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 many decades. 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 47mm. The double-gasket push-in crown on the right side of the case is protected by two side shields. For keeping track of elapsed dive time, the case has a unidirectional ratcheting diver bezel with a tritium elapsed minute marker.
Swiss-Made Ronda Movement
The watch is powered by a reliable and accurate Swiss-Made Ronda 5040.D quartz chronograph movement with 13 jewels and gold plating. The chronograph function of the movement has a center stop second (1/1 second), a 1/10 second counter up to 30 minutes, a 30 minute counter, a 10 hour counter, and add and split functions. The movement also features a power saving mechanism that is activated by pulling out the crown and reduces battery consumption by approximately 70%. 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.
