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.
