The Chronotronix V400 is a cleverly designed Clock, which combines vacuum tubes and state of the art electronics. The base is made of cherry wood and the tubes themselves are set on black anodized aluminum, which gives it a futuristic look. The clock even has inbuilt batteries to keep it going, when no electricity is available. The coolness factor of this clock is off the scale. The only disappointment is the price though – a mind numbing $385. Still, it’s a very interesting and desirable combination of art and technology.

The CHRONOTRONIX V400 NIXIE CLOCK uses a state of the art circuitry. Time is kept by an ultra precise real time clock. It’s accurate to within 0.0003s per minute. The clock is not multiplexed, but the Nixie tubes are driven directly.TUBES
These tubes are biquinary ones from the ZM1032 and B-5025 series. They show a digit height of 15.5mm (0.61″). Long life and stable operation are benefits of these tubes. The clock has a Cathode Poisoning Prevention for an increased life expectancy.
