Description

[Technical field]

[0001] The present invention relates to a method for determining at least one item of morphological data relating to a wrist strap wearer and to a method for configuring a watch wrist strap, in particular its length. The present invention also relates to a system for determining at least one item of morphological data relating to a wrist strap wearer and to a system for configuring a wrist strap implementing part of the method. [Background technology]

[0002] One of the key operations for the comfort of the wearer of a watch is to select the best configuration of the wrist strap, and in particular to achieve the best adjustment of the wrist strap length. Of course, the first step is usually to add or remove extension linkages or links to adjust each strand to bring the wrist strap to the optimal length. The results obtained are generally not optimal. For this reason, various wrist straps are offered, in particular with deployment clasps, with some additional adjustment devices.

[0003] Specifically, in wrist straps fitted with a deployment clasp, the clasp is generally provided with a first adjustment device for positioning relative to the wrist strap, which is a prior art adjustment device. In addition, existing deployment clasps are provided with solutions that allow a second adjustment to be made to the length of the wrist strap, known as a comfort adjustment device, which complements the prior art first adjustment device. US Pat. No. 5,399,433 discloses, for example, a solution that relies on an adjustment linkage arranged in the deployment clasp and which can be pivoted to occupy two stable positions resulting in two different strap lengths. The short position is maintained by a catch on the end linkage of the wrist strap, in which the wrist strap is elastically immobilized by the catch hooking against the adjustment linkage. For this reason, such a solution requires several linkage articulations and linkage hooking to ensure the stability of the short position.

[0004] Finally, solutions exist for achieving fine adjustment of the length of the wrist strap. In practice, the circumference of the wrist of the individual who will wear the wrist strap is measured using a calibrated tape, the wrist strap is then prepared based on this data, and various adjustments are made that may require many iterations until the theoretically ideal or optimal strap configuration is achieved. Achieving this often relies on the experience of the operator, which may prove to be imprecise and time consuming.

[0005] Furthermore, other data may have to be taken into account when configuring the wrist strap, especially if the strap is provided with a clasp, in particular a deployment clasp. The deployment clasp is designed to fasten the two strands of the small watch strap around the wrist of its wearer and may include several articulated leaves that can take a closed first position, which requires a fastening function to stabilize the closed position, and a released second position, which allows the small watch strap to be attached to and removed from the wrist. The advantage of such a clasp is that the wrist strap strands remain permanently connected, thus preventing the watch from falling off when removed. However, the overall dimensions of the wrist strap when deployed, in the open position of the deployment clasp, must allow it to be attached beyond the hand. In such cases, it is advantageous to take into account not only the wrist clearance, but also the circumference of the hand as the "hand clearance", as described below.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] For ease of explanation, and by convention, the term "longitudinal" is used to refer to a direction along the length of a wrist strap strand or deployment clasp, and the term "transverse" is used to refer to a direction perpendicular to the plane of the wrist strap strand, i.e. across the width of the wrist strap strand or clasp. The vertical direction is perpendicular to the first two directions, that is, perpendicular to the plane of the wrist strap strand. Furthermore, the term "link" is used to refer to an individual element of the wrist strap, and "linkage" is used to refer to a collection of links. "Wrist strap" refers to either the entire wrist strap, with or without a clasp, or one or the other of the strands of the wrist strap. Furthermore, the same reference numbers are used to refer to elements that are the same or similar, or have the same function, in the various embodiments.

[0032] The present invention is based on a method of determining at least one item of morphological data relating to a wrist strap wearer, which forms part of a method of configuring a wrist strap, one embodiment of which comprises the steps and operations illustrated diagrammatically in FIG.

[0033] The method for configuring a wrist strap comprises a first step E1 of obtaining at least one item of morphological data relating to a wearer of said wrist strap, which forms a method for determining at least one item of morphological data relating to a wearer of said wrist strap according to an embodiment of the present invention. This method comprises, inter alia, a first step E1 of at least partly automatically obtaining at least one item of morphological data relating to a wearer of said wrist strap.

[0034] This morphological data item may comprise a first wrist dimension 1, which may in particular correspond to the circumference of the wearer's wrist, which is intended to receive the watch. By "wrist circumference" is meant the circumference of a wrist portion p1, which may receive the watch, as shown in FIG. 2. This first dimension may alternatively or additionally relate to the height and / or width of said wrist portion p1. In an advantageous variant embodiment, at least a second morphological data item may be acquired about the wearer. The second data item may correspond to a second dimension 2, which may in particular correspond to the hand clearance of the wearer, useful in the case of wrist straps with a deployment clasp. Here, "hand clearance" means the maximum circumferential area of ​​the area of ​​the hand portion p2, as shown in FIG. 2, through which the wrist strap with the deployment clasp in the deployed open position can pass. To this end, the second dimension 2 may comprise the circumference and / or the height and / or the width of said hand portion p2. Alternatively, other morphological data may be acquired and used.

