What is Tritium illumination?
Being able to tell the time with ease in
the dark is often overlooked in the
process of buying a watch.
This ability however, of always being able
to tell the time no matter what the
conditions, is always highly valued in the
day to day life of a watch – especially for
carp anglers. This is the reason therefore
why each and every Nite watch is fitted
with tritium illumination ­ the very best
form of watch illumination on the market.
The science behind Tritium illumination
Tritium, also known as super heavy hydrogen, emits electrons
through beta decay and when these electrons interact with a
phosphorous material, a fluorescent light is created that can last
up to 20 years.
When this Tritium powered illumination is sealed inside a
glass tube, it is known as a GTLS (Gaseous Tritium Light Source)
which is up to 100 times brighter over a long period than any
comparable technology.
To produce a GTLS vial, glass is lined with phosphorescent
material, then filled and pressurised by a machine with gaseous
tritium and sliced into segments by a laser beam to be sealed
Inside the vial, the electrons emitted by
the tritium gas excites the phosphor to give
off the cold continuous light. GTLS can be
created in different colours, generally green
is perceived by the human eye as the
brightest colour.
Key Features of Tritium
• Completely self­powered
• All vials are made in Switzerland
• Safe and reliable
• Provides a constant glow
throughout the night unlike
traditional illumination
• Lasts up to 20 years
• Available in a range of colours
Completely self­powered and providing a constant glow
throughout the night, Tritium illumination technology has been
trusted for decades by the emergency services, mountaineers,
deep­sea divers and military personnel due to its unwavering
reliability and performance in mission critical situations.
