Tritium Illumination

All Nite watches feature a rare illumination technology called GTLS (Gaseous Tritium Light Source). This highly specialised technology was, until recently only ever used in advanced military hardware or pioneering safety equipment where a guaranteed light source was needed for safe operations in all hazardous environments and conditions.

Exactly the same technology has now been adopted by Nite in a range of advanced sports watches that offer the same standards of reliability and durability to non professional personel.

Every Nite watch is fitted with a minimum of fifteen GTLS lamps, giving you a dial that can be read quickly and easily in all light levels.

How does a GTLS work?

Electrons emitted from the tritium gas excite the phosphor coating inside each GTLS lamp to produce a continuous light that will typically last between 10 and 20 years.

How do I switch the illumination on?

You don’t need to. The chemical reaction inside each GTLS is permanently working. As soon as the light levels drop the lamps become clearly visible.
