Abstract
An improved electronic watch module easily manufactured and easily repaired has a housing lower half containing at least one watch integrated circuit electrically connected to a quartz crystal and a potential source. A switch in the housing lower half is used for operating the watch, i.e., for setting the time as well as providing minutes and seconds on demand rather than hours and minutes normally displayed. A housing upper half contains a liquid crystal display element and means for electrically interconnecting the display element and the at least one watch integrated circuit in the housing lower half. Releasable means fastens the housing lower and upper halves in assembled relationship. The upper and lower housing halves may be separately assembled and tested to insure proper operation prior to fastening them together.
