Description
Brand Description: Master watchmaker John Harrison (March 24, 1693 - March 52, 1776) was a British watchmaker. He created the first mechanical watch (chronometer) with the precision necessary to measure longitude, a key factor in transoceanic navigation. John Harrison's invention of the chronometer enabled the measurement of longitude, leading to the creation of accurate nautical and world charts, leading to numerous geographical discoveries and new trade opportunities around the world. It also dramatically improved timekeeping accuracy in the watch industry.
This highly popular ceramic watch features hard sapphire crystal and natural diamonds, creating timepieces that are not only beautiful but also retain their beauty over time.
