Luminox micro-gas tubes

Every Luminox watch contains a tiny self-powered micro gas light tubes. These micro gas lights (borosilicate glass capsules) are installed in the hands, hour markers or the dial, and where applicable, into the bezels of our watches. These light tubes are safe to humans and the environment and are individually installed by hand into every watch. We call this self-powered function, the ALWAYS VISIBLE function. This advanced Swiss advancement allows the watches to ensure at-a-gland visibility, meaning the watches provide a constant glow 24/7 for up to 25 years.

While other watch brands use a phosphorescent paint on the markers that require an external light source to produce a “luminous effect”, Luminox does not.
