1. A method for manufacturing a wristwatch having a watch case and a wriststrap, the wristwatch being configured for a given wearer, wherein the method comprises:
firstly, acquiring at least one morphological data item pertaining to the wearer of the wristwatch, the acquiring being performed by a first item of equipment of an acquisition system located at a location of a wearer, and transmitting data representing the at least one morphological data item toward a second item of eqiupment of a configuration system located remotely from the acquisition system, the transmitting being performed by a communication device of the acquisition system;
secondly, automatically determining at least one optimal configuration for the wriststrap suited to the wearer, the automatic determining being performed by the second item of equipment of the configuration system located remotely from the acquisition system, the automatic determining comprising at least determining a length adjustment of the wriststrap, from the at least one morphological data item received from the acquisition system, the automatic determining of the at least one optimal configuration for the wriststrap comprising determining configuration data using at least one of the following:
determining a wriststrap type;
determining a wriststrap strand or strands;
determining a wriststrap clasp;
determining a number of links or linkages for at least one wriststrap strand;
determining a configuration or configurations of at least one link or of at least one linkage for at least one wriststrap strand;
determining a positioning of an end linkage of a wriststrap strand relative to a wriststrap clasp, relative to a watch case, or relative to both wriststrap clasp and the watch case;
determining one or more configurations of a wriststrap clasp;
determining a length adjustment or adjustments within a wriststrap clasp,
wherein the automatic determining of the at least one optimal configuration of the wriststrap suited to the wearer, from the at least one morphological data item, is performed automatically using a computer program of the configuration system,
wherein the computer program applies a first weighting coefficient to determine a circumference of the wristwatch case allowing the wristwatch to fit a geometrical shape of a wrist the wearer with an optimal amount of slack; and
thirdly, preparing the wristwatch for the wearer to the optimal configuration determined in the automatic determining, the preparing comprising assembling the wriststrap having at least one optimal configuration determined in the automatic determining and assembling the wriststrap with the wristwatch case having the optimal circumference determined in the automatic determining, the assembling being performed by at least one assembler located remotely from the location of the wearer.
