In the past few months, we have covered a bunch of awesome Nixie Tube clocks. The Watch Mark 2 is also worth a look. It is a handmade Nixie wristwatch with IV-9 numitron tubes. It has an an aluminum alloy body and protective glass.
The watch shows the time when you press the appropriate buttons and the date when you press and hold. A convenient motion sensor is also available, so you can look up the time with less effort.
