12:26 PM Tritium Technology in Isabel Marant Military Watches |
| Tritium Technology in Military Watches Tritium paint has been used on the hands
and numerals of watches since the 1930's. At first this technology was Top
Secret and restricted to use on military watches post2 by haiyan114.Tritium
paint on watches is a mixture of tritium and phospor. Tritium is naturally
radio-active and needs no external source of light or charge to work. Tritium
does not glow. As it decays, tritium emits beta radiation, which are a group of
excited electrons that in turn excite the electron in the phosphor atoms making
them emit photons, or light. As they return to their ground (non-excited) state,
the phosphor glows Beige

excited by UV light from the sun or other light sources. Thus, the tritium paint
relies on tritium radioactivity to make the phosphor glow in the dark, not any
charge from external light source.Tritium, has a half life of 12.3 years, a
half-life is simply the time it takes HALF of the tritium to decay. So as long
as there is enough tritium in the paint, the watch will glow for years.Due to
the toxicity of tritium based paint, a new technology was developed by
mb-microtec in Switzerland. This uses tritium gas sealed in vials. The principle
is the same but the tritium gas causes the coating on the vial to glow. The
levels of radiation are so small that they pose no risk to the wearer. This
technology has been used in the Traser H3, Luminox and Marathon military
watches. In recent years SRB of Canada have developed a similar system, this is
used by manufacturers such as Smith and Wesson, Rescuer and NITE. SRB tritium is
not as yet as well developed as the mb-microtec technology, only offering around
80 - 90% of the luminescence.The main advantage of tritium in military watches
is that there is no additional drain on the watch battery to power the night
light source, however these watches do have a drawback in that they can be
picked up at great distance by night vision equipment. It is therefore important
that these watches are covered during military operations at night.As the
technology has become cheaper it is finding its way into the civillian market.
Many sportsmen such as anglers and shooters wear tritium based watches with
Luminox and Traser being the most popular.Each year more and more manufacturers
are bringing new tritium watches onto the market Isabel Marant. As the tritium light
sources from SRB become more popular and combined with cheaper production in
China, it won't be long before we see tritium used in purely civillian
watches.Copyright 2006 Trevor Rowell
