Hey everyone, check this out. It's a clock made from John Harrison's 240 year old plans by
clockmaker Martin Burgess. The pendulum clock was designed to be accurate to within a
second over a 100 day period, and would use no lubrication in doing so.

After it's completion, the clock was tested for 100 days, and was only 5/8 of a second off.
It even could measure barometric pressure, and was 96% accurate with that.

Here is the article for you...
