With Movement Ring Details Patents (Class 368/299)
  • Patent number: 9535403
    Abstract: A watch is delimited by a case formed of a back cover and of a middle part. A timepiece movement is disposed in a casing ring housed inside the watch case. The watch also includes a dial disposed on top of the casing ring and held by a fixing ring. The fixing ring has an S-shaped cross-section. An upper branch of the fixing ring is supported on the dial and a lower branch of the fixing ring is supported on the casing ring. The lower branch of the fixing ring is clamped between the middle part and the casing ring, so as to grip the dial between the upper branch of the fixing ring and the casing ring.

  • Patent number: 7307921
    Abstract: A watch design that has a movable case that keeps the face of the watch visible regardless of the position of the wrist. In this way, a user can quickly see the watch face in the proper orientation so that the time can be quickly and correctly determined. There are several ways to accomplish this. The case can be mounted on a turntable that rotates on the y-axis. A frame containing the watch mechanism and display is hinged on said turntable and rotated vertically upon the x-axis described by the hinge-mounted frame mounted on said frame. Another embodiment uses a gimbaled point on which the face is free to rotate, much like a compass. In this embodiment, the watch case is weighted to that the face always moves to a readable position. Finally, the watch may include displays mounted in the link of a watchband.

  • Patent number: 6616329
    Abstract: In a structure in which a rotating bezel is mounted on a case body, the present invention provides the structure which permits the rotating bezel to be mounted and removed without difficulty even if a brittle material and a deformation difficult material is used in the rotating bezel. When the rotating bezel 25 is pushed downward, the lower end of the engaging rib 25a of the rotating bezel 25 is abutted against the upper end of the holding rib 21d of a glass fixing ring 21 and stress is applied thereby so that the elastically deformable section 21b of the glass fixing ring 21 is elastically deformed inward, that is, toward the side where a clearance is formed. As a result, the engaging rib 25a goes over the holding rib 21d and the rotating bezel 25 is kept in a held state as shown in the figure.

  • Patent number: 4831607
    Abstract: The case is essentially made up of a hollow middle cum glass unit (1), consisting of an integral glass pressing, and of a metal back (10) closing off a cavity (5) defined by the inside surface of the hollow unit, the cavity providing a housing for a movement.In the cavity is mounted a metal ring (15) having a centering flange (16) bearing against the middle portion of the unit. In the space between the ring and the middle portion are inserted a deformable rubber gasket (19) and a metal annulus (18) whose radially outer surface is formed with a bevel (18') in the region nearest the gasket.Screws (20) secure the back (10) to the ring (15) and press it against the annulus (18). On being driven home, the screws wedge the bevel (18') between the gasket and the ring thereby to apply a radial force on the gasket . This force presses the gasket against the middle portion of the unit and prevents it from moving out of the cavity.
