The Luminox Navy Seal Colormark 25th Anniversary Edition 3051 Watch has a rugged and technical look. Night illumination is color-coordinated mirroring the colormark Navy Seal series. The 44mm case, case back and unidirectional ratcheting bezel are all made of molded carbon-reinforced polymer. The crystal glass, a hardened and tempered mineral glass, is highly scratch resistant. The double-gasket, push-in crown and construction of the watch case ensure water resistance to 200 meters.
