Book Description
For many years, Tony Mercer, grandson of the most enduring English maker, has studied and collected a huge amount of information about marine chronometers, instruments which enabled explorers and the Royal Navy to map the world, the Navy to police it, and merchant venturers to sail in relative safety. 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. Representative examples of chronometers and deck watches by international makers--from the earliest known to contemporary instruments--are illustrated in both color and black and white. A comprehensive list of makers and craftsmen brings together details of men who worked in the industry, their places of work, and dates and serial numbers for their instruments.

Book Description
The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Book Description
The Marine Chronometers at Greenwich is the fifth, and largest, of the distinguished series of catalogues of instruments in the collections of the National Maritime Museum. Housed at the Royal Observatory Greenwich — the 'home of time' and the Prime Meridian of the world — this extraordinary collection, which includes the celebrated marine timekeepers by John Harrison (1693-1776), is generally considered to be the finest of its kind in existence. The book is however much more than just a catalogue, and includes an accessible and engaging history of the chronometer, revealing why these instruments were important in our scientific and cultural history, and explaining, in simple terms, how they worked and were used. A comprehensive Glossary and Bibliography are included to ensure any technicalities are explained and that the reader has suggestions for useful 'further reading'. Over 480 photographs and illustrations, including many fine macro-photographs and line drawings, illustrate the 'jewel-like' beauty of the chronometer's construction and explain the function and subtleties of its mechanism. A chapter on 'How the Chronometer was Made', describes the fine sub-division of labour used to create these special machines, from bare metal, right up to delivery on board ship, and brief biographies of the makers tell the human story behind this important nineteenth-century industry. Another chapter, 'The Evolution of the Chronometer', aimed at collectors, historians and curators, provides clearly structured information on assessing and dating the chronometer, something many find difficult. And, for the dedicated specialist, there is extensive tabulated data on the technical structure of this important collection, a unique resource for future research.

Book Description
Maritime chronometers are rare and precious items, crafted with care and precision, to provide an accurate means of measuring time and determining longitude at sea. Developed in the eighteenth century, these beautiful instruments were produced for the next two hundred years to the same design, and played a significant role in the growth of maritime trade, ultimately helping to shape the world as we know it today. In The Marine Chronometer, the author explains the workings of the chronometer and highlights some of the most significant makers and provides hints for maintenance. Topics covered include: -The problem of longitude -The early sea clocks -Developments in France and England -The mechanism of the chronometer -Caring for chronometers AUTHOR John Cronin studied horology at Bradford Technical College, where he was awarded a gold medal and a British Horological Institute prize for the national exams, before being elected to Fellowship of the Institute. John was the winner of the 1994 Artist Craftsman competition of the Worshipful Company of Clockmakers and is now closely involved with ICON [the Institute of Conservation]. He is one of just ten horologists who have gained accreditation with the institute as professional conservators, and is the only member specializing in chronometer work. SALES POINTS * Provides a comprehensive history of this intriguing piece of navigational equipment * An invaluable reference work for maritime history enthusiasts and clock collectors * Explains the working of the chronometer and provides hints for care and maintenance * Superbly illustrated with 146 colour photographs * John Cronin is a Fellow of the British Horological Institute and is one of only ten horologists with the Institute of Conservation ILLUSTRATIONS 146 colour photos *

Book Description
This survey of the rise and decline of English watchmaking fills a gap in the historiography of British industry. Clerkenwell in London was supplied with 'rough movements' from Prescot, 200 miles away in Lancashire. Smaller watchmaking hubs later emerged in Coventry, Liverpool, and Birmingham. The English industry led European watchmaking in the late eighteenth century in output, and its lucrative export markets extended to the Ottoman Empire and China. It also made marine chronometers, the most complex of hand-crafted pre-industrial mechanisms, crucially important to the later hegemony of Britain’s navy and merchant marine. Although Britain was the 'workshop of the world', its watchmaking industry declined. Why? First, because cheap Swiss watches were smuggled into British markets. Later, in the era of Free Trade, they were joined by machine-made watches from factories in America, enabled by the successful application to watch production of the 'American system' in Waltham, Massachusetts after 1858. The Swiss watch industry adapted itself appropriately, expanded, and reasserted its lead in the world’s markets. English watchmaking did not: its trajectory foreshadowed and was later followed by other once-prominent British industries. Clerkenwell retained its pre-industrial production methods. Other modernization attempts in Britain had limited success or failed.
