Isobrite by ArmourLite is the world's first line of T100 tritium illuminated ultra lightweight polycarbonate watches.

The Isobrite watches (except ISO401) 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 200m of water resistance.

Unlike ordinary tritium watches that use T25 tritium illumination, the Isobrite watches use ultra bright T100 tritium. This makes them up to 4 times brighter than the competition! 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.
