Abstract: The invention concerns a miniature pushbutton for a timepiece and includes head portion (1) associated with a socket (2) force fitted into a caseband (15). Considered in isolation it constitutes a dormant corrector since it lacks a return spring thus permitting a considerable reduction in its dimensions. The head portion including stem is fashioned in a manner to permit assembly and disassembly from the timepiece exterior thus facilitating these operations. A retention system is provided which prevents inadvertent separation of the head-stem portion from the socket. Such pushbutton may be advantageously employed in extra thin timepieces.

Abstract: A recessed push button in the back of an electronic watch is sealed and returned to its normal position by a resilient O-ring gasket, and retained in a recessed opening in the watch case by a spring retaining clip. The clip has a keyhole slot transversely slidable around a groove in the push button stem, with a retaining tab locking the clip in position. A first conductive member maintains contact with the clip, holding it in position, and a second conductive member is spaced from and contacted by the clip when the push button is depressed.

Abstract: This disclosure relates to a watch case which includes a case body housing a movable element actuated by a slidably mounted pushbutton for effecting movement of the movable element through a rod connected to the pushbutton, the rod having a portion which transfers the sliding movement of the pushbutton to the movable element, and guide means in the form of grooves, bores or guide surfaces for guiding the movement of the rod relative to the case body during the movement of the rod under the influence of the sliding movement of the pushbutton.

Abstract: A control member such as a push button or winder for a thin water-tight watch has a tube fitted to the watch case, and a control rod movable in the tube by a manually movable head fixed to the rod. Surrounding the tube axis is a sealing O-ring making sealing contact with and around a surface of the tube. The ring compressed axially of the tube is disposed between the head and tube in a housing defined in part by first and second faces on the head. The first face is annular in a plane at right-angles to the tube axis and the second face is cylindrical centered on the tube axis and spaced radially of the tube from the ring.

Abstract: A setting device for analog-display motor vehicle clocks having an operating knob made of injection-molded plastic, which knob is turnable and elastically displaceable axially within a central passage opening in the cover glass against the action of a spring, the knob being provided with a driver for engagement into the pointer shaft. The driver, and at least two guide pins which are provided with grappling hooks, are formed of plastic integrally in one-piece with the operating knob. The guide pins are dimensioned in such a manner with respect to their material and length that the operating knob is inserted from the front side of the cover glass through the passage opening with deflection of the hooks with the guide pins and is secured against falling out after the hooks engage through and return into their original unstressed position.

Abstract: A water resisting crown structure for electronic wristwatches comprises a guide pipe secured to a watch case, a crown stem slidably engaged in the guide pipe, and a crown locked to the guide pipe by a thread engagement. The guide pipe has an outwardly extending large diameter portion having a thread thereon. The crown stem is connected to a correcting means such as hands and calendar correcting means of the electronic wristwatch and has a non-circular flange on an outer end portion. The crown has an inner cylindrical portion and an outer cylindrical portion which are coaxial with the guide pipe and crown stem. The inner cylindrical portion has a non-circular inner wall engaged with the non-circular flange of the crown stem. The outer cylindrical portion has an inner thread adapted to be engaged with the thread of the guide pipe for locking the crown. A packing is provided in the annular space between the outer cylindrical portion and the inner cylindrical portion of the crown.

Abstract: The setting mechanism of a watch includes a winding stem and a clutch wheel which can be moved selectively either rotationally or axially by said winding stem for control of one or more setting levers or wheels. The setting levers or wheels are disposed on the opposite side of said winding stem from the dial plate of the watch, thereby making it possible to center the winding stem in the thickness direction of the watch and to reduce the over-all thickness of the watch.

Abstract: In order to simplify the production of electronic watches, there is provided a family of standardized movements whose members can be housed within a variety of watch cases of different size and shape. All movements in the family are identical but for their mounting plates which differ in size, and in some instances also in shape, to render the movements receivable in differently-configured cases. The standardized movements in the family include batteries of different size which take advantage of the space made available by the plates of different size to afford optimum battery life.
