From the cover: “There was intense rivalry and war among the British, French, Dutch, and Spanish in the 17th and 18th centuries for domination of the seas to protect their trading vessels and expand their empires. Every ship’s captain had the same problem: At sea, he could not establish his position within hundreds of miles to the East or West. The best solution seemed to be a clock to calculate how much the Earth had turned. It would have to be as accurate on a pitching and tossing sailing ship as a precision pendulum clock on shore.
Each nation offered inducements to inventors. In 1714 the British government put up prizes totalling £45,000, worth over £2m today. £20,000 was eventually won by a Yorkshire clockmaking genius whose first trade was carpenter. Over the years that followed, marine chronometers were developed and produced in large numbers. They are all collectors’ items in these days of radio and satellite navigation.
For many years Tony Mercer, grandson of the most enduring English maker, has studied and collected a huge amount of information about these remarkable instruments that enabled explorers and the Royal Navy to map the world, the Navy to police it, and merchant venturers to sail in relative safety. It would not be an exaggeration to say that the chronometer was one of the foundation stones of the British Empire.
The purpose of the chronometer is reviewed largely as a navigational aid for ocean-going vessels, but also for survey, medical and other activities calling for precise time measurement.
A complete chapter is devoted to John Harrison, rightly described as maker extraordinary, giving a fascinating insight into his lengthy efforts to produce a timekeeper that would satisfy all the requirements of the Commissioners of Longitude. Other great makers including John Arnold, Thomas Earnshaw, Le Roy, Berthoud, Frodsham, Dent, Kullberg and Tom Mercer are acknowledged for their evolutionary skills. Representative examples of chronometers and deck watches by international makers — from the earliest known to contemporary instruments — are illustrated in both colour and black and white.
A comprehensive List of Makers and Craftsmen brings together for the first time details of men who worked in the industry, their places of work and dates and serial numbers of their instruments. There is also an extensive bibliography.”
