It is impossible to understand the sensations experienced by the first aviators of the twentieth century, but Hamilton can replicate its pioneering spirit, creating models with modern materials such as steel and sapphire crystal. Add an automatic movement and a perfectly proportioned 42 mm case and you will have a new interpretation of a vintage piece. With an enhanced power reserve of up to 80 hours, the H-40 stands out for its aesthetics and boldness. The 80-hour power reserve, almost double that of the market standard, allows you to remove the watch on Friday and still hear it ticking on Monday.
