A wristwatch movement has a back cover formed with a battery replacement hole, and a base plate formed with a battery compartment in a substantially axial alignment with the battery replacement hole. An actuating lever has one end selectively engageable with a setting lever engaging with a winding stem extending through a radial bore of the base plate, and another end formed with a handling portion extending toward the battery compartment such that the handling portion can be manipulated through the battery replacement hole to cause the one end of the setting lever to disengage from the winding stem, to allow the winding stem to be pulled out of the radial bore.
An electronic watch of relatively few parts and consequent inexpensive construction employing a liquid crystal display (LCD), an integrated circuit chip and a watch battery. The watch is electrically dormant until activated by means of a pull tab. Adjustments are made through holes in the watch case.
A timepiece movement has a case in which are mounted a driving motor, a gear train driven by the motor, a printed circuit board having a driving circuit for driving the motor, and a battery accommodating portion for replaceably receiving a battery. A pair of battery contacts for electrically connecting the battery to the printed circuit board are provided on the outer surface of the case. One end of each of the battery contacts extends through an opening in the case to make elastic contact with the battery, and the other end of each of the battery contacts extends through another opening in the case to make elastic contact with the printed circuit board.
A battery housing comprises a hole entirely piercing the watch base plate and a cover closing the hole. Such cover is secured to the hole by fastening means which comprises in one form a flange projecting into the hole. In the cover moreover a tongue is raised which serves as a mechanical support to one face of the battery and, via a printed circuit arranged between the cover and the battery, the electrical contacting of the battery electrode forming part of said face.
An LED flashlight construction is formed from molded plastic housing members joined to provide a tubular section connected to a battery chamber capable of holding one or more disc batteries capable of providing adequate voltage for operating a light emitting diode positioned at the distal end of the tubular section. A conductive metal pocket clip may be elastically deformed for closure of the circuit to provide power to the light emitting diode.