[0035] According to one embodiment, the first step E1 of acquiring at least one morphological data item uses, in a first operation O11 of the first acquisition step E1, a digital determination system 11 belonging to an equipment 110 of the wrist strap configuration system, which is able to automatically acquire at least one morphological feature. By "morphological feature" is meant a digital data item or a group of digital data items from which at least one morphological data item can be obtained, possibly after processing.

[0036] The determination system 11 comprises, for example, a camera, making it possible to obtain a video or one or more images of the morphology in the region of the wearer's wrist and possibly in the region of the hand according to the described advantageous embodiment. More generally, in an advantageous variant embodiment, the determination system 11 may take the form of an imaging system provided with at least one sensor, for example a lens, intended to scan, image or photograph at least the wearer's wrist portion p1 in order to obtain and / or reconstruct at least one image of the portion p1. The imaging system according to the advantageous embodiment may also be configured to scan, image or photograph at least the wearer's hand portion p2 in order to obtain and / or reconstruct at least one image of the portion p2. Also more generally, the determination system 11 is a system set up to receive and possibly emit waves in order to obtain at least one characteristic of the wearer's wrist portion p1 and preferably of the hand portion p2. Thus, according to an alternative variant embodiment of the determination system 11, the determination system may comprise, for example, a device provided with at least a laser, making it possible to obtain a constellation or a cloud of points forming a part of a constellation of the wearer's wrist portion p1 and preferably of the hand portion p2.

[0037] According to this embodiment, the first operation O11 firstly enables the determination system 11 to determine the part or parts p1, p2 to be considered. For this purpose, a first variant comprises using a man-machine interface to transmit a numerical representation of at least one wrist part p1 and / or hand part p2 to be considered, which corresponds to a digital model of the end of the wearer's arm, said model being obtained during the first acquisition step. As a variant, an indicator is placed on the wearer's wrist and / or hand before or during the digital acquisition by the operator in order to indicate the at least one part to be considered. The determination system can thus obtain a digital model of the end of the wearer's arm, on which the part or parts to be considered are identified and known. According to another variant, the determination system uses a computer to automatically determine on the obtained digital model at least one wrist part p1 and / or hand part p2 to be considered, for example by measuring the distance from at least a part, such as the end of the hand, identified on said digital model, for example the end of the middle finger or the wrist joint.

[0038] At the end of the first operation O11, the method performs a second operation O12 of the acquisition step E1, which determines at least one morphological data item from the morphological feature or features obtained during the first operation O11. In particular, according to the above-mentioned embodiment, said second operation O12 makes it possible to determine with precision the circumference and / or height and / or width of the wrist part p1 and the circumference and / or height and / or width of the hand part p2. For this purpose, the feature or features derived from the first operation O11 are processed, preferably using software means belonging to the determination system or to another computer, for example a central processing unit, of the configuration system, in order to deduce the dimensions 1, 2 forming the morphological data item sought. For ease of explanation, these dimensions 1, 2 are hereinafter likened to morphological data items 1, 2.

[0039] According to an embodiment of the invention, the morphological features may be two-dimensional or three-dimensional images of the wearer's wrist part p1 and hand part p2. More generally, these morphological features form a digital model of the wearer's wrist or hand part, or digital data relating to the positioning, advantageously three-dimensional positioning, of several points of the wrist part or hand part. From these features, software means can calculate the desired morphological data item. This calculation is for example done using image processing. If the features contain enough images to visualize the entire contour to be measured to obtain the circumference, the calculation consists in adding up the lengths of the various parts of this contour obtained separately to reconstruct the desired morphological data item. If the images are not sufficient to characterize the entire contour, the missing parts are calculated by extrapolation. For this purpose, geometric calculations are used. In a variant, an image or a number of images are sufficient to obtain the height and / or width of the wrist part p1 and / or hand part p2. In addition, these results can also use parameters obtained by learning. The same principle applies if the features are points on the contour to be measured. At the end of the second operation O12, the configuration method can automatically and reliably and instantly build the configuration data necessary to correctly configure the wrist strap.

[0040] Of course, the morphological data mentioned in this embodiment are cited as an advantageous example, other embodiments can be conceived using only one of these data items, which may or may not be combined with the single or multiple morphological data items of the above-mentioned embodiment, or at least one other morphological data item.

