This 47mm black and gray accented Swiss Made watch features 21 ultra bright T100 tritium markers that will glow for many decades. A combination of green and orange tritium markers makes it incredibly easy to tell the time in any lighting environment. Plus, the uniquely flat shape of the tritium markers around the dial increase the visible surface area making the glow even more impressive.
To ensure uninterrupted service, a reliable and ultra accurate Swiss Made Ronda 715Li quartz movement powers the watch. The movement also features a legible date display between 4:00 and 5:00. A long-lasting 10-year lithium battery ensures more time on the wrist and less time getting serviced.
Constructed out of carbon fiber reinforced polycarbonate, this lightweight watch weighs in at only 3 ounces. The dial is well protected by a scratch resistant sapphire crystal with an anti-reflective coating.
When your adventure involves water, this watch is ready to accompany you diving down to 200 meters. While in the depths of the sea, the unidirectional ratcheting diver bezel with two tritium markers will help you keep track of elapsed bottom time.

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 two tritium elapsed minute markers.
Swiss-Made Ronda Movement
The watch is powered by a reliable and accurate Swiss-Made Ronda 715Li quartz movement with a 10-year lithium battery. 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.
