In 1962, Rado revolutionised watchmaking with its scratch-resistant DiaStar. Incorporating the bold and ageless appeal of the first DiaStar, the Original bears the features and functions Rado enthusiasts know and the distinctive look they love. The vertical faceted sapphire crystal shows the brown open heart designed dial with 6 cubic zirconia. The open heart designed dial gives a lighter to the automatic R764 movement with 80 hours of power reserve and sunray guilloche pattern decoration.
