The Pulsomatic, a digital timepiece with futuristic design, was first produced in 2010 to mark the fortieth birthday of the world's first LED digital watch, made by Hamilton. The liquid crystal display on the Hamilton Pulsomatic is powered by an innovative Swiss automatic movement, the H1970. Fully charged, the watch has a power reserve lasting 120 days. It also offers a scratch-resistant sapphire crystal and water resistance to a depth of 50 meters to meet the needs of today's fast-paced, robust lifestyle.
