Here is a cool Nixie watch inspired by the Metro 2033 video game. It has a stainless steel case and Gorilla Glass display. The Metro 2033 45mm Nixie Watch has a rechargeable battery that lasts up to 3 months with the backlight off.
You can change animation type, time/year/calendar settings, and time format using the control button. The bad news? Something like this doesn’t come cheap.
