Key Product Features

Swiss T100 Tritium Illumination

Isobrite T100 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 for up to 50 years. No external power source or charging-by-light is necessary to maintain the glow. The glow is completely self-powered. T100 means there is up to 100 mCi of tritium gas in the watch whereas the majority of tritium-illuminated watches only have up to 25 mCi. The higher volume of gas results in much brighter visible illumination. T100 represents the latest technology in tritium watches and makes seeing the time in the dark much easier on the eyes. 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.

50 Years of Constant Illumination

The higher volume of tritium gas in the Isobrite T100 watches results in a much brighter visible illumination combined with a much longer life span of illumination. The illumination in the T100 watches will remain visible for approximately twice as long as T25 watches. Plus, at around 25 years the T100 watch will have the same visible illumination that a 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.

Scratch Resistant Sapphire Crystal

The watch face is protected by sapphire crystal, which is anti-reflective, scratch- resistant, and much harder than the standard mineral crystals found in most watches. Sapphire crystal provides exceptional clarity and is normally found in high-end luxury watches (i.e.: Rolex, Breitling, Omega).
