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 Slim Steel Case

The watch features an ultra slim yet durable and corrosion resistant 316L stainless steel case with a diameter of 42mm and a thickness of only 8.6mm.

Swiss-Made Ronda Movement

The watch is powered by a reliable and accurate Swiss-Made Ronda 715 quartz movement with a battery life of 60-months. Ronda is one of the most respected makers of quartz movements and strictly adheres to an ISO 9001 quality control system to ensure that every movement meets the most rigorous standards.
