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.

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.
