Lum-Tec

Ohio-based microbrand founded by Chris Wiegand in 2007, named for the brand's signature MDV (Maximum Darkness Visibility) multi-layer Super-LumiNova application — some of the brightest lume in the watch industry. Lum-Tec produces dive watches, field watches, and chronographs across the M, V, B, and Phantom collections, typically with Miyota or Seiko movements.
