Been meaning to post this - Superluminova ages, so if you want your old watch to glow again there are a few places known to do good work:
- Motor City Watch Works (MCWW) - also does Cerakote and other cool mods
- Do it yourself with this kit from NoctiLumina for $30
- Kent Parks at Everest Watchworks has an excellent rep too.
Not sure if Pyrolume or Lum-Tec do this as a service. I was unable to find mention of it.
