Definitions

  • a pin 10 on back cover 9 of the watch and a support pin 11 fixed to rotation plate 7 serve for mounting spring 12 which biases plate 7 for rotation opposite to the direction of the arrow.
  • pin 6 normally rests on the deepest portion of the groove 8 as the result of which connection between battery 1 and timedisplay means 5 is normally broken.
  • said plate has an arcuate groove therein, said groove tapering in depth from one end to the other, and said switch means having a first pin movable in a direction perpendicular to said plate and being biased to make continuous contact at its outer end with the'bottom of said groove, whereby rotation of said plate in one sense or the other causes said first pin of said switch to move axially in one direction or the other and to make or break contact in said switch to activate or deactivate said time-display means.
