Abstract
In order to simplify the production of electronic watches, there is provided a family of standardized movements whose members can be housed within a variety of watch cases of different size and shape. All movements in the family are identical but for their mounting plates which differ in size, and in some instances also in shape, to render the movements receivable in differently-configured cases. The standardized movements in the family include batteries of different size which take advantage of the space made available by the plates of different size to afford optimum battery life.
