Abstract
Abstract The watch case comprising a middle (2) containing a lining (4) and a back (9) detachably mounted in a lower opening of the middle by means of a pressure device. A band (12) of synthetic material constituting a seal is formed on the periphery of the opening, that band being made in one piece with the lining and connected to it by portions of synthetic material crossing appropriate passages (15) of the middle. The side walls (16) of the opening are at least partially devoid of lining and they work together with opposite surfaces (17) of the back in order to assure pressure coupling of the latter and compression of the band (12).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A watch case comprising a middle containing a lining of synthetic material and at least one detachable part detachably mounted in an opening of the middle by means of a pressure device, wherein a band of synthetic material constituting a seal is formed on the periphery of the opening, the lining and the band being made in one piece and connected by portions of synthetic material crossing passages of the middle, the opening having side walls which are at least partially devoid of lining and form a coupling surface together with an opposite surface of the detachable part to assure pressure coupling of the detachable part and compression of the band of synthetic material, said passages comprising vertical grooves made in the side walls of the opening, said vertical grooves being separated by unlined wall zones.
Claim 2
Dependent Claim
136 words
A watch case comprising a middle containing a lining of synthetic material and at least one detachable part detachably mounted in an opening of the middle by means of a pressure device, wherein a band of synthetic material constituting a seal is formed on the periphery of the opening, the lining and the band being made in one piece and connected by portions of synthetic material crossing passages of the middle, the opening having side walls which are at least partially devoid of lining and form a coupling surface together with an opposite surface of the detachable part to assure pressure coupling of the detachable part and compression of the band of synthetic material, said passages comprising vertical grooves made in the side walls of the opening, said vertical grooves being separated by unlined wall zones.
Claim 3
Dependent Claim
18 words
A watch case according to claim 1, wherein the detachable part comprises a back of the watch case.
Claim 4
Dependent Claim
25 words
A watch case according to claim 1, further comprising a bezel connected to the top of the middle, said bezel bearing against said synthetic material.
Claim 5
Dependent Claim
39 words
A watch case according to claim 2, wherein the lining extends cantilevered radially inwardly above the unlined wall zones to form a lateral support for a watch movement placed in the case and a vertical support for its dial.
Claim 6
Dependent Claim
39 words
A watch case according to claim 2, wherein said back comprises a peripheral skirt, the dimensions of which leave only a slight space between the opposite surfaces of the skirt and of a watch movement placed in the case.
Claim 7
Dependent Claim
62 words
A watch case according to claim 1 wherein the material forming said lining inside the metal passes thereto through said opening, said material curing and forming said lining, the side walls of the opening then being machined to form said coupling surface while the synthetic material contained in the grooves and in the unlined zone is simultaneously machined to form said band.
