Description
This digital display clock was a novelty when the Swis Longines Company made it in the early 1960s. The orange numbers are produced by 'nixie' tubes based on neon lamps. A control logic makes the orange discharge form around one of the 10 display electrodes designed to show the digits one to nine.
