Abstract
The present invention concerns a device for securing a back cover (6) to a middle part (28) of a watchcase (26), the back cover (6) having a screw thread (8) on its outer periphery, the device being characterized in that it includes an intermediate element (1) including a resilient blocking element (4) and a metal element (2) concentric to the resilient blocking element (4), this intermediate assembly being forcibly driven into the lower part of the middle part (28) of the watch (26), and the back cover (6) being screwed onto the metal element (2) so that, when the back cover (6) is completely screwed onto the metal element (2), the metal element (2) can be pivoted by sliding on the resilient blocking element (4) to a stop point from which the resilient blocking element (4) can in turn pivot by sliding on the middle part (28) of the watch (26), allowing the alignment of the back cover (6) to be adjusted with respect to the vertical 12 o'clock-6 o'clock axis of the watch (26).
