Review on Energizer 387S Button Cell Silver Oxide Watch Battery Pack - 5 Batteries for Superior Power by Sally Wiesner

The battery is easy to replace, but then the clock won't work, at least mine. It was my father's high school graduation gift in the spring of 1965. Part of my strategy was to order a battery that will probably last a lifetime (what's left of it), paying for what I saved by buying the watch brought somewhere. for repair. You may have better luck, but maybe not if you haven't worn it in a while. Does anyone know a watchmaker familiar with the Accutron Astronaut in Denver?
