Technology background

[0003] Electronic watches such as so-called “connected” watches have established themselves in recent years in the watch industry. The setting of such a watch is conventionally carried out manually, in particular via the activation of push buttons, crowns and/or touch keys, which is relatively restrictive for the user or the after-sales service responsible for the setting. For example, if the watch has a perpetual calendar mechanism, the adjustment of the position of the analog display elements of the perpetual calendar mechanism, and more generally the adjustment of the perpetual calendar mechanism, can be carried out by pulling and /or turning a watch crown and/or by pressing one or more watch pushers. Thus, a type of year is selected (for example, leap year) and the various display elements are correctly positioned, and more generally all the elements of the perpetual calendar mechanism. Not only is this method tedious for the user, who must remember and perform all the adjustment operations correctly one after the other, but it also induces risks of errors and shifts.

Detailed description of the invention

In Figures 1 to 6 an electronic watch 2 such as a quartz watch comprising a case 4 is shown. Such an electronic watch 2 is designed to be configured during an adjustment method described below and this, in particular from a portable or mobile electronic device 3 . This method is suitable for adjusting a mechanism performing at least one function implemented by this watch 2. This function can be a horological function such as the perpetual calendar of a quartz watch 2. This watch function can also include the date, the day, the month, the current year, the current moon phase, etc. It should be noted that, alternatively, it can be any other function likely to be performed by this watch 2.

The method mentioned above is implemented by an adjustment system 1 of the watch 2. This system 1 therefore comprises the portable electronic device 3 as well as said watch 2, the two being capable of carrying out data exchanges 13 each other using near-field communication technology.

[0014] In this context, the watch 2 then comprises in a non-limiting and non-exhaustive manner: the box 4 which is provided with at least one pair of horns 5; a near-field communication module 7 of the NFC type (acronym for “Near Field Communication”); a watch movement 6 such as an electronic movement comprising a microcontroller 8 configured to exchange electrical signals with the near-field communication module 7; a regulating device such as a quartz oscillator making it possible to supply a time base to the microcontroller 8 and also to actuate a stepper motor, or even several, rotating the time display hands and the elements of analog display of a mechanism of the horological function of the watch 2 such as the perpetual calendar; a strap mounted on the case 4; an analog and/or digital display therefore comprising hands, in particular three display hands respectively for the hour, the minute and the second; a mechanism for implementing the horological function such as a perpetual calendar mechanism; an input interface such as a touch screen or even push buttons, a crown, etc. a supply unit such as a cell or a battery/an accumulator making it possible to supply energy to the watch movement 6 and in particular the microcontroller 8 connected to the communication module 7. In FIG. 1, the case 4 comprises a caseband 14 which can be made of metal (eg steel, preferably stainless steel), a synthetic material (eg a composite material comprising a polymer matrix filled with fibers, typically carbon) or ceramic. The case 4 also comprises a back and a crystal which participate in forming with the middle part 14, an enclosure of this case 4. Such an enclosure is configured to accommodate in particular the watch movement 6 comprising the microcontroller 8 and the communication module 7 in field close. In FIG. 1, this middle part 14 comprises two pairs of lugs 5 on which a bracelet is intended to hang for wearing the watch 2 on the wrist.

[0015] Such a bracelet is preferably made of at least one dielectric and/or electrically non-conductive material such as for example a synthetic material (for example a composite material comprising a polymer matrix loaded with fibers, typically carbon) or ceramic or still plastic such as high performance plastic. It will be noted that when the bracelet is formed of links, the links which are directly fixed to the pairs of lugs 5 are made of at least one dielectric and/or electrically non-conductive material, the other links possibly being made of other various materials and varied. In this embodiment, the pairs of lugs 5 are connected to an elastomer strap that matches the shape of the middle part 14 to completely hide an outer face 21b of a support element 15 of the communication module 7 which we describe by the after.

The caseband 14 also comprises a through opening 23 arranged between the horns of one of the two pairs of horns 5. This opening 23 is therefore located in the between-horn 25 defined in the pair of horns 5 located at the level of the 6 o'clock of watch 2, but it can also be positioned in between the lugs 25 of the pair of lugs 5 located at 12 o'clock. This opening 23 is configured to be traversed by all or part of a body of a support element 15 of the communication module 7. has a general symmetry of revolution around a central axis A of the box 4.

