Lum-Tec is a watch brand based in the United States that specializes in luminous watch dials and hands. Every Lum-Tec watch features their exclusive MDV Technology™ (Maximum Darkness Visibility). This is a special 8-layer application of ultra bright glowing superluminova photoluminescent material. The process consists of a chemical base layer, six luminous layers and a final clear layer on the top. The result, are some of the brightest watch dials and hands in the industry. Lum-Tec MDV technology is not limited to Lum-Tec timepieces, though, they can even reapply their signature lume to older watches whose luminous paint has worn out over time.
