The original Ventura, presented in 1957, went down in watchmaking history as the world's first battery-powered electric watch. Creating an automatic version of a watch famous for its battery-powered movement is a bold move, typical of Hamilton. It's also the perfect tribute for a revolutionary artist and avid Ventura fan: Elvis Presley. The H-10 movement, visible through the skeletonised dial of this model, has an 80-hour power reserve, a tribute to the 80th anniversary of Elvis's birth.
