Abstract: A case configured to receive a plurality of mechanical watch movements in the wound state, each movement being housed inside a compartment, configured to receive and maintain the movement according to a predefined orientation. In this position, the winding buttons of the movements are positioned facing respective microphones which are mounted inside the case. The microphones are configured such that they cancel the noises detected, such that the acoustic measurements of each of the movements are essentially not disturbed by the noises produced by the adjacent movements. Also, a method for testing a plurality of mechanical movements installed in the case, and to a testing system which includes the case. The movements are measured by a plurality of cycles of consecutive and successive measurement periods.

Abstract: A portable device, and related method, that allows the values of one or more parameters characterising the operation of a mechanical watch to be measured. The device is provided with a contact microphone including a contact piece and a piezoelectric element. The contact piece is brought into physical contact with the case of a watch during a measurement period. The device further includes a power source, such as a rechargeable or replaceable battery, a microprocessor, a memory, and a screen for displaying the values measured, preferably a touch-sensitive screen. Preferably, the dimensions of the device are of a same order of magnitude as the case of a wristwatch. The device may have the shape of a horological eyeglass.
