-jo Les dispositifs de repérage sont habituellement disponibles sous forme de balises transportables capables de flotter et de taille moyenne dont l'encombrement et la structure d'emport sont propres à la dissuasion de la permanence du port, et donc de la disponibilité de ce dispositif en toute circonstance sans précaution préalable, tel que l'emport préalable d'une s balise portable de détresse, ou port de gilet de sauvetage et autre vêtement de protection thermique ou flottant qui seraient munis d'un tel dispositif de repérage. Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet selon une première caractéristique, un 2o boîtier muni d'un bracelet pouvant être fixé au poignet. Ce boîtier contient un dispositif d'émission activé volontairement ou automatiquement selon la programmation préalablement effectuée. L'activation du dispositif d'émission est obtenue par pression sur un bouton ou par un programmateur  -jo The tracking devices are usually available in the form of transportable beacons capable of floating and of medium size whose size and carrying structure are specific to dissuading the permanence of the port, and therefore the availability of this device in all circumstances without prior precautions, such as the prior carrying of a portable distress beacon, or wearing of a life jacket and other thermal or floating protective clothing which would be fitted with such a tracking device. The device according to the invention overcomes this drawback. According to a first characteristic, it comprises a 2o case provided with a bracelet that can be attached to the wrist. This box contains a transmission device activated voluntarily or automatically depending on the programming previously carried out. The transmission device is activated by pressing a button or by a programmer
