Problems solved by technology

[0005] While it is possible to insert a shock absorber such as an elastic collar between the case and the movement, this requires a lot of free space inside the case

Embodiment Construction

[0050] exist figure 1 Shown in the middle is a watch with a rigid assembled case according to a first embodiment of the invention.

[0051] The watch comprises a middle part 1 , a detachable base 2 , a movement 3 , an assembled case ring 4 and fasteners 5 .

[0052] The assembled case lining 4 for the movement is generally composed of a hard and non-elastic material with a Young modulus typically greater than 0.1 GPa and preferably greater than 50 GPa.

[0053] figure 2 The invention is shown in more detail. The ring preferably comprises a split 6 breaking its circumference. The splits 6 allow an improved elastic deformation of the ring, the free end boundaries of the splits 6 being able to move closer to each other, in this way reducing the inner diameter of the ring. Furthermore, the split 6 allows the passage of parts of the watch, such as the winding stem. The assembled case lining 4 also includes a frusto-conical inner peripheral surface 8 .

Abstract

The watch has a movement (3) in contact with a middle (1) and in contact with a cover. A casing ring (4) is in contact with the middle. The casing ring includes an inner peripheral face e.g. truncated cone-shaped inner peripheral face (8), with a profile provided with a region. The movement is secured to an outer peripheral face e.g. truncated cone-shaped outer peripheral face (7), whose profile includes another region. The inner and outer peripheral faces are in contact with each other in the regions. An independent claim is also included for a method for casing a movement of a watch.

Description

technical field [0001] The invention relates to a watch with a rigid assembled case, and a method of case-assembling such a watch. Background technique [0002] The case assembly of the movement is usually completed by means of a sling that is inserted into a groove on the inner peripheral surface of the case and screwed into the movement or by means of a lining ring that assembles the case, that is, the movement is fixed in the case of the watch . [0003] In European patent application EP1 970 779 it is proposed to use two superimposed case-building rings for case-assembly, wherein the movement is held between these two superimposed case-building rings. These collars are themselves squeezed between the middle part of the watch and the base of said watch. One of the rings is provided with an opening allowing the passage of the winding stem. An annular joint is provided for the axial and radial retention of the second ring, so that the movement is also axially and radiall...
