Lum-Tec introduces its first new timepiece for 2021, the solar-powered Vortex D4. The Vortex D4 features a 42mm 316L stainless steel case with a military-grade titanium carbide Carbide PVD hard coating, a crown-controlled 120 click luminous internal diver bezel, 200M/656ft water resistance, and the brand's signature 2-tone glow X1 grade Super-Luminova with MDV technology. Inside the watch lies the solar-powered Seiko VS42A quartz movement, which requires just a minute of sun for a full day of battery life and it can stay powered for six months when charged for five hours. 

Pre-orders for the Vortex D4 are available now with shipments set for July 2021.
