This is a clock I design back in my mecanical ingeneering degre as a personnal challenge.The gears are laser cut.The pendulum keep and accurate swing per second in pair with a graham escapement mecanism.A weight and a counter weight keep the clock running for about 8 days.To rewing the clock, genly pull the counter weight down while lifting the weight up.A ratcheting gear to ajust time forward and back.Lead is used inside the weights and pendulum.The general inspiration come from the Gothic periode.
