Yes, it is a crazy idea, but why not? We have oled, epaper and nixie watches but use super capacitors to power energy hungry led displays ?Designed by PeMi Technology, Ships from Slovakia

Absolutely unique, one of a kind, and world's first wristwatch powered with a Super-capacitor
Because when I was in school I learned that 1F is only theoretical capacity
Super capacitors are the new power source. Compared to batteries, they have different charging and power usage.
This is a new experimental board, with smaller capacity. I get great results.
Supercap powering MCU in sleep with consumption about 1uA. After I wake up, I calculate input voltage to compensate brightens. Remaining capacity is shown on bargraph.
About super cap power...
1.5F is about 10 minutes in highest brightness and 50 minutes in lowest. With auto voltage brightness is about 30 minutes. In standby about 5 days.