In the present embodiment in which the horological function taken as an example relates to the perpetual calendar, it will then be understood that the mechanism which implements it comprises a set of elements, including the date display elements , day and month. The display elements are preferably analog display elements and comprise for example two hands to indicate the day and the month, and a disc to indicate the date. It is therefore understood that these display elements make it possible to indicate the date (date), the day, the month, and possibly the moon phase, automatically taking into account the different lengths of months and leap years. More specifically, a display element such as a hand makes it possible to point to a date, day, month or moon phase indication inscribed on the dial of the watch 2, or even a display element such as a disc on which date, day, month or moon phase indications are inscribed, one of these indications facing an aperture of the dial.

In the watch movement 6, the microcontroller 8 of this watch 2 is capable of controlling the mechanism implementing the watch function, in particular the means for positioning the elements of the perpetual calendar mechanism, in particular the display elements. The means for positioning the elements of the perpetual calendar mechanism advantageously comprise one or more stepper motors. The microcontroller 8 is also connected to control means, or input interface, which can be a crown, pushers or touch pads, operable directly by the wearer of the watch 2.

In the case 4 of this watch 2, the near-field communication module 7 is connected to the movement 6 by being arranged between the horns of said at least one pair of horns 5. Such a communication module 7 allows said shows 2 to be able to carry out two-way communication with the portable or mobile electronic device 3.

More specifically, this communication module 7 is linked to the microcontroller 8 of this movement 6. In this configuration, the near-field communication module 7 is linked/removably connected to the microcontroller 8.

Such a near-field communication module 7 implements, for example, short-range and high-frequency wireless communication technologies of the NFC type (acronym for "Near Field Communication" in English meaning "near field communication". “). This communication module 7 operates according to technologies which are different from RFID and Bluetooth. This communication module 7 can for example operate in the frequency bands relating to high HF frequencies, for example at 13.56 MHz.

The communication module 7 thus allows the realization of data exchange 13 at short distances between the watch 2 and the electronic device 3. Such distances can be between approximately 0 and 10 cm, and preferably between 0 and 5 cm. The communication module 7 of the watch 2 can be of the passive type with energy supplied to it by the radio frequencies emitted by the communication device 12 of the electronic device 3. Alternatively, the communication module 7 of the watch 2 can be of the active type with power supplied to it by the power unit of watch 2.

More specifically and with reference to Figure 2, the near-field communication module 7 comprises an electronic chip 17, at least one antenna 18 and a connector 19 for connecting said module 7 to the microcontroller 8. The chip 17 which is connected to said at least one antenna 18, comprises hardware and software elements. In this context, the hardware and/or software elements of chip 17 include at least one microprocessor cooperating with memory elements. The communication module 7 also comprises a substrate 16 which is advantageously made in the form of a printed circuit. Such a substrate 16 also called "support" or "plate" is preferably made of high performance plastic or laminated composites. This plastic material can be a polymer such as polyimide known as Kapton™ or even a polyester. The chip 17 and said at least one antenna 18 as well as the connector 19 are fixed for example by gluing on this substrate 16.

In this communication module 7, the substrate 16 is fixed on an inner face 21a of the support element 15 mentioned above. In other words, this support element 15 comprises the substrate 16 and of course all the other components forming the communication module 7. This support element 15 has a shape essentially similar to that of the opening 23 included in the middle part 14 or strictly similar to that of this opening 23. Such an element 15 therefore comprises the internal face 21a and an external face 21b, these two faces 21a, 21b being connected by a peripheral wall 22. Such a peripheral wall 22 comprises a cavity extending over the entire the length of this wall 22 so as to participate in defining the outline of this support element 15. This wall 22 also comprises a sealing element 20 with the middle part 14 to prevent any ingress of liquid such as an O-ring which is arranged in said cavity. Thus, the support element 15 thus closes off this opening 23 of the middle part and can for this purpose also be called “shutter element”.

