ABSTRACT:
Electronic watch module is constructed of a spacer block, a substrate on the spacer block carrying electronic components thereon, and a cover over some of the electronic components. Basic rate control of the electronic watches is provided by a crystal which is mounted in a can. An opening in the spacer block receives the crystal can, and deflectable fingers on the spacer block restrain the crystal can in place.
