These watches really DO illuminate in the dark !

Traser H3 are top quality Swiss watches, extremely robust and reliable. Chosen by the worlds elite military including the SAS & SBS for their build quality and illumination performance, traser H3 watches have proven themselves on active duty throughout the world

Trigalight Illumination - All traser H3 watches feature trigalight (tritium gaseous light) illumination technology. This highly specialised technology was developed by mb-microtec where a guaranteed light source was needed for safe operations in all hazardous environments and conditions.

Trigalight are tiny glass vials that are laser sealed, internally coated with phosphorescent material and filled with a minute amount of tritium gas. Electrons emitted from the gas excite the phosphor to create the permanent light. They do not require any external power source or require recharging in order to glow continuously for up to 20 years.

Trigalights can be manufactured in a variety of colours by using different phosphorescent material. Green is the preferred colour because it is perceived to be the brightest by the human eye but we also use Orange, Yellow and Blue. Blue is primarily used in watches for underwater use as it remains visible to the human eye for longer than any other colour.

		Comparing trigalight illumination and SuperLumiNova If the luminous markings on a watch are reasonably sized and arranged, the readability in the dark is primarily determined by their total light emitted. In order to assess the relative merits, the light intensity of two dials with identical markings were measured and compared. One dial featured trigalight technology ( traser H3-watch ) and the other SuperLumiNova

The results, with the light intensity expressed in the unit "nanocandela" (ncd) are given below.

after (in darkness)	0 min	5 min	1 hour	8 hours
traser (in nanocandela)	6000	6000	6000	6000
LumiNova (in nanocandela)	10000	6000	400	30

Traser 6000 ncd*		Super Lumi Nova 400 ncd*
