Worker in factory manufacturing watch in Waltham Massachusetts - stock illustration

1850 Aaron Dennsion, David Davis, and Edward Howard set out to start the first fully American watch company - with watches built to have interchangeable parts. Indeed, what would later come to be known as the Waltham Watch Company broke ground on a style of watchmaking that would carry on through the 20th century until today. Dennis, Davis, and Howard set up their first manufacturing facility in 1851. In that year, production on their first watches began. By 1852, their first batch of watches was complete. It was in 1853 that Waltham settled on its first public name: Boston Watch Co. By 1907, American Watch Co. finally changed its name to Waltham Watch Co.
