Definitions

  • the present invention relates to the technical field of electronic watches.
  • the invention relates more particularly to a method for adjusting an electronic watch.
  • So-called “connected” watches capable of communicating with an electronic device such as a smartphone, have established themselves in recent years in the watch industry.
  • the adjustment of such a watch can be 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 adjustment.
  • 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.
  • 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.
  • the object of the present invention is to overcome these drawbacks by proposing a method for adjusting a perpetual calendar mechanism of a quartz watch, which is simple and reliable and which does not require the incorporation of complex communication means into to implement and expensive.
  • the invention relates to a method for adjusting a quartz watch, according to claim 1.
  • Preferred embodiments are defined in claims 2-9.
  • Adjustment parameter is understood to mean any parameter making it possible to at least partially adjust the watch. It can be, for example, a information on a time zone, country code, alarm, geolocation, date, tide, sun or moon phase, UTC time, etc.
  • point light source is meant a light source whose size is negligible and which can be considered as a point.
  • a point light source is for example a light-emitting diode.
  • opposite it is meant that the point light source and the optical sensor are positioned relative to each other and at a distance such that the optical sensor can directly receive and capture the light signals emitted by the point light source.
  • portable electronic device an electronic device, also called a user terminal, capable of being worn and transported by a user, and of being functional during its transport. This is the case for example of a smartphone.
  • devices requiring mains power for example desktop computers, are excluded from this definition.
  • the electronic device is used to transmit the adjustment parameters to the watch.
  • the transmission is carried out by means of an optical modulation or coding, the modulation being created by the flashing of the point light source of the electronic device.
  • Said point light source has two states: on or off.
  • the optical sensor of the watch therefore receives a sequence of light pulses.
  • the watch's microcontroller is able to reconstitute the setting parameters. For example, a light pulse represents a bit with a value of '1' and an absence of a light pulse represents a bit with a value of '0'.
  • the adjustment parameters once reconstituted, then make it possible to correctly adjust the watch.
  • This method has the advantage of being able to be implemented mostly automatically, without the user having to perform any complex adjustment via crowns, push buttons or touch keys for example.
  • the method must be initiated, which can be done either manually by pressing a push button, or automatically, for example via a system on standby by default which wakes up on receipt of a certain light sequence.
  • This method also has the advantage of requiring very little equipment: a portable device of the smartphone type with an appropriate mobile application is sufficient to implement it.
  • the method does not require the use of dedicated hardware such as a sensor to be connected to a computer, nor bulky hardware. Any person (for example a watchmaker) having a smartphone having the appropriate application could implement the method.
  • this method has the advantage of not requiring the incorporation of communication antennas (expensive, cumbersome and sometimes incompatible with metal casings) on the watch or the electronic device, the optical communication system between the watch and the electronic device consisting only of a point light source of the light-emitting diode type and of an optical sensor of the phototransistor type.
  • the watch includes a perpetual calendar mechanism.
  • a perpetual calendar mechanism has as a regulating organ a quartz oscillator actuating one or more stepper motors rotating the time display hands and analog display elements of the perpetual calendar mechanism.
  • These display elements make it possible to indicate the calendar (date), the day, the month, and possibly the moon phase, automatically taking into account the different lengths of months and leap years.
  • a display element is for example a needle making it possible to point an indication of date, day, month or moon phase inscribed on the dial of the watch, or even a disc on which indications of date, day, month or moon phases are inscribed, one of these indications facing an aperture of the dial.
  • the method may aim to adjust said mechanism.
  • Adjustment parameters of the perpetual calendar mechanism means information relating to the current date, day, month and 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 adjust the perpetual calendar mechanism of the watch, in particular the position of the display elements of this mechanism.
  • the method according to the invention may comprise one or a technically possible combination of the following characteristics.
  • Time display hands means the hour, minute and second hands.
  • status datum is meant datum making it possible to represent an at least partial state of adjustment of the watch. It can be for example a time zone, a country code, an alarm, a geolocation, a date, a tide, a sun or moon phase, a UTC time, etc., set on the show.
  • 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 comprises a moon phase display element, for example data relating to geolocation, hemisphere, country code, etc.), said state data representing a current setting state of the perpetual calendar mechanism, for example a position of a display element of said mechanism.
  • the optical sensor of the watch is a phototransistor.
  • the electronic device is a smartphone.
  • the MT watch comprises a BT case, a CD dial and a back to close said BT case on either side, and a BC strap mounted on the BT case.
  • the MT watch has an analog display, so it includes three time display AG hands to indicate the hour, minute and second.
  • the MT watch also includes a perpetual calendar mechanism.
  • the perpetual calendar mechanism comprises a set of elements, including EA date, day and month display elements (among the elements of the perpetual calendar mechanism, only the EA display elements are shown in the figures ).
