Description

Technical Field

[0001] The present invention relates to a method for determining at least one form data item related to a wristwatch strap wearer, and a method for configuring a wristwatch strap, particularly its length. The present invention also relates to a system for configuring a wristwatch strap that implements part of the method.

Background Art

[0002] One important operation for the comfort of a wristwatch wearer is to select the best configuration of the wristwatch strap, particularly to achieve the best adjustment of the wristwatch strap length. Of course, the first step is usually to add or remove extension link mechanisms or links to adjust each strand in order to make the wristwatch strap the optimal length. The resulting result is generally not optimal. For this reason, various wristwatch straps are provided with several additional adjustment devices, particularly those having a deployment clasp.

[0003] Specifically, in a wristwatch strap to which a deployment clasp is attached, the clasp is generally provided with a first adjustment device for positioning the wristwatch strap, which is a prior art adjustment device. In addition, existing deployment clasps are provided with a solution that enables a second adjustment of the length of the wristwatch strap, known as a comfort adjustment device, which complements the conventional first adjustment device. Patent Document 1 discloses, for example, a solution that relies on an adjustment link mechanism disposed within the deployment clasp and capable of occupying two stable positions that result in two different strap lengths by rotating. The short position is maintained by a catch on the end link mechanism of the wristwatch strap, and the wristwatch strap is in its short position where the catch engages with the adjustment link mechanism and is elastically immobilized. For this reason, such a solution requires the articulation of several link mechanisms and the catching of the link mechanism to ensure the stability of the short position.

[0004] Finally, there is a solution to achieve fine adjustment of the length of the wrist strap. In practice, the outer circumference of the wrist of the individual wearing the wrist strap is measured using a graduated tape, and then the wrist strap is prepared based on that data. Further, various adjustments may be made that may require a number of repetitions until a theoretically ideal or optimal strap configuration is obtained. Realizing this often relies on the experience of the operator and can prove to be inaccurate and time-consuming.

[0005] Furthermore, when configuring the wrist strap, other data may need to be taken into account, especially when the strap has a buckle, particularly a deployment buckle. A deployment buckle is designed to fasten two strands of a small watch strap around the wrist of its wearer and may include several articulated leaves that can take a first closed position that requires a fastening function to stabilize the closed position and a second release position that allows for attachment and removal of the small watch strap from the wrist. The advantage of such a buckle is that it prevents the watch from falling during removal since the wrist strap strands remain connected at all times. However, the overall dimensions of the wrist strap when deployed in the open position of the deployment buckle must be made hand-accessible. In such cases, as described below, it is advantageous to consider not only the clearance width of the wrist but also the outer circumference of the hand as the "hand clearance width".

DETAILED DESCRIPTION OF THE INVENTION

[0031] For the sake of simplicity and by convention, the term "longitudinal direction" is used in the direction along the length of the list strap strand or the deployment fastener, and the term "transverse direction" is used in a direction perpendicular within the plane of the list strap strand, in other words, in the direction across the width of the list strap strand or the clasp. The vertical direction is a direction perpendicular to the first two directions and perpendicular to the plane of the list strap strand. Further, the term "link" is used for the individual elements of the list strap, and the "link mechanism" is used for a set of links. "List strap" means either the entire list strap, or one or the other of the strands of the list strap, whether or not there is a clasp. Further, the same reference numerals are used to refer to elements that are identical or similar, or have the same function, in various embodiments.

[0032] The present invention is based on a method of constructing a list strap, and one embodiment thereof includes the steps and operations schematically illustrated in FIG. 1.

[0033] The method includes a first step E1 of obtaining at least one morphological data item regarding the wearer of the wristwatch. This method includes, inter alia, a first step E1 of obtaining at least one morphological data item regarding the wearer of the wristwatch at least partially automatically.

[0034] This morphological data item includes the first dimension 1 of the wrist, and may correspond, in particular, to the outer circumference of the wrist of the wearer intended to receive a wristwatch. "Wrist outer circumference" means, as shown in FIG. 2, the outer circumference of the wrist portion p1 where a wristwatch may be received. This first dimension may, as a variant or additionally, be related to the height and / or width of the wrist portion p1. In an advantageous variant embodiment, at least a second morphological data item regarding the wearer may be obtained. The second data item may correspond, in particular, to a second dimension 2 corresponding to the clearance width of the wearer's hand, which is useful in the case of a list strap having a deployment fastener. Here, "hand clearance width" means the area of the maximum outer circumference of the area of the hand portion p2 shown in FIG. 2, such that the list strap with the deployment fastener in the deployed open position can pass through the hand. For this reason, the second dimension 2 may include the outer circumference and / or height and / or width of the hand portion p2. As a variant, other morphological data may also be obtained and used.

