History Founded in Lancaster, Pennsylvania, in 1892, the Hamilton Watch Company became legendary for producing "The Watch of Railroad Accuracy." By the 1950s, Hamilton was innovating with electric watches like the Ventura but continued to produce high-quality automatic mechanical watches like this "K-Series" line. These models were part of Hamilton's strategic shift to compete with Swiss imports, blending American case designs with robust Swiss automatic movements to offer the best of both worlds.
