Claim Text:
1. A watch with a rigid casing-up, comprising: a middle; a bottom; a movement; a casing-up ring in contact with the middle; and a tightening element; in which: the casing-up ring has an inner peripheral face, wherein a profile of the inner peripheral face of the casing-up ring comprises at least one zone Z, the tangent (T) to which forms a first non-zero angle (α) of less than 90 degrees with an axis (X) passing through a center of the movement and perpendicular to a plane formed by the movement; the movement has an outer peripheral face, wherein a profile of the outer peripheral face of the movement comprises at least one zone Z′, the tangent (T′) to which forms a second non-zero angle (α′) of less than 90 degrees with the axis (X); the inner and outer peripheral faces are in contact with each other in the Z and Z′ zones, the tightening element is configured to apply a pressure on at least one of the movement and the casing-up ring, and in an assembled state of the watch, one of the movement and the casing-up ring is position-adjustable in an axial direction by frictional sliding contact between the zones Z and Z′, and the other one of the movement and the casing-up ring is blocked against an abutment, so that the movement is subject to an adjustable tightening pressure in simultaneously the axial direction and a radial direction.
