  • ABSTRACT An internal capsule constituted by a vessel made of a soft Foreign Application Priority Data Feb. 17, 1969 plastic material and by the watchglass is kept closed by an external capsule constituted by two metallic pieces fixed onto .58/ R 04 37 0 one another by screws. These pieces press the glass axially on 53 53 33 90 the upper edge of the lateral portion of the plastic vessel so as Int. Cl.
  • the glass has a cup shape. It is made integral with a peripheral sidewall extending in an axial direction and the plastic vessel is inserted into this glass wall so as to tightly engage the same.
  • the tight closure of the internal capsule is accordingly due to the radial pressure exerted on a portion of the plastic vessel, i.e., to a pressure exerted in a direction perpendicular to the watchcase axis.
  • the tightness of the internal capsule thus depends the more on the manufacturing tolerances of the components of the external capsule, of the plastic vessel and of the glass as the vessel portion engaging the glass is thin.
  • the external capsule thus holds the two components of the internal capsule in a predetermined position with respect to each other, it determines the extent of the axial pressure of the glass on the vessel. Accordingly the flat surfaces of said peripheral flanges need only be located on the two pieces of the external capsule in such positions with respect to the portions of said pieces which engage the glass and the vessel bottom, respectively, that a tight seal will be ensured between the glass and the vessel while preventing, however, the vessel and the glass from being subjected to an excessive stress.
  • a continuous rim can, for that purpose, be formed integrally with the lateral portion of the plastic vessel so as to project axially upwards from the upper edge thereof, said rim having a rounded cross section and engaging the peripheral portion of the inner side surface of the glass.
  • Still another object of the invention is to enable keeping usual margins in the manufacture of all the watchcase parts.
  • a peripheral rim can therefore be formed integrally with the lateral portion of the plastic vessel so as to project radially outwards from the outer side surface thereof, said rim extending all round said lateral portion and having a rounded cross section and said lateral portion engaging the peripheral flange of one of the two pieces constituting the external capsule by means of said rim.
  • FIGS. 2, 3 and 4 are sectional views along lines IIII, III- III, and IV-IV, respectively, of FIG. I, and
  • FIG. 5 is a sectional view similar to that of FIG. 3 but showing the second embodiment.
  • the watchcase represented in FIGS. 1-4 has a rectangular shape. It is adapted for receiving a circular watch movement I carrying a dial 2 which extends radially outwards beyond the edge of the watch movement 1 and has a shape similar to that of the watchcase.
  • the movement 1 is inserted in a vessel 3 comprising a bottom portion covering the bridge side of the watch movement and a lateral portion extending upright form the periphery of the bottom portion.
  • the inner side surface of the lateral portion of vessel 3 has a contour adapted to that of movement 1 so as to encompass the edge of this movement.
  • the vessel 3 is made out of a soft plastic material so that rim 5 engages the glass flange 7 while forming a tight seal between vessel 3 and glass 6 as soon as the latter is pressed axially to some extent on rim 5.
  • Vessel 3 carries a tube 8 for the passage of the usual winding and hand-setting stem of the watch movement.
  • Tube 8 is tightly fixed to vessel 3.
  • the tightness of the stem passage itself through tube 8 is ensured in the usual manner by the winding and hand-setting crown 9 which carries a female stem part (not shown) adapted for being clutched to the male part 10 of the stem portion carried by movement I.
  • Vessel 3 can easily be manufactured, for instance by molding an elastomer, such as perbunam, buna, rubber, neoprene, silicone, viton, genthane, ethylene-propylene, polyacrylate, hypalon or vulcolan. Since most of these substances are soft, vessel 3 will provide for a resilient suspension of the movement 1 damping the impacts to which the external capsule may be subjected in use. In view of improving that suspension, two peripheral rims 18, 19 are formed integrally with the lateral portion of the vessel 3 so as to project radially outwards from the outer side surface thereof. Rim 19 is on the same level as the part 20 of the inner side surface of the lateral portion of vessel 3 extending above ring 4 and engaging a bearing surface of movement 1. Rim 19 can easily be given such sizes when molding vessel 3 that part 20 of the inner side surface of the lateral portion of vessel 3 bears against the corresponding bearing surface of movement 1 strongly enough in order to hold movement 1 axially in place within vessel 3.
