This fascinating timepiece, dubbed the Quarderdeck Striker, is an electromechanical marvel designed and hand-built by John Hilgenberg, inventor of the air-driven Pneumachron.
It is a mechanical clock at heart — just look at all the wooden gears — but its functionality is supplemented with electric servos that drive the rolling odometer time display, the power-maintaining winding mechanism (which Hilgenberg believes is the first of its kind), and the nutcracker bell striker who tolls the naval time every 15. Check out the video for a full explanation of the mechanism’s inner workings from Hilgenberg himself. [Makezine]