This support element 15 has a thickness e which corresponds to the height or the width of this peripheral wall 22. This thickness e is substantially similar or strictly similar to the thickness of the portion of the middle part 14 comprising said opening 23. In other words, the opening 23 comprises an internal wall delimiting/defining the shape of this opening 23 and whose thickness is substantially similar or strictly similar to the thickness e of the peripheral wall 22 of the support element 15 .

This support element 15 is preferably made of at least one dielectric and/or electrically non-conductive material. It may be a synthetic material (eg in a composite material comprising a polymer matrix loaded with fibers, typically carbon) or ceramic or plastic such as high performance plastic. It will be noted that the outer face 21b of this support element 15 can be of the same color as the outer face 24 of the middle part 14 and can also have a texture substantially similar or strictly similar to this outer face 24.

[0027] In addition, it will be noted that the arrangement described here of the communication module 7 between the two horns of a pair of horns 5 of the watch 2, contributes to improving the quality of the bidirectional communication signal in the near field likely to be received or sent by this module 7.

In addition, in one embodiment, the communication module 7 of the watch 2 may comprise a magnetic shielding element (not shown) between the chip 17 and said at least one antenna 18 of this module 7, and the movement 6 of the watch 2. This magnetic shielding element makes it possible to improve the efficiency and the sensitivity of the reception/transmission of radio signals by the antenna 18 of the communication module 7 by isolating this antenna 18 from the metal components of the shows 2 included in its immediate environment. In other words, this magnetic shielding element makes it possible to avoid a modification of the magnetic field emitted or received by the communication module 7, which modification would be due to the presence of various metallic components of the watch 2 located in the immediate environment of the module communication module 7. In addition, it is able to reduce the negative influence that these metal components may have on the performance of the communication module 7. This negative influence would consist of the attenuation of the magnetic field generated or received by this communication module. communications 7.

In the adjustment system 1 shown in Figure 5, the portable electronic device 3 also called user terminal, is a device capable of being worn and transported by a user. This is the case, for example, of a smartphone, a phablet or even a tablet. Naturally, devices requiring mains power, for example desktop computers, are excluded from this definition. Devices such as, for example, a laptop computer to which a sensor is connected by wireless or wired link, are also excluded from this definition. This electronic device 3 is used to transmit the adjustment parameters to the watch 2. This electronic device 3 comprises a box 9 in which an electronic circuit 10 is arranged. This electronic circuit 10 comprises a microcontroller 11 and a near-field communication device 12, both powered by a battery. The electronic device 3 can also include a camera and an input interface such as a touch screen or even buttons. Furthermore, the microcontroller 11 can comprise in its memory elements an optical recognition algorithm to participate in the detection of information included in particular in the dial of the watch 2 from a processing of data coming from the camera. It will be noted that the communication device 12 of this device 3 is configured to connect and exchange 13 data with the near-field communication module 7 of the watch 2.

[0030] Referring to Figure 6, the invention also relates to a method for performing the adjustment of the watch 2. Such a method is implemented by the adjustment system 1 comprising in particular the electronic device 3 and the watch 2. It makes it possible to adjust at least one function of the watch 2 such as a horological function carried out by a mechanism for implementing such a function of this watch 2 such as for example the perpetual calendar mechanism. This perpetual calendar mechanism makes it possible, among other things, to achieve positioning of the display elements that compose it. Moreover, when the context relates to the adjustment of this perpetual calendar mechanism, it is possible to speak of a method for adjusting a perpetual calendar mechanism of the quartz watch 2.

This method comprises a step 30 of establishing a near field connection between the electronic device 3 and the watch 2. By "near field" it should be understood here that the connection is made using NFC technology ( acronym for "Near Field Communication", for near field communication) and insofar as the distance which separates the electronic device 3 and the watch 2 is between 0 and 10 cm, preferably between 0 and 5 cm.

Subsequently, this connection establishment step 30 comprises a sub-step 31 of initiation, in particular automatic, of a connection between the watch 2 and the electronic device 3 as soon as this watch 2 is located relative to the electronic device 3 at a distance allowing the establishment of a near field connection. In other words, such a sub-step 31 can be initiated manually or automatically.