[0041] Furthermore, in addition to the morphological data, other preference data useful for configuring the wrist strap may be transmitted to the wrist strap configuration system. These data may include, among other things, the wearer's preferences, particularly with regard to wearing the wrist strap. The watch wearer preference data may, for example, include first preference data 3 relating to a desired strap type or multiple strap types, e.g., metal wrist straps or flexible wrist straps, wrist straps with or without deployment clasps, among other things, within the range offered in the catalogue of watches offered by the manufacturer.

[0042] These preference data may also include one or more second preference data items 4 relating to how the wearer wants the wrist strap to go around his wrist, i.e. defining how much or little slack (play) should exist between the wrist and the wrist strap, and possibly relating to the wearer's lifestyle, in particular the weather conditions where the wearer lives, and / or at least one activity in which the wearer may participate, such as a sport, which is likely to change the wrist dimension 1. The second preference data items 4 may in particular include a dimension 1' derived from the dimension 1 relating to the wrist, which dimension 1' may be adapted to adapt said dimension 1 relating to the wrist portion p1 to a particular situation different from the situation of the operation O11, for example after some activity, such as participation in a sport. Said dimension 1' may for example be obtained through a predictive analysis, based on the morphology data 1, 2 and possibly the second preference data 4. In a variant, the derived dimension 1' may be obtained by referring to a database prepared in advance, in particular based on a survey carried out independently by the manufacturer.

[0043] The wrist strap configuration method according to an embodiment of the invention then advantageously, but optionally, performs the intermediate step E2 of determining at least one optimum configuration of the wrist strap suited to the wearer, one embodiment of which is described below with reference to Figure 4. Said step is advantageously performed fully or partly automatically, as described below, although in a variant said step may be manual.

[0044] In a first operation O21 of said decision intermediate step E2, the morphological data item or items 1, 2 from the first step E1, in particular the wrist and hand dimensions, are transmitted to a calculation unit of the wrist strap configuration system and processed by a computer program of the computer designed to provide an optimal strap configuration c*. In a manual variant, the salesperson can also look up the optimal configuration on a pre-prepared chart.

[0045] According to an embodiment, the wearer preference data 3, 4 is also transmitted to a computation unit of the wrist strap configuration system to be taken into account.

[0046] A second operation O22 of the determination intermediate step E2 comprises the determination of a small watch circumference (TDM) corresponding to the overall shape of the wrist strap in the closed position, attached to the small watch case and worn around a specific shape F that adopts a wearer's wrist portion p1, as shown in Figure 3. The small watch circumference (TDM) corresponds or maximally corresponds to the circumference of the wearer's wrist portion p1 and / or to the height and / or width of the wrist portion p1.

[0047] For this purpose, the specific shape F is advantageously set up so as to correspond maximally to the wrist portion p1 which may receive the watch 13 and which is known from the morphological data item or items 1. For example, the specific shape F may be an ellipse. The coefficients defining the ellipse are adapted so as to correspond maximally to the wrist height and / or width, if said data form part of the known morphological data. In a variant, other oval shapes may be chosen, for example shapes closer to a rectangle.

[0048] The miniature watch circumference obtained by the above considerations may optionally be adapted using weighting factors to enable the watch to be worn on the wrist portion p1 with an optimal amount of slack for the wearer's comfort. The weighting factor thus corresponds to the amount of slack considered optimal. It may be a predetermined constant or may be adjusted to take into account the specific shape of the wearer's wrist portion p1. For example, the weighting factor may be increased if there is a greater difference between the specific shape F and the shape of the wrist portion p1. These calculations may be performed automatically by the computer of the central processing unit of the configuration system from digital data stored in the associated electronic memory.

[0049] Then, according to an embodiment of the present invention, the watch circumference obtained above from the morphology data alone is adapted again to take into account the wearer preference data. The watch circumference obtained above may trigger the determination of a desired watch circumference (TDMS).

[0050] In particular, the preference data may include information on whether the watch is worn tightly or loosely. Depending on the wearer's situation, the watch circumference is modified by applying a second weighting factor that can increase or decrease the amount of slack around the wrist. In addition, the preference data may relate to the place where the wearer resides or the activity he or she participates in, which is taken into account by applying other weighting factors or by parameters in the configuration of the watch that allow an adjustment to adapt to the specific activity being performed. In the latter case, the watch can be adapted by adjusting a first optimal configuration of the wrist strap to a different second configuration that is optimal for the specific activity.