  • the display elements EA are in this case two hands to indicate the day and the month, and a disc to indicate the date.
  • the perpetual calendar mechanism also comprises a moon phase display element, for example in the form of a representation of the moon able to move in a portion of the dial.
  • the BT case there is a microcontroller MP, a power supply unit PL such as a cell or a battery to power the microcontroller MP, and a quartz QX to provide a time base to the MP microcontroller.
  • the microcontroller MP is used to control positioning means DE of the elements of the perpetual calendar mechanism, in particular display elements EA.
  • the positioning means DE of the elements of the perpetual calendar mechanism advantageously comprise one or more stepper motors.
  • the microcontroller MP is also connected to control means which may be a crown CR, push-pieces PS or touchpads, actuated directly by the wearer of the watch MT.
  • the watch MT includes an optical sensor PR positioned on the movement of the watch MT on the back side and itself also connected to the microcontroller MP.
  • the PR optical sensor of the MT watch is capable of detecting a sequence of light pulses and transforming this sequence into an electrical signal.
  • the optical sensor PR is for example a phototransistor or a photodiode.
  • the portable electronic device TM is for example a smartphone or a touchscreen tablet.
  • the electronic device TM comprises a box in which an electronic circuit is arranged.
  • This electronic circuit comprises a microcontroller and a point light source EP, both powered by a battery.
  • the point light source EP of the electronic device TM is capable of emitting a sequence of light pulses from an electrical signal.
  • the point light source EP of the electronic device TM is for example a light-emitting diode used moreover as a camera flash.
  • the invention relates to a PCD method allowing the adjustment of the perpetual calendar mechanism of the watch MT, in particular the positioning of the display elements EA of said mechanism.
  • the PCD method firstly comprises an adjustment phase RGL itself of the elements of the perpetual calendar mechanism, then in one embodiment, a verification phase VRF (or validation) that the current adjustment of the perpetual calendar mechanism is correct .
  • the RGL adjustment phase includes a first step RGL_FD consisting of removing the back of the BT case of the MT watch so as to uncover the optical sensor PR of the MT watch.
  • the bottom of the case of a quartz watch is generally removable in order to be able to change the power supply unit PL of the watch MT.
  • This first step is however not compulsory: in fact in certain embodiments, the optical sensor PR of the watch MT is not located on the movement on the back side.
  • the optical sensor PR can be located under the dial CD, the latter having an opening or a transparent portion or being made of a partially transparent material.
  • the optical sensor PR can be arranged at the level of the edge of the case BT of the watch MT or even on a transparent portion of the back of the watch MT.
  • a second adjustment step RGL_PO then consists in placing the optical sensor PR of the watch MT opposite the point light source EP of the electronic device TM.
  • opposite it is meant that the point light source EP and the optical sensor PR are positioned relative to each other and at a distance such that the optical sensor PR can directly receive and capture the light signals emitted by the point light source EP.
  • a third adjustment step RGL_SG consists in sending an electronic control signal from the microcontroller to the point light source EP of the electronic device TM.
  • the control signal is such that it corresponds to a coding of adjustment parameters of the perpetual calendar mechanism, that is to say a coding of a set of data relating to the current date, day, month and year ( and also to the moon phase, if applicable).
  • These adjustment parameters are for example retrieved regularly or on request via an Internet network from the electronic device TM.
  • a fourth adjustment step RGL_CL consists in turning on and off the point light source EP of the electronic device TM according to a sequence of light pulses corresponding to the control signal received.
  • the control signal is binary, so that it can be interpreted by the point light source EP as a succession of instructions to turn on or off. For example, a low state or "0" corresponds to an instruction to turn off or leave off the point light source EP, and a high state or "1" corresponds to an instruction to turn on or leave the point light source EP on, or vice versa.
  • the optical sensor PR of the watch MT picks up the sequence of light pulses emitted by the source point light EP of the electronic device TM and converts it into a binary electrical signal.
  • a fifth adjustment step RGL_SE consists in transmitting this electrical signal to the microcontroller of the watch MT, which then decodes it to reconstitute the perpetual calendar in progress.
  • a sixth adjustment step RGL_DO consists, on command from the microcontroller of the watch MT, in actuating the positioning means DE of the elements of the perpetual calendar mechanism so as to place said elements in a position corresponding to the adjustment parameters obtained by the decoding.
  • the watch MT includes a point light source PE connected to the microcontroller MP of the watch MT, while the electronic device TM includes an optical sensor RP connected to the microcontroller of the electronic device TM.
  • the RP optical sensor of the TM electronic device is capable of detecting a sequence of light pulses and transforming said sequence into an electrical signal.
  • the optical sensor RP is for example a phototransistor or a photodiode.
  • the point light source PE of the watch MT is capable of emitting a sequence of light pulses from an electrical signal.
  • the point light source PE of the watch MT is for example a light-emitting diode.