[0033] When this sub-step 31 is performed manually, we then speak of a manual initiation sub-step 32a of a connection between the watch 2 and the electronic device 3 as soon as this watch 2 is located relatively to the electronic device 3 at a distance allowing the establishment of a near field connection. In this context, the watch 2 and the electronic device 3 are arranged relative to each other at a distance allowing the establishment of a near field connection. Subsequently, the communication module 7 of the watch 2 initiates a connection process with the communication device 12 of the electronic device 3, or it is the communication device 12 of the electronic device 3 which initiates this connection process with the communication module 7 of the watch 2 and this, following an interaction, as the case may be, between the user and an input interface of the watch 2, or the user and an interface of seizure of the electronic device 3.

[0034] When this sub-step 31 is performed automatically, the mere location of the watch 2 relative to the electronic device 3 at a distance authorizing the establishment of a near-field connection is sufficient to initiate the connection process between communication module 7 of the watch 2 and the communication device 12 of the electronic device 3. In this context, we then speak of a sub-step 32b of automatic initiation of a connection between the watch 2 and the electronic device 3 when this watch 2 is located relative to the electronic device 3 at a distance allowing the establishment of a connection. In this configuration, this sub-step 32b therefore participates in making an automatic connection, without user intervention on the watch 2 or the electronic device 3, between this watch 2 and the electronic device 3 as well as in a setting automatic watch functions of this watch 2 transparently for this user of said watch 2. It will be noted that this sub-step 32b can include an authentication phase between the module and the communication device 12 which is transparent for the user . In other words, such an authentication phase does not require the intervention of this user. In this context, authentication elements are included in the memory elements of the module and of the communication device 12.

[0035] Once the connection has been established between the watch 2 and the electronic device 3, the method comprises a verification step 33 by the microcontroller 11 of the electronic device 3 of the accuracy of a watch status datum of the watch 2. Such watchmaking state data is data making it possible to represent an at least partial state of adjustment of the watch 2. It may be for example a time zone, a country code, a an alarm, a geolocation, a date, a tide, a sun and/or moon phase, a UTC time, etc., set on the watch 2 In the case where the method aims to adjust said perpetual calendar mechanism, the status datum may relate to the current date, day, month or year (or even to the current moon phase when the perpetual calendar mechanism includes a moon phase display element, for example data relating to geolocation, hemisphere, country code, etc.), said data State e representing a current state of adjustment of the perpetual calendar mechanism, for example a position of a display element of said mechanism.

Such a verification step 33 comprises a transmission sub-step 34 to the communication module 7 of the watch 2 by the near-field communication device 12 and on command from the microcontroller 11 of the electronic device 3 controlling said device. communication 12 of an instruction for retrieving the watch state data of the watch 2. During this sub-step 34, a signal relating to said instruction is then generated by the microcontroller 11 to be transmitted to this communication device 12. Subsequently the communication device 12 then transmits this instruction to the communication module 7 of the watch 2.

Next, the verification step 33 comprises, following the receipt of this instruction by the watch 2, a sub-step of sending 35 to the electronic device 3 by the near-field communication module 7 on control of the microcontroller 8 of the watch 2, of the watchmaking state datum characterizing a current setting of the watch 2 corresponding to current setting parameters of this watch 2. During this sub-step 35, the microcontroller 8 determines the datum watchmaking status characterizing a current adjustment of a mechanism relating to a watchmaking function such as the perpetual calendar. In the context of the perpetual calendar, the status datum relates to the current date, day, month and year (and possibly to the current moon phase when the perpetual calendar mechanism includes an element of display of the moon phase, for example data relating to a geolocation, a hemisphere, a country code, etc.). This state datum is sufficient to represent a current state of adjustment of the perpetual calendar mechanism, in particular the position of the display elements of said mechanism. Subsequently, the microcontroller 8 then generates a signal comprising this watch status data item which is transmitted to the communication module 7. Subsequently, the communication module 7 of the watch 2 thus sends said status data item to the communications 12.

