Product Review

This book, profusely illustrated in colour, takes the non-specialist reader through the detailed structure of the marine chronometer and explains its principles. It then guides the reader through the disassembly, cleaning, oiling and reassembly of marine chronometers, their rating, and preparation for transport, finishing with a substantial chapter on the evolution of the modern instrument. Some prominence is given to early French horolgists, who are often neglected in English language texts. There is no other book quite like it and, as clockmakers with actual experience of working on chronometers become rarer, this book will be of interest to collectors, horologists, curators and indeed anyone with an interest in the technology of time and navigation.
