Abstract

1344393 Watches HAMILTON WATCH CO 17 Jan 1972 [29 April 1971] 2160/72 Heading G3T [Also in Division H1] A wristwatch has a non-magnetic case and an electrical timekeeper including a magnetic field responsive switch means operable from outside the case. The timekeeper has solid state electronic parts and electro-optical digital time display unit 20 forming a component 214 resiliently mounted on an intermediate plate 272 which is sealed to the front plate 270 of the watch to form a hermetically sealed compartment for the component 274. Batteries 276, 278 are mounted between the plate 272 and a detachable rear cover 274. A spring-loaded pushbutton 18 carries a magnet Figs. 10 to 12 (not shown) which operates a sealed magnetic reed contact unit 184 within the sealed compartment to complete a circuit which effects the display unit 20 which has its hour and minute figures illuminated for 1-25 seconds and then seconds figures only if the button is held pressed. Further contact units 198, 212 may be operated by a manually held magnet inserted in a slot 318, 320 but normally held in a strap recess. These units 198, 212 control circuits arranged to set the hour and minute settings respectively.
