According to one embodiment, the first part has an inclined surface 22, preferably at 45 ° relative to the plate 12 of the display and the second part has a recess 23 located under the inclined surface 22 and in which a section of the rod corresponding fixing 50a, 50b is held under the action of a return member 24 to maintain the carriage 18 in a locked position.

Referring in particular to FIGS. 5 and 6, an unlocking device is arranged on the side of the second face 12b of the plate 12 of the display. This device comprises an actuator 30 for displacing a carriage 18 in translation. The carriage 18 comprises two branches 20a, 20b arranged along each longitudinal side of the main portion 14a of the rectangular opening 14 of the plate 12 respectively in a first and a second slide 26a, 26b. The carriage 18 also comprises a central part 19 arranged on one of the lateral sides of the opening 14 and connecting the two branches 20a, 20b of the carriage 18. According to an advantageous embodiment, each branch 20a, 20b of the carriage 18 is integral with the corresponding locking member 21. According to an alternative embodiment, each branch 20a, 20b of the carriage 18 is integral with the corresponding locking member 21.

The actuator 30 of the unlocking device comprises an electric motor 32 whose output is connected to a worm screw 34. An actuator 36 is mounted on the worm 34. This actuator 36 can for example being a simple nut arranged to move in translation along the endless screw 34. This actuating element 36 is in contact or slightly recessed with one of the edges of the central part 19 of the carriage 18 when that -this is in a locked position.

In order to move the carriage 18 from a locking position to an unlocking position of the removable support 40, the electric motor 32 is controlled so as to rotate the worm screw 34 in a first direction of rotation to move the actuating element 36 along the worm screw 34 in the direction of the carriage 18. The latter is moved, under the action of the actuating element 36, from the locking position to the position of unlocking in which the two locking members 21 are released from the two fixing elements 50a, 50b of the removable support 40. In this position, the removable support 40 can be detached from the tray 12 of the display.

The plate 12 of the display 10 and the removable support 40 may each be provided with one or more sensors intended to send a signal when the removable support 40 is not locked in the main portion 14a of the opening 14 of the tray 12 of the display and when the wristwatch is no longer on the removable support 40. According to one embodiment, the display 10 may include a display (not illustrated) configured to indicate more information, in particular the status of the connection, namely whether the removable support 40 is locked or not in the main portion 14a of the opening 14 of the tray 12 of the display stand and if the wristwatch is on the removable support 40 when the latter is locked to the tray 12 According to one embodiment, the plate 12 of the display stand and the removable support 40 can comprise a wireless communication system of restricted range, for example according to the Bluetooth protocol . An electronic circuit (not illustrated) can be mounted on the side of the second face 12b of the tray 12 of the display stand and / or inside the removable support 40 so as to emit an audible alarm when the removable support 40 leaves a perimeter around 10 to 30 meters around the shelf 12 of the display.

In order to return the carriage 18 from the unlocking position to the locking position, the electric motor 32 is controlled with reverse polarity so that the worm screw 34 is actuated in a second direction of rotation opposite to first direction of rotation to return the actuating element 36 to its initial position corresponding to the locking position of the carriage 18. The actuating element 36 being released from the carriage 18 in its initial position, the carriage 18 is returned to the locking position under the action of the return member 24. According to this configuration, the removable support 40 can again be inserted and locked in the main portion 14a of the opening 14 of the tray 12 of the display as explained above.

According to one embodiment, the return member 24 is in the form of a tension spring, one end of which is connected to an attachment part 25a of the carriage 18 and the other of the ends is connected to a fastening element 25b mounted on the second face 12b of the plate 12 of the display. The return member 24 can of course take other forms to perform this return function when the actuating element 36 is in a disengaged position from the carriage 18, for example by means of compression springs arranged at each end free of the two branches 20a, 20b of the carriage 18 to exert a stress in the direction of the actuating element 36.

More generally, the location and shape of the fastening elements 50a, 50b as well as the configuration of the locking members 21 are not limited to the embodiment which has just been described, By way of 'example, the removable support 40 may have only one fixing element in the form of a hook arranged in the center of the lower wall 46a of the removable support 40 while a single locking member, identical to that which comes from 'be described, is centered in the main portion 14a of the opening 14 of the plate 12 to cooperate with the hook. In this example, the shape of the carriage of the unlocking device is adapted accordingly and may comprise only a single branch centered at the main portion 14a of the opening 14 of the plate 12.

The display according to the invention is particularly well suited to be installed in store windows since the unlocking device and the on-board electronics necessary to perform various functions mentioned above are arranged on the side of the second face 12a of the tray 12 of the display. This display can therefore be mounted so, on the one hand, to make visible only the first face 12a of the plate 12 for aesthetic reasons, and on the other hand, to make inaccessible the second face 12b for security reasons.