[0035] According to one embodiment, the first step E1 of obtaining at least one morphological data item uses, in a first operation O11 of the acquisition first step E1, the digital acquisition system 11 belonging to the equipment 110 of the list strap configuration system, which can automatically acquire at least one morphological feature. "Morphological feature" means 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 acquisition system 11 includes, for example, a camera and enables obtaining a video or one or more images of the form in the wrist area of the wearer and, in some cases, in the hand area according to the advantageous embodiments described. More generally, in an advantageous alternative embodiment, the acquisition system 11 is intended to scan, image, or photograph at least the wrist part p1 of the wearer in order to acquire and / or reconstruct at least one image of the part p1 and may take the form of an image system provided with at least one sensor, for example a lens. The image system according to the advantageous embodiments may also be configured to scan, image, or photograph at least the hand part p2 of the wearer in order to acquire and / or reconstruct at least one image of the part p2. Even more generally, the acquisition system 11 is a system set up to receive and in some cases emit waves in order to acquire at least one feature of at least the wrist part p1 and preferably the hand part p2 of the wearer. For this reason, according to an alternative embodiment of the acquisition system 11, the acquisition system may include at least a device provided with a laser that enables obtaining a group of points forming a contour or a part of the contour of, for example, the wrist part p1 and preferably the hand part p2 of the wearer.

[0037] According to this embodiment, the first operation O11 enables the acquisition system 11 to first determine the part or parts p1, p2 to be considered. For this purpose, the first variant includes transmitting, using a man-machine interface, a numerical display of at least one wrist part p1 and / or hand part p2 to be considered, corresponding to a digital model of the end of the wearer's arm, the model being obtained during the first acquisition step. As a variant, in order to indicate at least one part to be considered, the operator positions an indicator on the wearer's wrist and / or hand before or during digital acquisition. The acquisition 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 acquisition system automatically determines at least one wrist part p1 and / or hand part p2 to be considered by measuring, on the obtained digital model, for example the distance from a part such as the end of the hand identified on the digital model, for example the end of the middle finger, or from a wrist joint, using a computer.

[0038] At the end of the first operation O11, the method performs a second operation O12 of the acquisition step E1 that determines at least one morphological data item from the morphological feature or features obtained during the first operation O11. Specifically, according to the above-described embodiment, the second operation O12 enables accurately determining the outer circumference and / or height and / or width of the wrist part p1 and the outer 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 preferably processed using software means belonging to the acquisition system or another computer of the configuration system, for example a central processing unit, to infer the dimensions 1, 2 that form the required morphological data item. For the sake of simplicity, these dimensions 1, 2 are hereinafter exemplified as morphological data items 1, 2.

[0039] According to an embodiment of the present 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 advantageously form digital data related to the digital model of the wearer's wrist or hand part, or the positioning of several points of the wrist part or hand part, preferably in three dimensions. From these features, the software means can calculate the required morphological data items. This calculation uses, for example, image processing. When the feature includes an image sufficient to visualize the entire contour to be measured to obtain the outer circumference, the calculation consists of adding the lengths of the various parts of the contour obtained separately to reconstruct the morphological data item to be sought. When these 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, the image or 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 when the feature is a point on the contour to be measured. At the end of the second operation O12, the configuration method can automatically and surely construct, automatically and immediately, the morphological data necessary to accurately configure the list strap.

[0040] Of course, the morphological data mentioned in this embodiment are cited as advantageous examples. It is also possible to conceive of other embodiments using only one of these data items, which may or may not be combined with one or more morphological data items of the above-described embodiment, or at least one other morphological data item.

