A watch case includes a capsule receiving a watch mechanism, arranged along a main axis, and which includes a front side that has the watch face. The watch case further includes a middle surrounding the capsule and provided with an essentially cylindrical housing open toward the back from which side it receives the capsule. The watch case further includes a bezel placed against the back of the capsule. The bezel includes tabs arranged on the outer contour of the capsule, which are in a blocking position partly inserted in the interior of at least one groove having a circular orientation, produced in the cylindrical part of the housing of the middle.

The invention concerns a box including a device for retaining in position a timepiece component. The device includes: a base (2); a support (3, 4) comprising a first part (3) and a second part (4), the first part being mounted to be mobile relative to the second part; a first contact element (3a, 3b) intended to come to bear against the timepiece component, the first contact element (3a, 3b) being mounted on the first part, and a second contact element (4a) intended to come to bear against the timepiece component (5), the second contact element (4a) being mounted on the second part (4); anda control member (1) mounted to pivot on the base (2) about a first axis (1a) on the one hand and pivoting the first part about a second axis (1b) on the other hand.
