Watch with a rigid casing-up, and casing-up method

摘要

The invention relates to a watch with a rigid casing-up, comprising: a middle (1); a bottom (2); a movement (3, 3bis, 3ter, 3quater, 41); and a casing-up ring (4, 4bis, 4ter, 42) in contact with the middle (1). The casing-up ring (4, 4bis, 4ter, 42) has an inner peripheral face (8, 17) and the movement (3, 3bis, 3ter, 3quater, 41) is secured to an outer peripheral face (7, 13, 18, 18bis), said inner (8, 17) and outer (7, 13, 1, 18bis) peripheral faces being in contact with each other in the Z and Z′ regions thereof. Said watch is characterized in that it also comprises a tightening element (5, 5bis) provided for exerting pressure on the casing-up ring (4, 4bis, 4ter, 42) or the movement (3quater). The invention also relates to a method for casing-up such a watch.

主权项

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.
