"The Isobrite Valor Series by ArmourLite offers the world's first T100 tritium illuminated ultra lightweight polycarbonate watches. The Valor
Series watches feature a Swiss Ronda 715Li Quartz movement with a 10-year lithium battery, an anti-reflective scratch resistant sapphire
crystal, two tritium markers on the unidirectional bezel, and water resistance down to 200 Meters (20 ATM / 660 FT).
Unlike ordinary tritium watches that use T25 tritium illumination, the Isobrite watches use ultra bright T100. This makes them up to 4
times brighter than the rest! The T100 tritium markers are manufactured by Switzerland’s mb-microtec and are currently the brightest and
most advanced tritium illumination available on the planet.
In addition, while most polycarbonate watches use mineral crystals, ArmourLite made the Isobrite watches with an anti-reflective scratch
resistant sapphire crystal. Sapphire is the same crystal material used on high-end fine watches by Omega and Rolex."
