Abstract

Electric watch has its battery held in the battery block in the watch module by means of a retainer spring which resiliently engages the batteries to urge them into proper installed position. Fingers on the spring resiliently engage in the spacer block to provide the spring retaining force. The fingers can be manually disengaged from the back of the spacer block for retainer spring and battery removal.
