🔸 LUMINESCENCE 🔸
Colloquially referred to as “lume,” luminescence is the glow given off by watch numerals, indices and hands that have been coated with a photoluminescent material (“lumed”). While early watches used radioactive radium to create lume, most modern watches use non-radioactive phosphorescent substances like strontium aluminate.
