Ships Clock

Ships Clock

 A ship clock that is precise and accurate enough to be used as a portable time standard; it can therefore be used to determine longitude by means of celestial navigation. When first developed in the 18th century it was a major technical achievement, as accurate knowledge of the time over a long sea voyage is necessary for navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man,john , spanning 31 years of persistent experimentation and test that revolutionized naval (and later aerial) navigation enabling the age of discovery and colonialism to accelerate.and the ships clock are now ready to use .they are maintaned as a gold cloclk