  • Cutouts 11b, 12b are provided in pieces 11 and 12 for the passage of tube 8 and piece 11 carries bars 21 for attaching the wristband to the external capsule of the watchcase. Water infiltration between piece 11 and vessel 3 can be avoided by providing the passage for tube 8 fully within piece 12. In such a modification, the glass would cause the outer part of the lateral portion of the vessel to be pressed on the part of surface 1 la projecting radially inwards from piece 12.
  • tube 8 is secured to vessel 3 by gluing.
  • Glues compatible with the material of the vessel can easily be found on the market. They have the property to adhere to the metal and the material of the vessel to such an extent that it is no more possible to remove the tube from the vessel without tearing away some portion of the latter.
  • the watchcase of the embodiment described comprises a usual glass made out of an organic plastic material. Without modifying the technique resorted to for ensuring the tight closure of the internal capsule as well as for securing the watch movement therein, it would also be possible to provide the watchcase with a hardened mineral glass or a sapphire as shown in the second embodiment represented in FIG. 5. Since machining operations on hardened mineral glasses as well as on sapphires have to be avoided as far as possible, the glass 6a of the second embodiment is constituted by a flat plate having the desired contour. In this embodiment, the peripheral portion of the glass inner side surface is permitted to lie on the vessel upper edge for sealing the internal capsule by providing the plastic vessel 3 with a continuous rim 5a higher than in the first embodiment. The peripheral portion of dial 2a is bent upwards as shown at 22 in order to hide rim 5a.
  • the visible face of the watch can I be given a plurality of different shapes (circular, oval, square, rectangular, triangular, polygonal, etc.) without modifying the substantial manufacturing operations of piece 12c of the external capsule of the watchcase.
  • piece can indeed be made with a continuous central wcb. According to the desired shape of the visible dial part, a corresponding opening is then stamped in this web. Finally, the inner edge of piece 12c need only be rounded to obtain the bezel 14a shown in the drawing.
  • the latter can compensate for the usual differences due to the manufacturing tolerances of the metallic pieces constituting the external capsule of the watchcase.
  • a watertight watchcase for Wristwatches comprising, in combination, a vessel made out of a soft plastic material and having a bottom portion and a lateral portion extending upright from the periphery of the bottom portion and having an upper edge, a watchglass having an inner and an outer side surface, the glass inner side surface having a peripheral portion lying on the upper edge of the lateral portion of the plastic vessel, an external bottom piece engaging the bottom portion of the plastic vessel and having a peripheral flange with a flat surface surrounding said vessel, an external bezel engaging a peripheral portion of the outer side surface of the glass and having a peripheral flange with a flat lower surface surrounding said vessel, and removable securing means firmly holding said flat upper surface of the bottom piece and said flat lower surface of the bezel in abutting engagement with each other, thereby causing the glass to be pressed on the vessel to a predetermined extent, said plastic vessel and said glass constituting an internaltight capsule for the watch movement, and said bottom piece and said bezel constituting an external capsule encompassing said internal
  • a watertight watchcase according to claim 1, the contours of the inner side surface and of the outer side of said lateral portion of the plastic vessel being adapted in such manner to that of the watch movement to be received by said internal capsule and to that of said peripheral flanges, respectively, as to cause said lateral portion of the plastic vessel to be pressed in a direction perpendicular to the watchcase axis between the watch movement and at least one of said peripheral flanges thus causing a clamping action to be exerted on the watch movement and holding this movement transversely and axially in a predetermined position within said internal capsule.
  • a watertight watchcase in combination, a vessel made out of a soft plastic material and having a bottom portion and a lateral portion extending upright from the periphery of the bottom portion and having an upper edge, a watchglass having an inner and an outer surface, the glass inner side surface having a peripheral portion lying on the upper edge of the lateral portion of the plastic vessel, an external bottom piece engaging the bottom portion of the plastic vessel and having a peripheral flange with a flat upper surface surrounding said vessel, an external bezel engaging a peripheral portion of the outer side surface of the glass and having a peripheral flange with a flat lower surface surrounding said vessel, removable securing means firmly holding said flat upper surface of the bottom piece and said flat lower surface of the bezel in abutting engagement with each other, thereby causing the glass to be pressed on the vessel to a predetermined extent, said plastic vessel and said glass constituting an internal tight capsule for the watch movement, and said bottom piece and said bezel constituting an external capsule encompassing said internal capsule and ensuring the closure thereof by holding said vessel and
