Pocket watch meters were a common piece of test equipment in the 1920s; at a time when batteries and electrical devices were just beginning to come into the hands of the average person, there was a need for means to test and repair all of these new devices. A pocket watch meter was called such because it shared the size and shape of a common pocketwatch, many such meters used surplus watch cases as the basis for their construction. This Eveready pocket watch meter is fairly representative of how such meters were constructed. A hole and stud at the base of the meter act as one terminal, with the other terminal being attached where the winding stem would be located on a pocket watch. Measurements would be taken by touching the stud on the base of the meter against one of the terminals being tested while touching a loop of wire to the other terminal and the socket at the winding stem. The example shown here still includes it's original testing lead, which plugs into the hole at the top of the meter where the winding stem socket is located.