  • a first verification step VRF_PO then consists in placing the point light source PE of the watch MT opposite the optical sensor RP of the electronic device TM.
  • opposite it is meant that the point light source PE and the optical sensor RP are positioned relative to each other and at a distance such that the optical sensor RP can directly receive and capture the light signals emitted by the point light source PE.
  • the point light source PE of the watch MT is positioned on the movement of the watch MT on the back side, but in other embodiments, the point light source PE of the watch MT is located at another place.
  • the point light source PE of the watch MT can be located under the dial CD, the latter having an opening or a transparent portion or being made of a partially transparent material.
  • the point light source PE of the watch MT can be arranged at the edge of the case BT of the watch MT.
  • a second verification step VRF_SG consists of sending an electronic control signal from the microcontroller to the point light source PE of the watch MT.
  • the control signal is such that it corresponds to a coding of state data characteristic of the current adjustment of the perpetual calendar mechanism.
  • the status data relate to the current date, day, month and year (and possibly the current moon phase when the perpetual calendar mechanism includes a moon phase display element , for example data relating to a geolocation, a hemisphere, a country code, etc.). These state data are sufficient to represent a current state of adjustment of the perpetual calendar mechanism, in particular the position of the display elements of said mechanism.
  • a third verification step VRF_CL consists of turning on and off the point light source PE of the watch MT according to a sequence corresponding to the control signal received.
  • the coding is binary, so that it can be interpreted by the point light source PE as a succession of instructions to turn on or off. For example, a low state or "0" corresponds to an instruction to turn off or leave off the point light source PE, and a high state or "1" corresponds to an instruction to turn on or leave the point light source PE on, or vice versa.
  • the optical sensor RP of the electronic device TM picks up the sequence of light pulses emitted by the point light source PE of the watch MT and converts it into a binary electrical signal.
  • a fourth verification step VRF_SE consists in transmitting this electric signal to the microcontroller of the electronic device TM, which then decodes it to reconstitute the status data.
  • a fifth verification step VRF_CM consists in comparing the status data with the adjustment parameters, in order to verify that the adjustment of the perpetual calendar mechanism is correct.
  • the watch MT may or may not include a point light source PE and the electronic device TM may or may not include an optical sensor RP.
  • the electronic device TM must comprise a camera CM, a screen EC and an otic recognition software.
  • a first verification step CRF_DA then consists, on command from the microcontroller of the watch MT, in actuating the means of rotation DA of the time display hands AG, so as to place said hands AG in a position characteristic of a status datum of the current adjustment of the perpetual calendar mechanism.
  • two hands indicate the type of status data
  • the third hand indicates the value of this data.
  • the "date" type is for example identified by the hour hand pointing to 1 and the minute hand pointing to 2, and the position of the second hand indicates the value of the date .
  • a second verification step VRF_PS consists in placing the dial CD of the watch MT and the camera CM of the electronic device TM opposite one another.
  • opposite it is meant that the dial CD and the camera CM are positioned relative to each other and at a distance such that the time display hands are in the field camera shot.
  • a third verification step VRF_DT consists, by means of the camera CM and the optical recognition software, in detecting the position of the time display hands AG.
  • This step consists of taking a photograph of the time display hands AG, this photograph then being analyzed by the optical recognition software.
  • the software compares the position of the time display hands AG with fixed marks on the dial CD (for example the indexes of the watch) to determine the time indicated.
  • a fourth verification step VRF_CV consists in decoding the detected position of the time display hands, in order to reconstitute the coded status datum.
  • Steps 1 to 4 are then repeated for a different state data, until all the state data necessary to determine whether the perpetual calendar mechanism is correctly adjusted, have been transmitted from the watch MT to the TM electronic device.
  • a fifth verification step VRF_SP consists in superimposing the dial displayed on the screen of the electronic device TM (the dial being filmed or photographed via the camera, for example), one or more virtual objects representative of the state data obtained by the decoding, according to the principle of augmented reality. For example, if the “date” status datum has been transmitted and decoded, a virtual object illustrating the date is superimposed on the dial.
  • VRF verification phase is optional. It should also be noted that the VRF verification phase can be carried out at any time: thus a user can at any time ask the watch MT to adjust the date, day and month and display this information on the electronic device TM (for example a smartphone). No communication system is necessary between the watch MT and the electronic device TM to provide this verification information. Finally, it is noted that the electronic device used in the verification phase VRF could very well be distinct from the electronic device TM used in the adjustment phase RGL.
  • steps 2 to 5 could not be carried out, the user himself translating the position of the time display hands into usable data.
  • this adjusted information is not necessarily displayed at the level of the watch in an analog manner (by hands or disks, in particular), but can be displayed in a digital manner on the dial: the adjustment step therefore does not include necessarily activation means for moving analog display elements.
