How to charge the lume
Radiant uses Swiss Super-LumiNova BGW9 on hands and hour markers for legibility in the dark. It charges from light.
- Expose the dial to a bright light source, ideally daylight or a strong indoor light.
- 10-30 minutes in direct sunlight or 2-3 minutes under a flashlight will provide a long-lasting glow.
