Is Patek Philippe's shell number consistent with the movement?

Inconsistent. Patek Philippe's body number and movement are two important parts of a watch. The body number represents the appearance of the watch, including the dial, case and strap, and the movement is the heart of the watch, which is responsible for driving the whole watch. Patek Philippe's case is engraved with its unique number, which can be used to find its model and production year. Patek Philippe's movement is very rich in functions, and each series has its own unique functions. So the shell number and the movement are not necessarily the same.
