The movement is driven by two spring barrels with fusees and has a duration of eight days. It is being regulated by verge escapement in combination with a short pendulum. The clock has Dutch half hour rack striking on two alternating bells with repeating on demand. It has a pull wind alarm on the large bell. The back plate has fine foliate engraving.
