Measuring system for a plurality of mechanical horological movements

A case for testing a plurality of mechanical horological movements, each movement being provided with a winding button, the case comprising:

• a plurality of compartments, each compartment being configured so as to receive a movement, such that the movement is housed inside the compartment according to a predefined orientation,
• a plurality of microphones equal in number to the number of compartments, the microphones being mounted such that the winding buttons of the movements are located facing the respective microphones when the movements are housed inside the compartments according to said predefined orientation,
• wherein each microphone is provided with a noise-cancelling structure, such that disturbance of the acoustic measurements of each of the movements is minimized by noises produced by the adjacent movements, and
• wherein the case further comprises a PCB mounted beneath the compartments and including a board made of synthetic material, and wherein the microphones are mounted on or integrated into the board of the PCB.
