Hamilton Watch Jazzmaster Power Reserve H32635131. True to hallmark Jazzmaster classical elegance, the boundless energy of the artfully designed 80 hour power reserve movement is contained in a sleek stainless steel case. For the first time, the extended power reserve is visible on the wrist through the power reserve scale, located at 9 o clock. With archetypal Hamilton ability to combine watchmaking excellence with utterly modern appeal, this traditional and highly useful horological complication has been reinterpreted in a smooth red tipped arc elegantly fitting the Jazzmaster design. The new H13 movement, tailor made for Hamilton, is tastefully decorated and visible through the case back for a complete watchmakers feel.
