Abstract: A method transmits by a watch an information message relating to an assessment of the sleep quality of a user of the watch. The method includes the following steps: recording by the processing unit of data describing at least one event-driven episode of at least one type of environmental event recorded during a sleep period of the user; identifying at least one type of environmental event that disturbs the user's sleep by processing the descriptive data; estimating 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 devising an information message including the estimated assessment index for the purpose of diffusion to the user.

Abstract: A method controls access to at least one confidential datum archived in a memory element of a watch. The memory element includes general data and confidential data, the access to which by a function of the watch requires the wearer of the watch to be identified. The method includes authenticating the wearer to grant access to the functions of the watch, selecting one of the functions of the watch requiring the use of at least one of the confidential data or general data archived in the memory element, determining the category to which the at least one datum required by the function belongs, verifying the identity of the wearer based on an interaction between the wearer and a graphical representation included in the watch, and authorizing use of the at least one confidential datum by the function when the identity of the wearer has been verified.

Abstract: A method controls access to at least one confidential data access to which by a function of a watch requires an identification of its wearer. The method includes authenticating the wearer of the watch to authorise access to the functions of this watch, selecting one of the functions of the watch requiring the use of at least one of the confidential or general data archived in the memory element, determining the category to which the at least one data required by the function belongs, verifying the identity of the wearer of the watch from at least one biometric information element comprised within a portion of the skin of this wearer when the at least one data is the confidential data, and authorizing use of the at least one confidential data by the function as soon as the identity of the wearer of the watch is verified.

Abstract: A watch whose watch case includes a case middle and a rotating bezel provided with a bezel locking system. The system includes a rotating crown secured to an arbor, the arbor being arranged inside a radial hole in the case middle. By rotating the crown, the user can screw or unscrew the arbor with respect to the hole. The arbor includes a frustoconical section which interacts with a pin mounted perpendicularly to the arbor and returned towards the arbor by a spring. Screwing the arbor into the hole will cause the frustoconical section to push the pin into a receiving space provided on the lower surface of the bezel, which locks the bezel. Unscrewing the arbor automatically releases the pin from the receiving space by the return force exerted by the spring. The crown can include a helium valve mechanism.

Abstract: A method for facial authentication of a wearer of a watch includes: initiating an authentication process including detecting at least one triggering movement/gesture carried out by the wearer; capturing at least one sequence of images relative to the face of the wearer pivoting from one direction to another in front of the optical sensor; acquiring surface geometric data of the face associated with each image of at least one sequence; generating a three-dimensional model of the face of the wearer from at least one captured sequence of images and from the acquired geometric data; determining an identification index generated based on identification data relative to a plurality of features characteristic of the face of the wearer of the watch detected on the basis of the three-dimensional model, and identifying the wearer if the identification index is greater than a reference identification index.

Abstract: A method for managing the use of the functions of a watch including a step of authenticating the wearer of the watch in order to authorize access to the functions, and a step of controlling the identity of the wearer of the watch at a determined period by verifying the validity of a digital identification element determined from at least one biometric information element of the wearer, and a step of unlocking access to the functions of the watch when this access has been locked, the step including the following sub steps: presentation of a graphic representation on an interface for broadcasting a visual piece of information of the watch; selection within a limited time interval of a sequence of at least two identification portions comprised in the graphic representation aiming at identifying the wearer, the sequence corresponding to an identification code of the wearer, and validation of the selected sequence.

Abstract: In a method for monitoring or tracking between mobile devices of a same group, mobile devices broadcast messages in broadcast mode over a radio interface in compliance with a short-range digital communication protocol. The messages can be received by all other mobile devices in the vicinity and can communicate according to the protocol. The messages include encrypted data encrypted using at least one identifier of the emitter device and a seed intended for single use or having a short period of validity. The encrypted data can only be decrypted by a limited group of devices. The mobile devices receive messages broadcast by other devices and decrypt the messages intended for a group to which they belong. If the protocol provides that the message includes an address field of the emitter device, this field is filled with a randomised address intended for single use or having a short period of use.

Abstract: A method for managing the electrical consumption of a watch including a step of identifying a need to charge an accumulator of the watch, and a step of charging the accumulator through guided actuation of a control member of an electrical energy generation mechanism of the watch, if a need to charge is identified.

Abstract: A method for securing access to a watch (100) including: authentication (10) of the wearer of the watch (100) with a view to authorising access to the functions of this watch (100) based on an interaction between the wearer of the watch and a graphic representation included in the watch (100), and periodic checking (20) of the identity of the wearer of the watch through a verification of the validity of a digital data item determined based on at least one biometric data item of the wearer of said watch with a view to retaining/removing the authorisation for access to the functions.

Abstract: An aspect of the invention relates to a method for correcting magnetometric measurements (10) made by a magnetometer mounted on a mobile support. The mobile support carries one or more movement and/or position sensors fixedly mounted with respect to the magnetometer.

Abstract: A smartwatch including a first screen cooperating with a first display management device of said smartwatch contributing to broadcasting information pertaining to functions provided by the smartwatch and a second screen that is separate from the first screen cooperating with a second display management device of the smartwatch contributing to broadcasting information concerning all or part of a visual message pertaining to a visual and/or audio animation occurring within an environment wherein the smartwatch is located, the information being transmitted from a display control server controlling the second display management device of the smartwatch.

Abstract: An analogue information display system for a watch provided with a mechanical movement includes a display dial including a plurality of apertures, a moving display part supporting graphical representations, disposed in such a way that the graphical representations supported thereby appear in the plurality of apertures in order to generate the information, and an indicator member configured so as to designate a piece of information generated in an aperture to be notified to the wearer of the watch.
