The movement of this watch is the rare barillet-type with pinned cylinder, a miniature version of the type of movements found in full-size musical boxes. Most makers during the early 19th century used the sur-plateau type movement with a flat pinned rotating disc as opposed to a cylinder. The cylinder type is more robust and gives a more resonant sound, but requires a thicker case to house it.
