I noticed how hard it was to tell time in the darkness of the night with my existing analog watch. An analogue watch with SuperLumiNova(tm) will be usable all night from a 10 second blast with a good torch. Source: regularly do this.

  10 second blast with an oxy-acetylene torch and it'll be illuminated for the rest of its useful life.
