Wear a smartwatch with your Hamilton

Hamilton supplied field watches to the US Army and pilot watches to commercial aviation. The Khaki Field became the reference for tool watches at honest prices. The American spirit, as the brand calls it, translates as reliability without ceremony. Smartlet One fits Hamilton references the same way: practical, reversible, requiring no permanent change to the watch. The same lug holes take the original strap's spring bars or the Smartlet's watch adapters with equal indifference.
