Hermle 141-030 Clock Movement
The Hermle 141-030 clock movement is a little unusual as it is 14 day movement. It is spring driven amd it has a single gong on the half hour and the regular gong at the top of the hour. The equivilant Seth Thomas model is A208-012. As you are looking at the movement in the video, it takes a #11 spring barrel on the right and a #10 spring barrel on the left.
