ArmourLite Watch Company is an American company based in Miami, Florida by Ashley Diener, that designs and manufactures Swiss tritium illuminated watches under the brands ArmourLite and Isobrite.
Through an exhaustive research and development process, ArmourLite created a shatterproof crystal, which became known as Armourglass. With a lab-tested hardness of 6,000 Vickers, Armourglass far surpasses the strength and durability of traditional watch crystals. For comparison, most crystals have a hardness of only 700 Vickers. With this breakthrough, ArmourLite became the industry's first brand to combine shatterproof glass construction with tritium illumination.
