John Harrison (1693-1776) war weder Seemann noch Uhrmacher, sondern Zimmermann. Dennoch wollte er die perfekte Uhr konstruieren - und so die Navigation revolutionieren.

Have you ever heard of the #HarrisonClock? What about a #Maritime #Chronometer?

In the 1700s #JohnHarrison, a carpenter -- not a horologist -- invented a clock that could keep time while at sea.

Such a thing seems trivial today but up until Harrison's clock such a feat had never been achieved before.

And why is it important to tell time while you're at sea?

So you can calculate your #Longitude.

What an amazing #story, and what an amazing #movie.