In an alternative to these transmission 34 and sending 35 sub-steps, the verification step 33 can provide a sub-step 36 for determining the watch status data from a reading process of a dial of the watch 2 performed by the electronic device 3 comprising the camera and of an optical recognition algorithm executed by the microcontroller 11 of the electronic device 3. Such a sub-step 36 then comprises a phase aimed at place the dial of the watch 2 and the camera of the electronic device 3 facing each other. By „facing each other“, we mean that the dial and the camera are positioned relative to each other and at a distance such that the time display hands are in the shooting range. view of the camera. Subsequently, this sub-step 36 comprises a phase of detecting information characterizing a current setting of the watch 2 which is included in the dial of this watch 2 and this, by means of the camera and the optical recognition algorithm of the electronic device 3. Next, this sub-step 36 comprises a phase of estimating the clock status datum from the information detected. This status datum can here also characterize a current adjustment of the perpetual calendar mechanism.

Subsequently, the verification step 33 includes a sub-step 37 of comparing the status data with adjustment parameters, in order to verify that the adjustment of the perpetual calendar mechanism is correct. These adjustment parameters are for example retrieved regularly or on request via an Internet network from the electronic device 3. By "adjustment parameter" is meant any parameter making it possible to at least partially adjust the watch 2. It may be for example information on a date as we have seen, but also information that may relate to a time zone, a country code, an alarm, a geolocation, a date, a tide, a sun phase and /or of the moon, a UTC time, etc. It should be noted that when it comes to setting parameters for the perpetual calendar mechanism, we then hear information relating to the date, day, month and time. current year (and possibly the current moon phase when the perpetual calendar mechanism includes a moon phase display element, this data then being for example a geolocation, a hemisphere, a country code, etc. ), this information being sufficient to correctly set t the perpetual calendar mechanism of watch 2, in particular the position of the display elements of this mechanism.

The method then comprises a step 38 of sending at least one adjustment instruction to the communication module 7 in the near field of the watch 2. This adjustment instruction is sent by the communication device 12 in the near field and on command from the microcontroller 11 of the electronic device 3 and this, as soon as the watchmaking status datum is identified/estimated as being inaccurate. During this step 38, a control signal relating to said adjustment instruction is generated by the microcontroller 11 and then transmitted to the communication device 12 of the electronic device 3. This control signal is such that it corresponds to a coding adjustment parameters of the perpetual calendar mechanism, i.e. coding of a set of data relating to the current date, day, month and year (and also to the moon phase, if applicable) . As we have previously specified, such adjustment parameters are for example retrieved regularly or on request via an Internet network from the electronic device 3. It is noted that to carry out the coding, it is advantageous to use a dedicated application installed on the electronic device 3. If the electronic device 3 is a smartphone or a touch pad, this application is advantageously capable of generating the coding from the date, day, month, year and geolocation data given by the device electronic 3. Subsequently, this adjustment instruction is then transmitted by the communication device 12 to the communication module 7 of the watch 2.

The method then comprises a step 39 of processing said at least one instruction received by means of the microcontroller 8 of the watch 2, in order to generate adjustment parameters for the watch 2. During this step 39, the microcontroller 8 processes said instruction in order to obtain the current perpetual calendar.

Next, the method includes a step 40 of configuring the watch 2 on command from the microcontroller 8 of the watch 2, according to the adjustment parameters generated. This step 40 comprises a sub-step of actuating the means for positioning the elements of the perpetual calendar mechanism so as to place said elements in a position corresponding to the adjustment parameters obtained during the processing step 39.

It will be understood that various modifications and / or improvements and / or combinations obvious to those skilled in the art can be made to the embodiment of the invention set out above without departing from the scope of the invention defined by the claims. annexed. For example, the verification step 33 could not be performed, the user himself translating the position of the time display hands into usable data.

[0044] Furthermore, even if the description details the adjustment and verification of the adjustment of a perpetual calendar mechanism, other adjustments could alternatively be carried out, for example the adjustment of a time zone, of an hour, tides, etc. This set information is moreover not necessarily displayed at the level of the watch 2 in an analog manner (by hands or discs, in particular), but can be displayed in a digital manner on the dial: the configuration step 40 does not include therefore not necessarily activation of means for moving analog display elements.