[0051] In a third operation O23 of the decision intermediate step E2, based on the previously established watch circumference (TDM) or desired watch circumference (TDMS), the actual configuration of the wrist strap is finally determined. This operation O23 seeks one or more wrist strap configurations that correspond to or maximally satisfy the watch circumference considered. For this purpose, this operation O23 involves iterating through a wrist strap database, in particular a wrist strap configuration data database that includes data on all or most of the existing configurations of wrist straps of a given watch according to the first preference data 3, in order to find an optimal configuration c* of the wrist strap that is best suited to the watch circumference considered. This optimal configuration is selected in particular from among the configurations that allow the watch case and / or clasp to be best centered or even on the wearer's wrist portion p1. Furthermore, the program additionally verifies that, in case of the presence of a deployment clasp, the applied wrist strap configuration is compatible with the hand portion p2 when the deployment clasp is in the open position. In this way, the method automatically defines the optimum compromise between the watch adequately and comfortably covering the wearer's wrist, whatever the dimensions of the wearer's hand and wrist, and its ability to provide a sufficient opening to allow the wearer's hand to pass through.

[0052] It is noted that said operation O23 may be repeated depending on the first preference data 3, in particular depending on the different types of desired wrist straps when there are several of them. Thus, for each type of wrist strap compatible with the small watch case selected by the wearer, the program may test the various possibilities each of them offers in order to establish an optimal configuration for each of them. Thus, at the end of the iterations, the program may optionally deliver a numerical indication to the morphology data item or items 1, 2 and possibly to the preference data item or items 3, 4 as the most suitable optimal configuration from among the various optimal configurations of the different wrist straps.

[0053] In other words, at the end of the iterations, the program will employ the optimal configuration for the wrist strap that provides optimal comfort for the wearer. The program may also employ the wrist strap or straps in the configuration best suited to provide optimal comfort for the wearer.

[0054] For each wrist strap type considered, the program proceeds by iterating through the various possibilities stored in the wrist strap database to test various possible configurations for each wrist strap and converge to an optimal configuration. Among the configuration options for a given type of wrist strap, the following are mentioned: - determining the clasp, assuming there is more than one clasp that is compatible with a given type of wrist strap; and / or - if the type of wrist strap consists of links or linkages, determine the number of links or linkages, and in particular the number of extension linkages or links, for each strand of the wrist strap; and / or - determining a configuration or configurations of at least one link or at least one link mechanism for at least one wrist strap strand, if the at least one link or at least one link mechanism is likely to have multiple configurations; and / or - determining the positioning of the linkages at the ends of the wrist strap strands relative to the selected wrist strap clasp and / or relative to the small watch case, in particular to obtain length adjustment; and / or - determining one or more wrist strap clasp configurations if multiple configurations are possible for the clasp under consideration; and / or - Providing a length adjustment or adjustments within the wrist strap clasp and / or at the connection with the small watch case.

[0055] Finally, if several types of wrist straps are substantially equivalent and have configurations that match the wearer's characteristics, these may be suggested to the wearer, who may then make the final selection of wrist strap type.

[0056] In a variant embodiment of said intermediate step E2 of decision, the computation unit of the wrist strap configuration system comprises a wrist strap database containing correlations between morphology data, and possibly preference data, and configurations of wrist strap types. Thus, from knowledge of the data derived from the first step of obtaining, the second operation O22 can directly consult the database for a suitable wrist strap configuration or configurations for each of the wrist strap types. In this variant, the program in the computer selects, for a given model of watch case selected by the wearer, the optimal watch strap configuration or configurations c* that best suits the wearer's morphology and possibly the wearer's preferences.

[0057] At the end of the decision intermediate step E2, the optimal watch-strap configuration or configurations c* that best suit the wearer's morphology and possibly the wearer's preferences are communicated to the watchmaker, to the retailer or to the manufacturer, etc., and / or to the wearer via the man-machine interface of the wrist strap configuration system. - a selected strand or strands, and / or - the selected clasp, and / or - Linkages or links that are added and / or removed from one or the other of the strands, and / or - the linkages or links to be arranged in a predetermined configuration, and / or - the linkages or links which are to be moved relative to the strand, in particular the clasp and / or relative to the watch case, and / or - length adjustment of the length adjustment linkages in the clasp and / or in the connection with the small watch case, This may include all details regarding adjustments and options for the type of wrist strap employed, including:

[0058] It is noted here that the intermediate decision step E2 may determine several optimal configurations for different types of wrist straps that may have equally optimal configurations, or for a single wrist strap, according to different specific usage scenarios.

