Abstract: The dial (3) is secured onto a lower element (10) of the case, preferably the casing ring. The lower element (10) includes at least two through passages (12) each having a first part (13) forming an orifice (14) on the dial (3) side separated from a second part (17) on the opposite side, by a neck portion (15), the whole of the first part and at least a portion of the second part of said passages (12) being filled with an adhesive material (19) having a strong power of adhesion to at least the material forming the lower face of the dial (3).
Abstract: The invention relates to a timepiece having a body or frame upon which an added element may be held, in a detachable manner. The invention also relates to a method of assembling this element on said body or frame.This timepiece is characterized in that the fixation means of the element added to the body or frame are formed by at least one rotating bolt (10) which is anchored permanently in the material itself of the body or frame (2) and is axially immobilized by said material.
Abstract: The timepiece comprises a base part (1) of plastic material, at least one element (2) secured to said base part and securing means for said element onto said base part which comprise a stud (34) driven at one of its ends (40) into a through hole (32) in the base part (1). The other end (12) of the stud (34) is fitted into a hole (10) of the element (2) and is upset against the latter so as to form a rivet. Finally the base part (1) is fashioned in a manner to permit access to the driven end (40) of the stud with a tool (A) furnishing a rigid support under the stud during the riveting operation on the other end (12) of the latter.
Abstract: The watch (1) in accordance with the invention comprises positioning means for the movement in the case. The positioning means comprise two blind holes (30) arranged in the case (6) and two centering elements (32), these latter having a first part driven into the blind holes and a second part (36) projecting from the case and cooperating with openings (38) provided in the movement.
Abstract: The watch case comprises a middle cum bezel unit (14,16), a glass (18) secured to the unit and a bell-shaped cap (20). The glass (18) is formed with a heel (28) extending radially towards the periphery of the case. The glass (18) further defines with the bezel-forming portion (16) of the unit a groove (30) by means of which the cap (20) is secured and positioned.
Abstract: A watch with a case, a glass, a case band, a back, a movement, hands, a dial and means for positioning the dial in the watch.The positioning means have a first part fixed and positioned axially, radially and angularly and a second part and associated with the periphery of the dial which cooperates with the stop of the first part to position the dial axially and angularly while still permitting radial deformation.
Abstract: A clock includes a dial, a transparent cover plate spaced apart from the dial at a certain interval to define a space between the back face of the cover plate and the front face of the dial, and hands disposed in the space and driven to move relative to the dial to indicate time. Spacers are disposed on the visible portion of the front face of the dial and protrude against the back face of the cover plate such that the spacers are contactable with the back face of the cover plate upon deformation of the dial and the cover plate to maintain a sufficient interval of the space to allow face movement of the hands.
Abstract: A crown switch actuator in a solid state analog wristwatch rotates in either direction and is movable axially. The actuator stem has a flat portion which rotatably operates a rocker contact spring against contact pads on a printed circuit board to alternately close first and second switches. The rocker contact spring also detents the switch actuator in one of two axial positions and retains the crown actuator in the watch case. Third and fourth switches are alternately closed by axial movement of the crown actuator stem. In a first detented axial position, the third switch is closed. In a second detected axial position, the third and fourth switches are open. In a third axial position, the fourth switch is closed. An extension arm on the detent rocker contact spring provides for releasing the crown actuator from the watch case.

Abstract: A clock which is intended for use in soda fountains, restaurants, bars and other places of business as an advertising display, and which may be illuminated. The clock comprises a rectangular-shaped rigid frame, a translucent thin plastic panel constituting a clock face which is mounted in the frame and which extends across the area circumscribed by the frame, the thin panel being held in place by integral lugs which fit into slots in the frame, and a transparent plastic cover mounted on the frame in front of the clock face. In one embodiment the drive motor for the clock is mounted on the rear side of the plastic panel. In a second embodiment the drive motor, together with an illumination source for the translucent panel, are mounted in a housing which is supported on the rear side of the frame behind the thin plastic panel.
Abstract: The clock comprises a usual clockwork, as well as a first annular component provided with a ring of pin-like projections parallel to one another; a second component which is also annular and can be coupled with the first component and provided with a ring of openings which can be aligned with and passed through by the pin-like projections and located on an inner flange thereof; a substantially flat dial to rest on the inner flange and provided with a ring of openings which can be aligned with those of the second component and passed through the pin-like projections thus forming the time references; and a third transparent component provided with contour side insertable in the second component.
Abstract: The assembly includes a timepiece case having an undercut portion forming a maneuvering recess for a dial plate which is oversized in one dimension relative to an access opening in the case. The maneuvering recess allows a dial plate larger in one dimension than the access opening to be inserted into the case. A larger, more aesthetically-pleasing dial plate can thereby be employed while retaining an appearance of thinness for the timepiece case.
Abstract: A watch movement having a frame comprising a bottom plate with a peripheral rim portion, a dial secured to said rim portion, and a holding plate disposed between the bottom plate and the dial is described, wherein the holding plate is made of a thin sheet of material and includes one or more positioning elements cooperating with the bottom plate and one or more raised support tongues cooperating with the dial.
Abstract: A novel construction is provided for a timepiece of the type having a shaped (or non-circular) case and crystal in conjunction with a circular caseback. The construction typically includes a shaped case having a shaped recess in one side and a circular aperture in the other side with a central cylindrical bore therebetween. The bottom of the shaped recess is formed by the intersection of the recess and cylindrical bore and is in the form of an annular shoulder having a non-circular outer periphery and a circular inner periphery providing a central opening in the recess bottom. Supported in the cylindrical bore and visible through the central opening in the bottom of the recess is a circular dial plate.
Abstract: A solar battery powered electronic timepiece of the type wherein a watch glass and a base plate supporting a solar battery are secured in an annular recess in a watch case. The base plate is positioned on a bottom surface of the recess and secured in position by a resilient packing which is preferably made from a resin material. The packing extends around the base plate and has a portion which overlines the outer periphery of the base plate and on which is positioned the watch glass. Another portion of the packing extends between the outer periphery of the watch glass and a side wall of the recess to secure the watch glass in position. A structure of this type is particularly suitable for securing a base plate of a material such as epoxy resin to which fastening legs cannot easily be attached.
