Lum-Tec’s new Vortex D1 watch is solar-powered so you don’t have to fuss with battery changes. And when fully charged, it has six months of power reserve. In fact just a minute charge with bright sunlight will be enough for a full day. Five hours or more of bright sunlight can charge the watch to its full six months power reserve. The Vortex D4 features a 42mm diameter stainless steel case with a military-grade titanium carbide Carbide PVD hard coating, a 120 click luminous internal diver bezel (set with a separate crown), 200 meters of water resistance, and the Lum Tec’s two-tone glow X1 grade SuperLuminova with MDV technology. The watch also has a curved double-dome sapphire crystal with military grade polarized (double-side) anti-reflective coating. A military style strap is adorned with gunmetal PVD keepers and buckle.
