Swiss Tritium Illumination
How does Swiss tritium illumination technology work?
ArmourLite and Isobrite watches have tiny glass tubes that are filled with tritium gas and then hermetically sealed. The electrons of the gas continuously react with phosphorescent paint resulting in a radio luminescent light source that glows constantly. No external power source or charging-by-light is necessary to maintain the glow. The glow is completely self-powered.
What do the T25 and T100 designations mean?
The T25 and T100 designations refer to the combined amount of tritium gas that is hermetically sealed in the glass tubes in the watch. T25 watches have up to 25 mCI (millicuries) of tritium gas in the watch whereas T100 means there is up to 100 mCi of tritium gas in the watch.
What are the benefits of a T100 watch versus a T25 watch?
T100 represents the latest technology in tritium watches and makes seeing the time in the dark much easier on the eyes. Since the Isobrite T100 watches hold more tritium gas than T25 watches do, the higher volume of gas results in more electrical energy being created. More electrical energy results in much brighter visible illumination. When transitioning from a bright environment to a dark environment it takes the eyes time to adjust. With the increased visible brightness of T100, the transition is much easier on the eyes. Plus, as a person ages and the eyes don’t see as well, having T100 means the time can still be easily read in the dark.
Why do T100 watches last so much longer than T25 watches?
The Isobrite T100 watches contain approximately four times the amount of tritium gas as the T25 watches do. The higher volume of tritium gas results in a much brighter visible illumination combined with a much longer life span of illumination. The Isobrite T100 watches will have a life span that is approximately twice as long as the T25 watches. Plus, at 25 years the T100 watch will have the same visible illumination that the T25 watch started out with. By that point the tritium in a T25 watch would have become fully decayed and barely visible. On the other hand, the T100 watch will continue to glow for approximately 50 years.
Why isn’t the glow visible in bright lighting?
The tritium markers in the watch are constantly glowing. However, the glow is only visible to the eye as the ambient light starts to fade. The glow cannot compete with ambient light. As the level of ambient light decreases, the glow will become increasingly more visible.
Why do the tritium markers glow under ultraviolet light?
Shining ultraviolet light on the face of the watch is commonly done during sales presentations to show the colors of the tritium markers and simulate how the glow will appear in the dark. The science behind this is that ultraviolet light activates the phosphorescent paint in the tritium markers so that the glow becomes visible anytime and anywhere. It is important to note that ultraviolet light cannot differentiate between T100 and T25, or show how bright the watch will actually be in the dark. The intensity of visible brightness can only be seen in actuality by taking the watch into a dark environment.