[0041] Furthermore, in addition to the form data, other preference data useful for constructing the list strap may be sent to the list strap configuration system. These data may include, among other things, the preferences of the wearer, particularly regarding the wearing of the list strap. The small watch wearer preference data may include, for example, first preference data 3 related to the desired strap type or multiple strap types, such as, for example, within the range provided in the watch catalog offered by the manufacturer, such as a metal list strap or a flexible list strap, a list strap with or without a deployment clasp.

[0042] These preference data may also include one or more second preference data items 4 related to the lifestyle of the wearer, such as how the wearer desires the list strap to wrap around their wrist, i.e., defining how much slack (play) should exist between the wrist and the list strap, and in some cases, specifically the weather conditions of the wearer's place of residence, and / or at least one activity that the wearer may participate in and is likely to change the dimension 1 of the wrist, such as a sport. The second preference data item 4 may include, among other things, a dimension 1' derived from the dimension 1 related to the wrist part p1, and the dimension 1' can be applied to adapt the dimension 1 related to the wrist part p1 to a specific situation different from the situation of the operation O11, such as after an activity such as participating in a sport. The dimension 1' may be obtained, for example, through predictive analysis based on the form data 1, 2 and in some cases the second preference data 4. In a variant, the derived dimension 1' may be obtained by referring to a pre-prepared database, particularly based on investigations independently conducted by the manufacturer.

[0043] The list strap configuration method according to an embodiment of the present invention then advantageously, but optionally, performs an intermediate step E2 of determining at least one optimal configuration of the list strap suitable for the wearer, and one embodiment thereof will be described below with reference to FIG. 4. This step is advantageously, as will be described below, performed fully or partially automatically. In a variant, this step may be manual.

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

[0045] According to an embodiment, the wearer preference data 3, 4 are likewise sent to the calculation unit of the list strap configuration system to be taken into account.

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

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

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

[0049] Next, according to an embodiment of the present invention, the outer periphery of the small watch obtained only from the form data is adapted again to take into account the wearer preference data. The outer periphery of the small watch obtained above may trigger the determination of the desired outer periphery of the small watch (TDMS).

[0050] Specifically, the preference data may include information on whether the wristwatch is worn tightly or loosely. Depending on the wearer's situation, the outer periphery of the small watch is modified by applying a second weighting factor that can increase or decrease the amount of slack around the wrist. In addition to this, the preference data may be related to the location where the wearer lives or the activities the wearer participates in, which is taken into account by applying other weighting factors or by parameters in the configuration of the wristwatch that enable adjustments to be made to adapt to the specific activity being performed. In the latter case, the wristwatch can be adapted by adjusting the first optimal configuration of the wrist strap to a different second configuration that is optimal for the specific activity.

[0051] In the third operation O23 of the decision intermediate step E2, based on the previously established small watch outer circumference (TDM) or the desired small watch outer circumference (TDMS), the actual configuration of the list strap is finally determined. This operation O23 seeks one or more list strap configurations that correspond to or most satisfy the considered small watch outer circumference. For this purpose, this operation O23 iterates through a list strap configuration database, which includes data on all or most of the existing configurations of the list straps of a given wristwatch, especially according to the first preference data 3, in order to find the optimal configuration c* of the list strap that is most suitable for the considered small watch outer circumference. This optimal configuration is selected from among those that, among other things, enable the small watch case and / or clasp to be placed most centrally or equally on the wearer's wrist part p1. Further, the program additionally proves that, if there is an unfolding clasp, the applied list strap configuration is compatible with the hand part p2 when the unfolding fixture is in the open position. In this way, the method automatically defines an optimal compromise between, regardless of the dimensions of the wearer's hand and wrist, the ability of the wristwatch to properly and comfortably cover the wearer's wrist and provide an opening sufficient to pass the wearer's hand.

[0052] Note that this operation O23 may be repeated according to the first preference data 3, especially according to the different types of desired list straps when there are multiple desired list straps. For this reason, for each type of list strap compatible with the small watch case selected by the wearer, the program may test the various possibilities offered by each list strap in order to establish an optimal configuration for each list strap. For this reason, at the end of the iteration, the program may optionally distribute a numerical display as the most suitable optimal configuration to the form data item or items 1, 2, and optionally to the preference data item or items 3, 4, from among the various optimal configurations of the different list straps.

[0053] In other words, at the end of the iteration, the program adopts the optimal configuration for the list strap that provides the wearer with optimal comfort. The program may also adopt a list strap or a plurality of straps in a configuration that is most suitable for providing the wearer with optimal comfort.