[0059] The method of constructing a wrist strap then includes a second step E3 of preparing the wrist strap for the wearer in the optimal configuration determined in the previous step, whereby a watchmaker, or any individual qualified to perform the second preparation step E3, performs a final fitting and / or final adjustment of each wrist strap strand, based on the detailed information determined and communicated at the end of the previous step. As a result of said final step, the method of constructing a wrist strap according to the invention can also be considered as the final step in a method of manufacturing a wrist strap, or in a method of final fitting or adjustment of a wrist strap.

[0060] In accordance with one advantageous embodiment, the wrist strap configuration system, as shown in FIG. 5, includes a man-machine interface through which one or more images are communicated to aid in the final configuration of the wrist strap.

[0061] According to one embodiment, the selected wrist strap may be transported and stored in a pre-defined configuration, in which case this second step E3 consists of changing the wrist strap from the pre-defined configuration to the optimal configuration established in the decision intermediate step E2.

[0062] In said second step, the watchmaker, or any individual qualified to carry out said second step, can select in a first operation O30 at least one wrist strap strand 6 from among n strands of different lengths. Then at least one wrist strap length setting device 5 can be executed. This can be for example a means 51 allowing the attachment or removal of an extension linkage or link to the wrist strap strand, in order to achieve the best adjustment of the length of the strand, and more generally of the wrist strap, or other means 52, 53 making the links or linkage of the strand configurable in a predefined configuration, or allowing the configuration of the position of the strand relative to the clasp or to the small watch case.

[0063] In the special case of a metallic or partly metallic wrist strap provided with a linkage, the watchmaker may add or remove links or linkages 61 from the first strand 6 of the wrist strap and / or from the second strand 6' of the wrist strap in a second operation O31 shown in figure 6, using means allowing easy removal / reattachment, for example screws 7, in particular elastic screws. According to preference, said second operation O31 is carried out exclusively by the watchmaker.

[0064] In a third operation O32, shown in Fig. 7, the watchmaker may position an end of one strand 6 of the wrist strap relative to a cover 8 of a deployment clasp 80, for example by using a device 53 which holds a linkage 62 in position, for example via a system of notches 81. The system of notches may for example comprise a cover 8 provided with a system of indexing teeth 82 designed to cooperate with projections 63 of the strand 6. Such a device may be operated by the watchmaker as well as by the wearer of the watch. Alternatively or additionally, a link or linkage may be indexed relative to the cover of the clasp via a plurality of positionable bars of the cover (not shown).

[0065] In a fourth operation O33 shown in Fig. 9, the watchmaker may configure the extension linkage or link in a first or second configuration to lengthen or shorten the first and / or second wrist strap strand. For example, the adjustment linkage 64 is provided with two articulation axes A1, A2 connected to the cover 8 of the deployment clasp 80 and to the end link 65 of one strand 6 of the wrist strap, respectively. The connection linkage 64 is pivotable with respect to the first axis A1 connected to the cover 8 of the deployment clasp 80 to move the second axis A2 connected to the end link 65 to one side or the other of the first axis A1 to define two determined lengths of the wrist strap. The end link 65 connected to the adjustment linkage 64 includes a notch 66 that is elastically immobilizable with respect to the adjustment linkage 64 when the adjustment linkage 64 is in a position corresponding to the short configuration of the wrist strap. Fig. 8 illustrates the device when the wrist strap is in the short configuration, and Fig. 9 illustrates the device in the process of being actuated.

[0066] It is also possible to carry out a fifth operation O34 of selecting a deployment clasp 80 from n clasps of various sizes. For example, in the case of a deployment clasp provided with leaves 71, 72 as shown in FIG. 10, different sizes of leaves may be provided to best fit the morphology of the wearer of the small watch. Such a deployment clasp may comprise two leaves. Alternatively, the deployment clasp may comprise more than two leaves, for example three leaves, with the aim of obtaining a maximized deployment that allows the wearing or removal of the watch regardless of the size of the wearer's hand, in particular the position p2 of the wearer's hand. Additionally or alternatively, such a clasp may comprise at least one leaf having at least a portion that can have two predetermined configurations when the clasp is operated, in order to make it easier to pass the wearer's hand, in particular the position p2 of the wearer's hand.

[0067] Such an operation may be preceded by one or the other of operations O31, O32, O33.

[0068] Of course, all of these operations are arbitrary and not necessarily in any hierarchical order, so that to change from a given configuration of the watch to an optimal configuration c* of the wriststrap, the watchmaker may, for example, perform all or some of the operations O30, O31, O32, O33, O34 described above.

