Title: Energy cell for watch

Abstract: An energy cell for a wrist watch comprises a silver-zinc button-type cell having a bottom can for the cathode material and a top cap for the anode material mounted thereover with separating means between the anode and cathode materials. The cathode material in the bottom can of the first embodiment is divalent silver oxide mixed with sulfur. This cathode material provides a lower voltage similar to that of the conventional monovalent silver oxide material but has a higher cell capacity. A second embodiment of the invention comprises a cathode material of silver sulfide mixed with divalent silver oxide. This embodiment also retains the higher capacity of the divalent silver oxide while supplying a lower voltage similar to that of the monovalent silver oxide. The anode material in both embodiments is a predetermined zinc amalgam.