[0054] For each of the types of list straps considered, the program tests various possible configurations for each list strap and proceeds by iteration according to the various possibilities stored in the list strap database to converge to the optimal configuration. Among the configuration options for a given type of list strap, the following are mentioned. - Assuming that there are multiple fasteners compatible with a given type of list strap, determining the fastener and / or - If the type of list strap is composed of links or a link mechanism, for each strand of the list strap, determining the number of links or link mechanisms, especially the number of extension link mechanisms or links, and / or - If at least one link or at least one link mechanism tends to have multiple configurations, determining the configuration or configurations of at least one link or at least one link mechanism for at least one list strap strand, and / or - Determining the positioning of the link mechanism at the end of the list strap strand for the selected list strap fastener and / or for the small watch case, especially to obtain length adjustment, and / or - If multiple configurations are possible for the considered fastener, determining one or more list strap fastener configurations, and / or - Determining length adjustment or multiple adjustments at the connection between the list strap fastener and / or the small watch case.

[0055] Finally, if some types of list straps have configurations that are substantially equivalent and match the characteristics of the wearer, these may be proposed to the wearer, and the wearer may make the final selection of the list strap type.

[0056] In a modified embodiment of the decision intermediate step E2, the calculation unit of the list strap configuration system includes a list strap database containing the correlation between the form data, and optionally the preference data, and the configuration of the type of list strap. For this reason, from the knowledge of the data derived from the acquisition first step, the second operation O22 can directly query the database for the appropriate list strap configuration or configurations for each type of list strap. In this modification, the program in the computer selects the optimal small watch-strap configuration or configurations c* that are most suitable for the wearer's form and optionally the wearer's preference for a predetermined model of the small watch case selected by the wearer.

[0057] At the end of the decision intermediate step E2, the optimal small watch-strap configuration or configurations c* that are most suitable for the wearer's form and optionally the wearer's preference are transmitted to the watchmaker, to the retailer, or to the manufacturer, etc., and also to the wearer via the man-machine interface of the list strap configuration system. This transmitted information may include all details regarding the adjustment and options of the adopted type of list strap, including: - the selected strand or strands, and / or - the selected fastener, and / or - the link mechanism or links added and / or removed to / from one or the other of the strands, and / or - the link mechanism or links to be configured in a predetermined configuration, and / or - the link mechanism or links to be moved with respect to the strand, especially the fastener, and / or with respect to the small watch case, and / or - the length adjustment of the length adjustment link mechanism within the fastener and / or within the connection portion with the small watch case.

[0058] ​Here, it is noted that the intermediate decision step E2 may determine several optimal configurations for different types of list straps that may have an equal optimal configuration, or for a single list strap, according to different specific usage scenarios.

[0059] Next, the method of configuring the list strap includes a second step E3 of preparing the list strap for the wearer according to the optimal configuration determined in the previous step. For this purpose, a watchmaker, or any individual qualified to perform the second preparation step E3, performs the final fitting and / or final adjustment of each list strap strand based on the detailed information determined and transmitted at the end of the previous step. As a result of this final step, the method of configuring the list strap according to the present invention can also be regarded as the final step in the method of manufacturing the list strap, or in the method of final fitting or adjusting the list strap.

[0060] According to an advantageous embodiment, the list strap configuration system has a man-machine interface and transmits one or more images for assisting in the final configuration of the list strap, as shown in FIG. 5.

[0061] According to one example, the selected list strap may be transported and stored in a predetermined configuration, in which case the second step E3 consists of changing the list strap from the predetermined configuration to the optimal configuration established in the determination intermediate step E2.

[0062] In the second step, a watchmaker or any individual having the qualification to perform the second step can, in the first operation O30, select at least one list strap strand 6 from among n strands of different lengths. Thereafter, at least one list strap length setting device 5 may be executed. This may be, for example, means 51 that enables the attachment or removal of an extension link mechanism or link to the list strap strand to achieve the best adjustment of the length of the strand and, more generally, of the list strap, or other means 52, 53 that enable the link or link mechanism of the strand to be configured in a predetermined configuration, or that enable the configuration of the position of the strand with respect to the buckle or the small watch case.

