Swiss T100 Tritium Illumination
Isobrite T100 watches have tiny glass tubes that are filled with up to 100 mCi of 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.
Scratch-Resistant Sapphire Crystal
The watch is protected by a scratch-resistant sapphire crystal with an anti-reflective coating. The strength and superior scratch resistance of sapphire crystal is the reason why it is used in nearly all high-end luxury watches.
Ultra Lightweight Case
The watch features an ultra lightweight and extremely durable carbon fiber reinforced case with a diameter of 39.5mm. The double-gasket push-in crown on the right side of the case is protected by two side shields.

Swiss-Made Ronda Movement
