The Luminox Bear Grylls Mountain Series 3730, with a black Carbonox dial and black silicone strap, is based on the collaboration with the famous survivor and brand ambassador Edward Michael "Bear" Grylls. The watch is inspired by one of his early expeditions, the summit of Everest in 1998. Bear Grylls' signature is engraved on the case back, and his famous motto "Never give up" is inscribed around the beige edge of the dial.
