ArmourLite Watch Company is an American company based in Miami, Florida established in 2007 by Ashley Diener, that designs and manufactures Swiss tritium illuminated watches under the brands ArmourLite and Isobrite.

With the success of ArmourLite, Ashley was inspired to continue to innovate and set new market standards. Thereafter, Ashley created the Isobrite brand as the first ever to offer Swiss T100 tritium illumination combined with ultra lightweight carbon fiber reinforced polycarbonate cases. Since then, Isobrite has become the market leader when it comes to affordable and ultra rugged T100 watches.
