Completed Nixie Watch
First Prototype (Handmade Bezel)
Personal "Production" Unit (Note engraved Russian Cyrillic). I wear this a few times a week.
This is, to the best of my knowledge, the smallest Nixie watch built. A few people have built two and four tube
models, but I didn't think that they were "practical"...
The 4-tube watch sold for $500, and 25 were built. The two-tube watch was never taken beyond "prototype".
The guy who built it is, however, close to building a "production" model.
