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