Brief

In 1714, England's Parliament offered a reward to anyone whose method or device for measuring longitude proved successful. John Harrison imagined a clock that would withstand pitch and roll, temperature and humidity, and keep precise time at sea--something no clock had been able to do on land. This is the story of Harrison's 40-year effort to build his perfect timekeeper, known today as the chronometer.
