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.