[0069] The method is not limited to the type of wrist strap with a metallic link mechanism. In the case of a flexible wrist strap, the strands of which are, for example, at least partially made of leather, elastomer or fabric, the first operation O30 of selecting at least one strand from n strands of different lengths is advantageously performed before any other operation. All or part of the operations O31, O32, O33, O34 may also be performed, but are not required. In particular, one end of the flexible strand may be placed in a predetermined position relative to a clasp, in particular relative to a cover of a deployment clasp. The flexible strand may be reduced to a single strand. Alternatively, the flexible strand may be connected to a deployment clasp via one or more metallic links. The clasp of the "flexible wrist strap" may potentially include a leaf and / or a cover. Alternatively, the clasp may be reduced to a buckle, in particular a buckle-barb (or more generally any non-deployment clasp). In the latter case, the preparatory second step E3 may be reduced to cooperating the barb with a means, such as a hole formed in the strand, identified during the decision intermediate step E2 and selected during the first operation O30.

[0070] The invention also relates to a wrist strap configuration system employing the above-mentioned configuration method, said wrist strap configuration system comprising at least one determination system 11 for determining at least one item of morphological data relating to the wearer of the wrist strap, in order to determine an optimal configuration of the wrist strap according to at least one item of morphological data acquired by the determination system 11, and possibly a computer of a calculation unit for carrying out the above-mentioned intermediate determination step E2.

[0071] The determination system 11 is configured to receive and possibly transmit waves so as to acquire at least one morphological characteristic of the wearer of the wrist strap. The determination system 11 is configured to execute a method for determining at least one morphological data item of the wearer of the wrist strap. Advantageously, the determination system 11 includes an acquisition device, such as at least one sensor, such as a camera, a laser or a lens, configured to scan, image or photograph at least a part of the wearer's wrist and / or hand. For example, this may be an infrared camera capable of acquiring and / or mapping points of the wearer's forearm by projection, which allows to create a model of the wearer's forearm. The determination system 11 may additionally include a computer configured to calculate at least one morphological data item from the at least one morphological characteristic acquired by the acquisition device using the above-mentioned method. Finally, the determination system 11 may include a man-machine interface, preferably configured to receive input of at least one data item related to the wearer of the wrist strap. The man-machine interface may also, in a variant, display a digital model of the wearer's forearm, or simply display the automatically determined parts, so that the wearer may possibly take action, for example participating in the determination of the wrist part p1 and the hand part p2. The determination system may be coupled to a central processing unit through a communication device.

[0072] The invention also relates to such a determination system itself, for example in the form of a portable object, comprising a computer arranged to carry out at least the first acquisition step E1 of the method described above.The invention also relates to a computer program comprising instructions which, when executed, cause the program to carry out at least said first acquisition step E1 of the method for determining at least one item of morphological data relating to the wearer of the wrist strap, i.e. of the method for configuring the wrist strap.

[0073] As a preference, the determination system and the central processing unit are located nearby or in the same equipment. They may share a single and common computer. In this way, the configuration system, or at least the determination system, forms an equipment 110, which advantageously takes the form of a small equipment device that is easily transportable and / or can be simply installed in a retail store. As a preference, said equipment 110 takes the form of a mobile phone or smartphone, a tablet or a pair of glasses that can be operated by a watchmaker or retailer and that accompanies the wearer of the watch through a particularly entertaining and not excessively time-consuming purchasing experience. Alternatively, the equipment is a tool belonging to the wearer, allowing a remote purchase away from the retail store, for example from home.

[0074] In a variant, the device 110 including the system 11 for determining at least one morphological data item relating to the wearer of the wrist strap takes the form of a portable equipment device, shown in Fig. 11, including at least a first part 111 of annular or substantially annular or elliptical or substantially elliptical shape. Said first part 111 more particularly includes an acquisition device, including several emitters / receivers 11a, for example laser beams. The first part 111 of the device 110 is intended to encompass a part p1 of the wrist and / or a part p2 of the hand, so as to automatically acquire at least one morphological characteristic of at least one of the two parts. As a preference, the device 110 includes a second part 112 in the form of a handle. Advantageously, said second part 112 of the device 110 can be handled by a watchmaker or any qualified person such that the first part 111 of the device 110 can surround part p1 of the wrist and / or part p2 of the hand of the wearer and can proceed to the execution of a method for determining at least one item of morphological data relating to the wearer of the wrist strap, in particular the above-mentioned acquisition step E1.

[0075] Advantageously, the second part 112 of the device 110 comprises a screen 112a designed to display at least dimension 1, in particular the circumference and / or height and / or width of the wearer's wrist part p1, and / or dimension 2, in particular the circumference and / or height and / or width of the wearer's hand part p2.

