Abstract The method for assembling and fixing a casing ring (3) in a watch case (6) uses a ring made of plastically deformable material fitted with means (60, 70) forming a single piece with the ring and capable of positioning it with respect to the case. The ring is introduced into the case, which causes said positioning means to be deformed plastically. The introduction is interrupted when the ring occupies a determined position with respect to the case.
