| 101 | Mounting of a case band and a crystal bezel in a watch | US579326 | 1975-05-20 | US3979902A | 1976-09-14 | Tsutomu Miyasaka; Yoshiaki Fujimori; Youjiro Okakura |
| A watch case in which a bezel of a crystal and a case band are removably secured together by engagement of a plate spring secured to the bezel with an inclined surface of the case band. A waterproof relation can be obtained between the bezel and the case band by providing a gasket between the bezel and the case band. The plate opening has one portion secured in a recess of the bezel and a bent portion engaging the inclined surface. | ||||||

| 104 | Watertight watchcase | US42185373 | 1973-12-05 | US3831372A | 1974-08-27 | ISONO S |
| A watertight watchcase having a watertight first elastic ring seal without adhesive between a watch crystal and a watch crystal ring circumferentially of the ring seal and watch crystal. The watch crystal ring is provided with two flange surfaces remote from the first ring seal and lying in two planes normal to each other. A second elastic ring seal is received against these two surfaces and compressed thereagainst by a circumferential shoulder on a watchcase band effecting a second watertight seal without adhesive between the watch crystal ring and the watchcase band. A bezel is applied against the watch crystal ring circumferentially thereof compensating for the restoration forces of the elastic ring seals.

| A waterproof watchcase having a watch crystal sealed with a bezel circumferentially thereof. The seal is effected by a sealing ring, made of an elastic material, without use of adhesives. The sealing ring has a body provided with a first circumferential annular flange on one side of the body and on an opposite side, in a plane offset from the plane within which the first flange lies, is disposed a second annular flange integral with the body. The bezel compresses the first annular flange between it and the periphery of the watch crystal effecting a waterproof seal therebetween. A tension ring is disposed internally of the second flange and cooperates with a watchcase band externally thereof for compressing the second annular flange therebetween and effecting a watertight seal. The back of the watchcase is closed by a back cover and a gasket cooperative with the watchcase band in effecting a water-tight seal so that the watch is completely waterproof.

| 106 | Fluid tight mounting of crystal in watch case | US29367572 | 1972-09-29 | US3817025A | 1974-06-18 | SIEGRIST E |
| A crystal is secured in a watch case in a fluid tight manner by means of a bushing of compressible semirigid material such as nylon. The bushing fits into an annular recess at the front of the watch case and is pressed tightly against an annular wall of the recess by a compression ring which fits into an inner portion of the bushing and overlies the peripheral portion of the watch dial. The crystal fits into an outer portion of the bushing and is positioned axially by the compression ring. A tension ring surrounds an outer portion of the bushing and presses it tightly against the periphery of the crystal to provide a fluid tight seal.

| 107 | Water-proof wrist watch case having non-circular glass profile | US3735585D | 1971-06-23 | US3735585A | 1973-05-29 | TAKAGI T |
| A watch glass having a non-circular glass element laminated on an ordinary round glass element. The watch glass is placed on a main body of the watch case with an O-ring interposed therebetween and a rim member having an inner profile complementary to the profile of said non-circular glass element is force-fitted over the main body of the case to surround said non-circular glass element, whereby the non-circular glass element only of the watch glass is exposed to the surface of the watch case.

| 108 | Watertight watchcase for wristwatches | US3640065D | 1970-02-16 | US3640065A | 1972-02-08 | LEDERREY MARC; GRENCHEN CANTON |
| An internal capsule constituted by a vessel made of a soft plastic material and by the watchglass is kept closed by an external capsule constituted by two metallic pieces fixed onto one another by screws. These pieces press the glass axially on the upper edge of the lateral portion of the plastic vessel so as to form a tight seal therebetween. The watch movement is held in place within the internal capsule by clamping. The lateral portion of the plastic vessel is therefore transversely compressed between the movement and one of the metallic pieces of the outer capsule.