[0076] The equipment 110 advantageously enables the execution of a first acquisition step E1 as described above, including various sub-operations of a first operation O11 as follows: a first operation O111, consisting of applying power to the device 110, for example by pressing a key 112b of the part 112, - a second operation O112 consisting of slipping the first part 111 of the device 110 around the wrist or hand of the wearer and positioning the first part 111 against the part p1 or p2. Thus, according to an embodiment, a reflective colored line on the wrist or hand of the wearer can be used to indicate one or the other of the parts p1, p2; a third operation O113, consisting of checking the position of one or the other of the parts, for example by pressing a key 112c of the device 110, and in particular a key 112c of the second part 112 of the device 110, A fourth operation O114, consisting of checking the centering around the first part p1 or the second part p2 of the device 110. For this purpose, a visual and / or audible confirmation may be emitted from the device 110.

[0077] The first acquisition step E1 then comprises the execution by the same device 110 of the above-mentioned second operation O12, in which the device determines at least one item of morphological data from the morphological feature or features obtained during the first operation O11. In particular, said second operation O12 makes it possible to accurately determine the circumference and / or height and / or width of the wrist part p1 and / or the circumference and / or height and / or width of the hand part p2. To this end, the feature or features from the first operation O11 are processed, preferably by software means of the determination system, in order to determine the dimensions 1, 2 forming the morphological data sought. Said second operation O12 comprises, inter alia, a sub-operation O121 of displaying and reading out one or the other of the dimensions 1, 2 on the screen 112a of the second part 112 of the device 110. An intermediate operation of selecting a unit of measurement is also proposed, for example by pressing a key 112d on the device.

[0078] As an alternative to the portable device 110 shown in Figure 11, a similar device may take the form of a non-portable object, for example, an object placed on a table. The device may, for example, include a circular or substantially circular or elliptical or substantially elliptical portion 111, similar to the shape illustrated in Figure 11, connected to a strand designed to rest on a table. The various components and operation of such an equipment device would be very similar to those described above.

[0079] As mentioned above, the central processing device, which advantageously executes the intermediate determination step E2, is advantageously integrated in the same first equipment 110 used in the first acquisition step E1. Alternatively, it may be a separate entity, for example a desktop computer. In this case, the determination system is connected to said computer, preferably automatically, through a communication device for transmitting the data acquired and / or processed locally in the determination system. In the latter case, the first device 110 used in the first step E1 may be a device belonging to the wearer, such as a tablet or a smartphone, among others. The central processing device, which executes the second step E2, may be locally present in the retail store or may be a remote unit, for example housed by the manufacturer, which is connected through a communication device to at least one determination system.

[0080] Finally, the wrist strap configuration system includes one or more electronic memories, inter alia, to accommodate the databases mentioned in the description of the method. The electronic memory or memories are connected to a mid-tier processing unit through one or more communication devices. Such memories may be integrated in a compact device forming the configuration system, or alternatively may be remotely connected to a central processing unit or decision system through a communication device.

[0081] The method according to the invention has been described in the context of a scenario in which the wriststrap is configurable at the sale of a particular model of watch, but of course the method may also be performed after the sale or independent of the sale of the watch to inform the wearer of the watch of the optimal configuration c* of his or her wriststrap.

[0082] Alternatively, the present invention relates to a method of configuring a watch wrist strap for a given wearer, the method comprising: - a first step of obtaining at least one morphological data item 1, 2 relating to a wearer of the wrist strap; - an intermediate step of automatically determining at least one optimal configuration c* of the wrist strap suitable for the wearer from at least one morphological data item 1, 2 obtained in the preceding step, - A second step of preparing the wrist strap for the wearer in the optimal configuration determined in the previous step. The steps include:

[0083] In this alternative, the decision intermediate steps correspond to the automatically performed decision intermediate steps described above.

[0084] According to this alternative variant, the first acquisition step E1 of the method can be simplified. For example, the step can be carried out using a conventional system of tape measurement type. Such a tape can be returned or not by an elastic device. Alternatively, the wearer can already know the morphological data from previous measurements and enter them into the determination system via a man-machine interface.

[0085] According to certain embodiments of the variant, the intermediate step operation O23 may be performed differently. For example, the electronic memory may contain digital data corresponding to configuration rules associated with each strand of the wrist strap and / or with each subcomponent of the wrist strap, such as links, linkages and clasps. The algorithm may then iteratively generate all possible combinations for a given wrist strap from the rules stored in the memory until converging on an optimal configuration. In a variant, the approach may automatically generate a database of wrist strap data as described above, in which possible configurations are stored.

