Pulsar Watch Module Tester

This appears to be a Pulsar watch module tester that was designed to quickly test the watch functions without needing to add new batteries and close up the back. All that was required was to place the watch, with the back cover off (and no batteries) on the tester so that the two test probes hit the location where the batteries would be located. The tester used 4 D batteries, used in parallel so you still only get 1.5 volts, and turned on with a switch on the back of the tester. A jeweler who used this in the 70’s said it would save a lot of time checking out the watch -- not to mention that there was never a question regarding if the batteries were good or if good contact was being made.
