The Waltham brand traces its roots back to the 1850-founded Waltham Watch Company in Massachusetts, which pioneered industrial watch production and manufactured over 40 million timepieces. Today the name lives on under Swiss-based Waltham International SA, producing and marketing mechanical wristwatches in land, air and sea styles. While no longer the large American factory of its heyday, the brand carries forward its legacy of precision, heritage and utilitarian style for a modern audience.
