The D4 brings together all the right qualities of an affordable dive watch in a way no one else has done. First of all, its movement is powered by the sun. A mere six hours of sunlight will keep it running for six months in the dark. Secondly, its 38mm diameter is better at accommodating most wrists, and combined with the 12.7mm thickness the D4 Solar can easily fit under a shirt cuff. It also has the right dive chops including a tough sapphire crystal, unidirectional bezel with aluminum inset, screwdown crown and caseback, C1 Super-LumiNova lume, and a 200-meter depth rating. Finally, the D4 Solar is assembled in America, providing solid craftsmanship in a sea of foreign-built timepieces.
