Abstract
Abstract Electronic watch movement is principally electronics mounted upon a substrate. The substrate is mounted with respect to the watchcase so that it can laterally shift in response to lateral shock. Springs are mounted on the substrate and resiliently center the substrate. At least one of these springs is electrically connected to the circuitry on the substrate and is contactable by an externally actuatable push-button so that external action on the watchcase can result in electrical changes in the electronic circuit of the watch movement.
