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.

A dynamic chronometric testing of a movement or of a watch, control device fine controlling a predefined or random cycle of movements via standardised chronometric testing positions, the rate parameters are also measured in dynamic positions where the acceleration and velocity are different to zero and which correspond to additional dynamic chronometry criteria, defined to qualify the rate during a continuous movement applied to the movement or respectively to this watch.

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.

A watch packaging box including a base containing a removable tray, a lid cooperating in a complementary manner with the base to close the box, the tray including compartments for receiving a watch, each delimited by a bottom and a partition, the box including, centred inside each compartment, a resilient pad pressed onto a watch by the lid in the closed position, and the box includes, in each compartment, a main orifice for passage of a sensor or tool, included in a device performing a watch testing and/or timing method, on the watch occupying the compartment, and each resilient pad includes a secondary orifice aligned with a main orifice for access of the sensor or tool to the watch.

A watch winding device includes a motor driving a winding operation, an acoustic measurer of the oscillator of a watch in the winding position, and a controller analysing the signals transmitted by the measurer and comparing them to desired values that can be parameterized to regulate the operation of the motor by starting this motor when the operating amplitude of the oscillator is less than a minimum value, and by stopping this motor when the working amplitude is higher than a maximum value, these acoustic measurers are fixed in a base behind an sensing opening of the acoustic sensor. The device includes an acoustic duct which places a receiving port, located inside a chamber for housing a watch, in communication with a transmitting port movable by the motor facing this sensing opening.

A method for optimising an operation of setting and winding a watch or the timepiece movement thereof including initially making a measurement of the operation of the watch or of the timepiece movement followed by an activation of an operation of low-amplitude reciprocating movements of the watch or of the timepiece movement on said jig of the device, or initially implementing an activation of an operation of low-amplitude reciprocating movements of the watch or of the timepiece movement before making a measurement of the operation of the watch or of the timepiece movement, and resuming low-amplitude reciprocating movements in phase or a synchronisation step being implemented at the end of the first two steps. The first oscillating signal of movements includes a change in sign of the absolute rotation speed in each successive oscillation period, the oscillating signal having a positive part and a negative part of the operating speed.
