These days one can find many nixe clocks on the internet which look all nice and pretty. But to me the small watches seal the deal of what one can built out of 2 nixies. I guess it would be an interesting project in regard to the fact that it combains the creation of a high voltage power supply and a microcontroller under the pressure to make it all fit in a small watch. And even though i prefere the round shape, https://www.facebook.com/nixiewatch shows that it is also possible to power a tube via small solar pannel.
