make a Verge Watch". All three authors treat the subject differently and Vigniaux's book complements that previously published.
The book has 176 pages (including 14 plates) and is arranged for double-sided printing. There is one colour illustration (page 125), but it can be printed in black and white.