[0063] In the special case of a metal or partially metal type list strap provided with a link mechanism, the watchmaker may, in the second operation O31 shown in FIG. 6, add or remove a link or link mechanism 61 from the first strand 6 of the list strap and / or from the second strand 6' of the list strap using means that enable easy removal / reattachment, such as a screw 7, especially an elastic screw. Preferably, the second operation O31 is performed exclusively by the watchmaker.

[0064] In the third operation O32 shown in FIG. 7, the watchmaker may position the end of a strand 6 of the list strap at a predetermined position with respect to the cover 8 of the deployment buckle 80 using a device 53 that holds the link mechanism 62 in place, for example, via a notch 81 system. The notch system may include, for example, a cover 8 provided with a indexing tooth 82 system designed to cooperate with a protrusion 63 of the strand 6. Such a device may of course be operated not only by the watchmaker but also by the wearer of the wristwatch. Alternatively or additionally, one link or link mechanism may be indexed with respect to the cover of the buckle via a bar that can be arranged at a plurality of predetermined positions of the cover (not shown).

[0065] In the fourth operation O33 shown in FIG. 9, the horologist may configure the extension link mechanism or link to a first or second configuration to extend or shorten the first and / or second list strap strands. For example, the adjustment link mechanism 64 is provided with two articulated shafts A1, A2 respectively connected to the cover 8 of the deployment clasp 80 and the end link 65 of one strand 6 of the list strap. The connection link mechanism 64 is pivotable with respect to the first shaft A1 connected to the cover 8 of the deployment clasp 80 in order to move the second shaft A2 connected to the end link 65 to one side or the other side of the first shaft A1 to define two determined lengths of the list strap. The end link 65 connected to the adjustment link mechanism 64 includes a notch 66 that can be elastically immobilized with respect to the adjustment link mechanism 64 when the adjustment link mechanism 64 is in a position corresponding to the short configuration of the list strap. FIG. 8 illustrates the device when the list strap is in the short configuration, and FIG. 9 illustrates the device in the process of being actuated.

[0066] Also, a fifth operation O34 of selecting the deployment clasp 80 from n different-sized clasps can be performed. For example, in the case of a deployment clasp provided with leaves 71, 72 as shown in FIG. 10, different-sized leaves may be provided so as to fit maximally to the form of the wearer of a small watch. Such a deployment clasp may include two leaves. Alternatively, the deployment clasp may include more than two leaves, for example three leaves, for the purpose of obtaining a maximized deployment that allows the wearing or removal of the wristwatch regardless of the size of the wearer's hand, especially the position p2 of the wearer's hand. Additionally or alternatively, such a clasp may include at least one leaf having at least a portion that can have two predetermined configurations when the clasp is operated to make it easier for the wearer's hand, especially the position p2 of the wearer's hand, to pass through.

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

[0068] Of course, all of these operations are optional and there is not necessarily a hierarchical order. Therefore, in order to change from the predetermined configuration of the wristwatch to the optimal configuration c* of the list strap, the watchmaker may perform, for example, all or some of the above-described operations O30, O31, O32, O33, O34.

[0069] The method is not limited to the type of list strap having a metal link mechanism. In the case of a flexible list strap where the strands 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 preferably carried out before any other operation. All or some of the operations O31, O32, O33, O34 may also be carried out, but are not essential. Specifically, one end of the flexible strand may be positioned at a predetermined position relative to the clasp, in particular relative to the cover of the deployment clasp. The flexible strand may be reduced to a single strand. Alternatively, the flexible strand may be connected to the deployment clasp via one or more metal links. The clasp of the "flexible list strap" may potentially include a leaf and / or a cover. Alternatively, the clasp may be reduced to a buckle, in particular a buckle-fastening (or more generally any non-deployment clasp). In the latter case, the preparation second step E3 may be reduced to cooperating with means such as holes formed in the strand identified during the determination intermediate step E2 and selected during the first operation O30.

[0070] The present invention also relates to a list strap configuration system employing the above-described configuration method. The list strap configuration system includes at least one acquisition system 11 for acquiring at least one form data item and, optionally, a computer of a computing unit for performing the above-described determination intermediate step E2 in order to determine the optimal configuration of the list strap according to at least one form data item acquired by the acquisition system 11.

