Pendulum clock...

Pendulum clock ... that keeps time to within 5/8ths of a second in 100 days – based on a 250 year old design by John Harrison.  I read a biography of Harrison last year (fascinating!).  He never built a clock with this design, but he was ridiculed preemptively, toward the end of his life.  This is a complete vindication.
