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 transmitter-receiver includes an electronic chip a mixer for mixing the frequency of a received radio frequency signal with that of an oscillating signal supplied by a first frequency synthesizer in, a switch having two inputs connected to an output of the mixer and to an auxiliary input terminal, a filter and gain stage connected to the output of the switch, and a modulator-demodulator connected to the output of the filter and gain stage. The first frequency synthesizer is connected between the output of the modulator-demodulator and radio frequency input and output terminal, and configured to supply a frequency-modulated signal to the radio frequency input and output terminal. The electronic chip further includes a second frequency synthesizer connected between the output of the modulator-demodulator and an auxiliary output terminal, and configured to synthesize a modulated low-frequency signal supplied by the auxiliary output terminal, whereby the center value of the low frequency is equal to the value of the intermediate frequency.