[0071] The acquisition system 11 is configured to receive waves and, in some cases, send waves in order to acquire at least one morphological feature of the wearer of the list strap. Advantageously, the acquisition system 11 additionally includes 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 on the wearer's forearm by projection, thereby making it possible to create a model of the wearer's forearm. The acquisition system 11 may additionally include a computer configured to calculate at least one morphological data item from at least one morphological feature acquired by the acquisition system using the method described above. Finally, the acquisition system 11 may preferably include a man-machine interface configured to receive an input of at least one data item regarding the wearer of the list strap. In a variant, the man-machine interface may also display a digital model of the wearer's forearm, for example enabling the wearer to participate in the determination of, for example, the wrist part p1 and the hand part p2, or simply display the automatically identified part. The acquisition system may be connected to a central processing unit through a communication device.

[0072] The present invention also relates to such an acquisition system itself, which takes the form of a portable object, for example, and includes a computer configured to execute at least the first acquisition step E1 of the method described above. The present invention also relates to a computer program including instructions for causing the program to execute at least the first acquisition step E1 when the program is executed.

[0073] Optionally, the acquisition system and the central processing unit are arranged close to or within the same equipment. They may share a single and common computer. In this way, the configuration system, or at least the acquisition system, preferably forms an equipment 110 in the shape of a small equipment that is advantageously easily transportable and / or easily installable in a retail store. Optionally, the equipment 110 can be operated by a watchmaker or retailer, and in particular, through a purchasing experience that is entertaining and does not require excessive time, it is associated with the wearer of the wristwatch. It takes the shape of a mobile phone or smartphone, tablet, or a pair of glasses. Alternatively, the equipment device is a tool belonging to the wearer that enables remote purchasing, for example, from home, away from the retail store.

[0074] As described above, the central processing unit that preferably executes the decision intermediate step E2 is preferably integrated within the same first equipment 110 used in the first step E1. Alternatively, it may be a separate entity such as a desktop computer. In this case, the acquisition system is connected to the computer, preferably automatically, through a communication device for transmitting data locally acquired and / or processed within the acquisition 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 smartphone. The central processing unit that executes the second step E2 may be locally present in the entertainment equipment and may be a remote unit housed by the manufacturer, for example, connected to at least one acquisition system through a communication device.

[0075] Finally, the list strap configuration system includes one or more electronic memories, especially for accommodating the database mentioned in the description of the method. The electronic memory or memories are connected to the middle processing unit through one or more communication devices. Such a memory may be integrated within the small equipment forming the configuration system, or alternatively, may be remotely connected to the central processing unit or the acquisition system through a communication device.

[0076] The method according to the present invention has been described along the scenario enabling the configuration of the list strap in the sale of a specific model of a wristwatch. Of course, the method may also be executed to notify the wearer of the wristwatch of the optimal configuration c* of the list strap even after the sale or independently of the sale of the wristwatch.

[0077] Alternatively, the present invention relates to a method for configuring a wristwatch list strap for a given wearer, the method comprising: - a first step of obtaining at least one morphological data item 1, 2 regarding the wearer of the list strap, - an intermediate step of automatically determining at least one optimal configuration c* of the list strap suitable for the wearer from the at least one morphological data item 1, 2 obtained in the previous step, - a second step of preparing a list strap for the wearer in the optimal configuration determined in the previous step steps.

[0078] In this alternative, the determination intermediate step corresponds to the above-described, automatically executed, determination intermediate step.

[0079] According to a variant of this alternative, the first acquisition step E1 of the method can be simplified. For example, the step may be executed using a conventional system of the tape measurement type. Such a tape may or may not be retracted by an elastic device. Alternatively, the wearer may already know the morphological data from previous measurements and input those data into the acquisition system via a man-machine interface.

[0080] According to a specific embodiment with such a variant, the operation O23 of the intermediate step may be performed differently. For example, the electronic memory may include digital data corresponding to each strand of the list strap and, and / or each sub-component of the list strap such as links, link mechanisms and fasteners, and the relevant configuration rules. Next, the algorithm can form all possible combinations for a given list strap from the rules stored in the memory by iteration until convergence to the optimal configuration. In a variant, the approach can automatically form a database of the above-mentioned list strap data, and possible configurations are stored in the database.

