This Swiss manufacture actually has American roots. It was first incorporated in 1892 in Lancaster, Pennsylvania, and produced its first watches in 1893. Hamilton went from building pocket watches to wristwatches and was famously in many a big-screen movie throughout the 1950s and ‘60s. Today, owned by the Swatch Group, it continues to be actively involved in the world of film (and even sponsors the Behind the Camera awards), aviation, and more. Its best-known lines include the iconic Ventura, the Jazzmaster, and the Khaki.
