AMERICAN CLASSIC RAILROAD AUTOHamilton never underestimates the power of a classic three hand watch that draws on our heritage, signature style and American spirit. From the railroads of old to the wrists of today, the automatic H 10 movement with 80 hours of power reserve and a dynamic dial design that calls to mind the wheels of early steam trains are made for each other.
