Vintage Pocket Watch Dead Beat Voltmeter Measuring 0-10 Volts and 0-100 Volts
This is a 1930/40s Vintage Pocket Watch Dead Beat Voltmeter Measuring 0-10 Volts and 0-100 Volts. I can't find a maker's mark.
In fair condition, there is some discolouration, loss of chrome, and surface scuffing commensurate with age and use. It has not been tested and I don't know whether or not it is working. It is being sold as a collectible, for display only.
The face is labelled with words written in French, English and German as follows:-
Volts
Aperiodique
Dead Beat
Knopf gedr. 10V (Press black button for the 10V scale)
The top scale measures 0-10 volts, and the bottom scale measures 0-100 volts.
Approximate Size: 5.5cm in diameter & 2.5 cm in depth.
This piece of vintage technology would have been carried around in a pocket as a handy tool for the engineer to make a quick (but not necessarily accurate) measurement. It now makes an interesting display item for a vintage engineering tool collector, or a tactile desk ornament.
