An assembly (1) for measuring a relative humidity level inside a watch (2), the watch (2) provided with a movement (10) and a device (4) for determining the humidity level present in the enclosure (9) of a case (3) of this watch (2). The determination device (4) includes a receiver module (6a, 6b, 6c) for receiving at least one acoustic signal from a timepiece component (11) of said movement (10), and a control unit (7) connected to said receiver module (6a, 6b, 6c). The control unit (7) is configured to run a model for evaluating a water vapour content of a gaseous fluid contained inside the enclosure (9) based on the at least one acoustic signal received by the receiver module (6a, 6b, 6c).

A device (1) for measuring a relative humidity level inside the enclosure (9) of a case (3) of a watch (2), the device (1) including: an emitter module (5) provided with a source of light radiation capable of emitting light beams (8) towards the enclosure (9) of the case (3); a receiver module (6a, 6b, 6c) for receiving at least one acoustic signal (12) from the enclosure (9), and a control unit (7) connected to the modules (5, 6) and which is configured to evaluate the water vapour content of a gaseous fluid (11) contained inside the enclosure (9) as a function of the at least one acoustic signal (12) received by the receiver module (6a, 6b, 6c).

An assembly (1) for measuring a relative humidity level inside a watch (2), comprising the watch (2) and a device (4) for determining the humidity level present in the enclosure (9) of a case (3) of this watch (2), the determination device (4) comprising a free space optical system and a control unit (7). The system includes: an emitter module (5) for emitting at least one light beam (8); and a receiver module (6) for receiving the at least one light beam (8); the control unit (7) being connected to the modules (5, 6) and the at least one light beam (8) emitted by the emitter module (5) defining an optical path partly comprised in the case (3) and extending as far as the receiver module (6) and the control unit (7) being configured to evaluate the absorption of the light beam (8) by the water vapour capable of being present inside the enclosure (9) of the case (3).
