NIXIE WATCH

 

 

Nixie tubes were originally used in different laboratory equipments or military devices. In the last decade these tubes got a new life turning into nice clocks. As desktop clocks are more common than wristwatches then the idea came to design one. This design uses 4 pieces of RFT Z5900M nixie tubes manufactured in the 1970s.
