The Marine Chronometer and John Harrison - a brief history 

We embark on a journey into the history of the marine chronometer, a device that was indispensable to navigation on the open seas. By providing an accurate and reliable source of time on ocean voyages, it allowed mariners to determine their exact longitude, something that was difficult before its invention. We also explore the life and legacy of John Harrison, the man behind the first successful marine chronometer, and his ups and downs towards this achievement and beyond.
