  • Patent number: 10684648
    Abstract: There is disclosed herein a water tight submersible electronic device, such as a dive computer or a dive watch, comprising a case, a bezel, and glass through which a display can be viewed. The glass, case and bezel can all be different materials. The bezel is affixed to the case, in a permanent or removable manner, and has an opening for the glass and an electronic display. The electronic display is positioned under the glass and within the electronic device. For example, the glass is separated from and locked to the bezel by at least a locking ring, a shock absorber and/or a gasket. As such the glass can be free floating so that it and the bezel can deform under pressure without being damaged or causing damage to each other while maintaining a water tight connection.

The golfer(s) are responsible for maintaining the same pace on the course as the pace of the timer's moving clock hand across the easy to read face decal. The timer solves the problem of slow play and decreased course revenue due to slow play. The timer solves the expensive customization manufacturing problem since it may be mass produced, and after manufacturing the customized course decal may be created and applied. The Timer is easy to implement and use on any golf course.

    Abstract: A water-proof watch case and a method for manufacturing the same are disclosed. First, a design of a case and a bottom lid is decided, and a mold according to the design is fabricated accordingly. Next, a hard plastic material is injected into the mold to form the case and the bottom lid. Next, a soft plastic material is injected at an outer rim of the case to form at least one button, and a soft plastic material is injected at a conjunction between the case and the bottom lid to form a water-proof gasket. Finally, the hard and soft plastic materials are heated to adhere the button and the water-proof gasket to the outer rim of the case and the conjunction between the bottom lid and the case respectively.

  • Patent number: 7149153
    Abstract: In an electronic watch containing an electric battery assembly of large size, particularly a battery assembly including several batteries or accumulators (41, 42), the diameter of a removable cover (20) closing a large bottom opening of the back cover (14) of the watchcase is limited by the fact that the cover is provided with a bayonet fitting device having locking members (56) radially directed towards the interior. These locking members catch on a fixed support (22) having one or more housings for the battery assembly. They are arranged at the top of a substantially cylindrical annular portion (50) of the cover. A sealing gasket (52) is placed around this annular portion and compressed radially against a cylindrical surface (16) of the periphery of the opening in the back cover, which ensures water-resistance even if the bayonet fitting is not screwed all the way in. According to a variant, the cover can form the entire back cover of the case.

  • Patent number: 6200019
    Abstract: A device for locking the rotatable bezel of a watch and for rendering the winding button thereof watertight comprises a plastic washer connected to a flat surface of said button, coaxially thereto, so as to engage with circumferential knurling of the rotatable bezel, when the button is in a returned position, adjacent to the casing of the watch, in order to ensure the locking of the bezel. The device further comprises a seal which is carried by the button so as to be compressed between it and the casing when the button is in said returned position, in order to ensure watertightness of the button. Pressure means, movably supported by the casing, in a first position axially press the button holding it in said returned position and, in a second position, permits the outwards movement of the button to a rewinding and resetting position.

  • Patent number: 5696741
    Abstract: The invention concerns a timepiece, specifically a wrist watch, including a fluid resistant container (19) provided with a framework (20) of plastic material housing the horometric components. Such fluid resistant container (19) is closed by a crystal (22) and by a cell holder compartment lid (40) keyed to the framework and it is fitted out with a stem (26) on such framework rendered fluid resistant. The container is assembled and maintained in place in a metallic case (2) by snap securing means, in particular a bezel (18) which axially compresses a flange (20a) of the framework (20) and a toroidal seal (42) against the case (2). The case can thus be manufactured with loose tolerances. The assembled fluid resistant container and horological movement can be tested prior to its assembly in the case (2).

  • Patent number: 5610878
    Abstract: Desiccation capsule (20) for the interior (32) of an article comprising a first compartment (27) containing a desiccant (30). One wall (22) of the first compartment is perforated by a first opening (25) obturated by a semi-permeable membrane or a filter (23). The moisture on the interior of the article flows through this membrane and is absorbed by the desiccant.One of the walls (29) of the first compartment is transparent and permits the user of the article protected by the capsule to observe any change of colour or of appearance of the desiccant following the absorption of moisture. The capsule can then be withdrawn thanks to non-permanent fastening means (36) of screw or clip type and replaced by a new capsule. It is also possible to reuse the same capsule by heating the desiccant. A stopper (41) permits transport and stocking of the capsule prior to use.
