@teajaygrey @NanoRaptor Woz bought the Nixie watch after he saw my friend Ken wearing one. So did I. Ken and I were both volunteers at the Computer History Museum at the time, on the PDP-1 Restoration Project.
I only wear mine on special occastions.
@brouhaha yeah, tubes can be fragile. I have a DAP with vacuum tubes that I use sparingly because I don't want to deal with it breaking and having to repair or replace it.
Alex, the Director at the made.org had a four digit/tube Nixie clock at his house, but I imagine the wrist watch variants are more prone to wear and tear than something stationary.
