1. A method of transmission by a watch of an information message relating to an assessment of sleep quality of a user of said watch, the method comprising:
determining whether a sleep period of the user has started based on whether light intensity measured by a sensor of the watch is below a threshold value for a predetermined period of time and whether an ambient noise level measured by a sensor of the watch is below a threshold value for a predetermined period of time, the determining being performed during a specific time of day when the user is expected to fall asleep, without being performed during another time of the day when the user is not expected to fall asleep;
in response to determining that the sleep period of the user has started, recording, by processing circuitry of the watch, data describing at least one event-driven episode of at least one type of environmental event recorded during the sleep period of the user;
identifying, by the processing circuitry of the watch, at least one type of environmental event that disturbs the user's sleep by processing said descriptive data;
receiving, via an interface of the watch, the interface including a hybrid display dial, which includes an analog display and a digital display, an input from the user of a self-sleep assessment indicating the user's own assessment of the user's sleep, the self-sleep assessment including a good night sleep, a restful night sleep, or a difficult night sleep, the input being provided via the digital display of the hybrid display dial of the watch;
estimating, by the processing circuitry of the watch, a sleep quality assessment index for the user as a function of a sleep disturbance indicator for each identified type of sleep disturbing environmental event and the self-sleep assessment indicating the user's own assessment of the user's sleep, the self-sleep assessment including the good night sleep, the restful night sleep, or the difficult night sleep; and
generating, by the processing circuitry of the watch, a two-dimensional or three-dimensional graphic representation of the information message including the estimated assessment index for diffusion to the user.