[0081] According to another specific embodiment of the variant, the determination intermediate step may consider the optimal configuration of one (or more) wristwatches that the wearer is already wearing. In this case, this known optimal configuration may be input by the wearer, retailer, or watchmaker via the man-machine interface of the list strap configuration system. This information may potentially be utilized to obtain the small watch outer circumference to be considered in step O22 above. This information may also serve as a source for obtaining morphological data regarding the wearer, or an equivalent thereof, according to the embodiments described above with reference to the first acquisition step E1.

[0082] The intermediate step of determining at least one optimal configuration of the list strap may include determining at least the list strap length adjustment.

[0083] The intermediate step of determining at least one optimal configuration of the list strap may include identifying the list strap configuration data in the database that is most suitable for at least one morphological data item.

[0084] The intermediate step of determining at least one optimal configuration of the list strap may include determining the configuration data using all or some of the following steps. - Determining the type of the list strap, and / or - Determination of a strand, a plurality of strands, and / or a fastener, and / or - Determination of the number of links or link mechanisms, in particular the number of extension link mechanisms or links, for at least one strand of a list strap, and / or - Determination of the configuration or configurations of at least one link or at least one link mechanism for at least one list strap strand, and / or - Determination of the positioning of the end link mechanism of a list strap strand with respect to a list strap fastener and / or with respect to a small watch case, and / or - Determination of one or more configurations of a list strap fastener, and / or - Determination of length adjustment or adjustments within a list strap fastener.

[0085] An intermediate step of determining at least one optimal configuration for a list strap may include the step of displaying the determined optimal configuration on a screen of a configuration system.

[0086] An intermediate step of determining at least one optimal configuration for a list strap may include taking into account at least one wearer preference data item including data regarding how the wearer desires the list strap to wrap around the wrist, and / or data regarding the wearer's lifestyle such as in particular the weather conditions of the wearer's place of residence and / or at least one activity the wearer may participate in, and / or data regarding the preference for the type of list strap.

[0087] An intermediate step of determining at least one optimal configuration for a list strap may include calculating the amount of slack around the wearer's wrist according to at least one preference data item, and / or calculating the variation of the morphological data item regarding the wearer over time from at least one preference data item.

[0088] The first step of obtaining at least one morphological data item may include obtaining the dimensions of the wearer's wrist portion where the wristwatch may be received, particularly the outer circumference and / or height and / or width, and / or the dimensions of the wearer's hand portion, particularly the outer circumference and / or height and / or width.

[0089] The first step of obtaining may include a first operation of obtaining at least one morphological feature of the wearer's wrist and a second operation of determining at least one morphological data item from the at least one morphological feature obtained during the first operation.

[0090] The first operation of obtaining at least one morphological feature may include obtaining from an acquisition system provided with at least one sensor, such as a camera, a laser, or a lens, configured to scan, image, or photograph at least one wearer's wrist and / or hand position.

[0091] The first step of obtaining may include storing at least one morphological data item via a man-machine interface or via the transmission of at least one morphological data item or a derived data item such as the outer circumference of the wrist from an electronic memory, particularly from a database.

[0092] The second step of preparing the list strap may include changing the list strap, particularly from a reference configuration, in order to achieve the optimal list strap configuration c* determined in the determination intermediate step.

[0093] In this alternative, the present invention also relates to a list strap configuration system including at least one acquisition system for determining at least one morphological data item and a computer for at least performing the intermediate step of determining the at least one optimal list strap configuration c* as described above, based on at least one morphological data item acquired by the acquisition system 11.

[0094] In this alternative, the invention also relates to a method of manufacturing a wristwatch, the method comprising the steps of selecting a wristwatch or a small watch case, and configuring a list strap onto the small watch case in a configuration established by the above-described list strap configuration method.

[0095] In this alternative, the invention also relates to a data processing device comprising a computer configured to at least perform an intermediate step of determining an optimal configuration c* of at least one of the above-described list straps in order to determine an optimal list strap configuration based on at least one morphological data item acquired by the acquisition system 11.

[0096] Finally, in this alternative, the invention also relates to a computer program which, when the program is executed, includes an instruction to at least cause the program to perform an intermediate step of determining an optimal configuration c* of at least one of the above-described list straps in order to determine an optimal list strap configuration based on at least one morphological data item acquired by the acquisition system 11.
