The Jazzmaster Auto Chrono is a watch that keeps up with modern life, beating to the rhythm of its movement. Dedicated to those who love tradition but with an eye to innovation, the H-21, with its 60 hours of power reserve, is housed in a case with soft curves and clean lines. The H-21 is a powerful automatic chronograph movement with an enhanced 60-hour power reserve, making it perfect for the needs of the sportiest models. The H motif on the oscillating weight leaves no doubt about who made this movement.
