| 141 | Leakproof watch case | US612828 | 1984-05-22 | US4544284A | 1985-10-01 | Michel Geiger; Gaston Gagnebin; Jacques Ackermann |
| A wrist-watch case includes a back that is screwed onto a spacer ring and an assembly of two caps and a crystal that forms one piece attached to the case-band by screws fastened into the caps from the underside of the case-band. This construction makes it possible to integrate a bracelet perfectly with the case through the caps, each cap forming an end link having the same appearance as the articulated links of the bracelet and adjoining the beveled edge of the crystal. This construction is particularly well adapted to the use of caps and links made entirely of hard metal. | ||||||
| 142 | Waterproof watchcase with multi-layered resin-coated glass | US577862 | 1984-02-07 | US4509866A | 1985-04-09 | Gen Mitamura |
| A waterproof watchcase-and-glass assembly has a plurality of superimposed resin layers coated on the glass in the region where the glass contacts the case to obtain a watertight connection between the case and glass. The innermost resin layer, which is in contact with the glass, has superior adhesion to glass and a lower hardness than the outermost resin layer, which is in contact with the case. | ||||||

| 144 | Water-resisting structure for a watch | US525108 | 1983-08-22 | US4479724A | 1984-10-30 | Masataka Matsumoto; Toshio Murata |
| A water-resistant device for a watchcase of a diver's watch having a case body, a back and a glass. The device comprises an O-ring for sealing the watchcase, an annular leaf spring having an elasticity in the axial direction of the watchcase, and a bezel for the glass for compressing the leaf spring so as to urge the glass to the O-ring for maintaining watertightness of the watchcase. The O-ring and leaf spring are such that when the glass is moved by the difference between the pressure in the watchcase and atmospheric pressure, gases in the watchcase leak out through a gap formed by the movement of the glass. | ||||||
| 145 | Watchcase having a thin appearance when being worn | US400372 | 1982-07-21 | US4440505A | 1984-04-03 | Paul Gogniat |
| The watch case comprises, notably, a case band 1, a crystal 14 and a back 5 detachably mounted on the case band and a caging ring 6 assuring the positioning of a movement 22 in the case. The case band 1 has an upper opening 2 designed to be sealed by the crystal and a smaller-sized lower opening 3 defined by a projection 7 radially extending inward to its lower part. The caging ring 6 has an upper portion 10 and a lower portion 11 containing outer surfaces 12, 13, the dimensions of which correspond respectively to those of the upper opening 2 and lower opening 3 of the case band 1, the ring 6 being insertable in the latter through its upper opening before mounting of the crystal and placed so that its lower portion 11 is engaged in the lower opening 3 of the case band 1. The back 5 is held against the lower surface 8 of the projection 7 of the case band by means of set screws 9, tightening of which assures the locking of the caging ring 6 in the case. | ||||||

| 147 | Wrist-watch casing | US374689 | 1982-05-04 | US4397566A | 1983-08-09 | Marc Lederrey |
| The glass (1) of the wrist-watch casing carries the ornamental pieces of the casing visible face surrounding the watch dial (17). These pieces comprise a frame (2) of precious or semi-precious material or a very thin metallized layer (31) deposited under the glass (1). The frame (2) is glued in an indissoluble and resistant manner under glass (1) and a spacing frame (3) is similarly glued under frame (2). The collar (6) of tapped sockets (5) is caught and glued in lodgings (7) provided in the face of frame (3) which is glued to frame (2). The unit composed of these pieces (2, 3, 5) and the glass (1) are removably secured to the caseband (8) by means of screws (9) crossing the caseband and engaging sockets (5) fitting borings (19) of the caseband.Under the metallized layer (31) a single spacing frame (25) of base metal is necessary and sockets (5) are welded in lodgings (26) of that frame. | ||||||
| 148 | Glass mounting structure for watches | US289840 | 1981-08-04 | US4391534A | 1983-07-05 | Osamu Matsumura; Masataka Matsumoto |
| A structure for mounting a bezel in a watch case through a packing and for mounting a glass in the bezel through a packing.

| 149 | Watch case with interengaging flanged glass and flanged casing ring | US58157 | 1979-07-17 | US4322834A | 1982-03-30 | Walter Schaeren; Claude Ray |
| A watch case and means for fastening a viewing crystal to the upper opening of the watch case. The upper opening is provided with projections and the viewing crystal is provided with a flange for engaging the underside of the projections, on at least a part of its thickness. The viewing crystal is introduced freely into the upper opening and rests on a flexible element. Fastening is accomplished by pushing the piece of glass to compress the flexible element and engaging the flanges under the projections by rotation or movement in the case of the viewing crystal. The invention is particularly advantageous for monopiece cases. | ||||||

| 158 | Structure for sealing a watch crystal in a waterproof watch | US3676997D | 1971-08-16 | US3676997A | 1972-07-18 | FUJIMORI YOSHIAKI |
| A watch crystal is sealed into a watch by means of an annular gasket of a relatively hard material such as a synthetic resin or soft metal. The parts comprising the seal are so dimensioned that the crystal seats in the gasket in an interference fit and the gasket fits in the case body in an interference fit. Such gaskets, while providing an effective seal even when subjected to high pressure, have long life, and hold the crystal sufficiently strongly so that a bezel is not needed.