[0086] According to another particular embodiment of this variant, the determination intermediate step may take into account the optimum configuration of one (or more) watches already worn by the wearer. In this case, this known optimum configuration may be input by the wearer, the retailer or the watchmaker via the man-machine interface of the wrist strap configuration system. This information may potentially be exploited in order to obtain the watch circumference to be considered in step O22 mentioned above. This information may serve as a source for obtaining morphological data about the wearer, or equivalent, according to the embodiment described above with reference to the first obtaining step E1.

[0087] The intermediate step of determining at least one optimal configuration of the wrist strap may include determining at least a wrist strap length adjustment.

[0088] The intermediate step of determining at least one optimum configuration of the wrist strap may include identifying, in the database, wrist strap configuration data that best suits the at least one morphological data item.

[0089] The intermediate step of determining at least one optimal configuration for the wrist strap may include determining configuration data using all or some of the following steps: - Determining the type of wrist strap; and / or - Determination of strands, multiple strands, and / or clasps, and / or - determining the number of links or linkages, in particular the number of extension linkages or links, for at least one strand of the wrist strap; and / or - determining a configuration or configurations of at least one link or at least one linkage for at least one wrist strap strand; and / or - determining the positioning of the end linkages of the wrist strap strands relative to the wrist strap clasp and / or relative to the small watch case; and / or - determining one or more configurations of wrist strap clasps; and / or - Decision for length adjustment or multiple adjustments within the wrist strap clasp.

[0090] The intermediate step of determining at least one optimal configuration for the wrist strap may include displaying the determined optimal configuration on a screen of the configuration system.

[0091] The intermediate step of determining at least one optimal configuration for the wrist strap may include taking into account at least one wearer preference data item, including data regarding how the wearer would like the wrist strap to go around the wrist, and / or data regarding the wearer's lifestyle, in particular the weather conditions where the wearer lives and / or at least one activity in which the wearer is likely to participate, and / or data regarding preferences for the type of wrist strap.

[0092] The intermediate step of determining at least one optimal configuration for the wrist strap may include calculating an amount of slack around the wearer's wrist in accordance with the at least one item of preference data, and / or calculating a variation in an item of morphology data for the wearer over time from the at least one item of preference data.

[0093] The first step of obtaining at least one item of morphological data may include obtaining the dimensions of a portion of the wearer's wrist that is likely to receive the watch, in particular the circumference and / or height and / or width, and / or the dimensions of a portion of the wearer's hand, in particular the circumference and / or height and / or width.

[0094] The first acquisition step may include a first operation of acquiring at least one morphological characteristic of the wearer's wrist, and a second operation of determining at least one morphological data item from the at least one morphological characteristic acquired during the first operation.

[0095] The first operation of acquiring at least one morphological characteristic may include acquiring it from a determination system provided with at least one sensor, such as a camera, laser, or lens, configured to scan, image, or photograph the position of at least one wearer's wrist and / or hand.

[0096] The first acquisition step may involve storing at least one morphological data item via a man-machine interface or via transmission of the at least one morphological data item or a derived data item, such as wrist circumference, from an electronic memory, in particular from a database.

[0097] A second step of preparing the wrist strap may include modifying the wrist strap, particularly from a reference configuration, to achieve the optimal wrist strap configuration c* determined in the intermediate determination step.

[0098] In that alternative, the present invention also relates to a wrist strap configuration system, comprising at least one determination system for determining at least one item of morphological data in order to determine an optimal configuration of a wrist strap based on at least one item of morphological data acquired by the determination system 11, and a computer for performing at least the intermediate step of determining the at least one optimal wrist strap configuration c* as described above.

[0099] In that alternative, the present invention also relates to a method of manufacturing a wristwatch, comprising the steps of selecting a wristwatch or miniature watch case, and configuring a wrist strap onto the miniature watch case into a configuration established by the wrist strap configuration method described above.

[0100] In this alternative, the invention also relates to a data processing device, comprising a computer configured to at least perform the intermediate step of determining the optimal configuration c* of at least one wrist strap as described above, in order to determine the optimal wrist strap configuration based on at least one item of morphological data acquired by the determination system 11.

[0101] Finally, in this alternative, the invention also relates to a computer program comprising instructions which, when executed, cause the program to perform at least the intermediate step of determining an optimal configuration c* of at least one wrist strap as described above in order to determine an optimal wrist strap configuration based on at least one item of morphological data obtained by the determination system 11.
