This striking men"s watch from Reactor features high-quality craftsmanship with deluxe materials for both long-lasting durability and bold style. The striking blue dial offers a gorgeous contrast to the white, patented Superluminova-finished numerals and hands, which offer up to eight hours of low-light readability. The indexes, with their stylishly modern, oversized design, are easy to read, as is the handy day and date calendar located at the three o"clock position. A tachymeter forms the outer perimeter of the dial; the unidirectional bezel provides a very stylish touch as well as additional timekeeping functionality. The watch"s 40-millimeter case is constructed of sold, marine-grade 316L stainless steel for ultimate corrosion resistance, and the hardened mineral glass crystal offers extreme scratch and shatter resistance. The handsome stainless steel wrist band includes a fold-over clasp with a safety lock for additional security. Like all Reactor watches, each Critical Mass watch is individually tested to its depth rating of 200 meters. The watch is powered by analog quartz movement.
