Hamilton Jazzmaster Power Reserve Auto 42mm Watch Transparent Caseback and a sporty designWhen tradition meets innovation, the results are rarely so harmonious. The Jazzmaster Power Reserve uses simple design outside to balance the strength of the new H 13 movement inside. Only the power reserve scale hints at the stamina of the 80 hour reserve this model offers. For the Jazzmaster Power Reserve, Hamilton created the new H 13 movement with extended 80 hour power reserve, which is displayed on the dial through the power reserve indicator.
