Manufacturing of Hamilton watches took place at their facility in Lancaster, Pennsylvania.* This Hamilton timepiece, crafted in Lancaster, Pennsylvania, in 1935, features a distinctive secometer complication and is powered by the 912 grade—a 17-jewel in-house movement produced from 1923 to 1937. The secometer complication was pioneered by American watchmakers in the early 20th century and was only present on higher end movements. Components were carefully refinished with blue accents on the screws and hardware using precise, hand-applied thermal treatment—a traditional watchmaking technique that enhances both corrosion resistance and visual appeal (read more [here](https://www.frettclockworks.com/blog/the-art-and-science-of-thermal-coloring-for-pocket-watch-conversions)). The watch hands were not restored and are in their original heat blued condition applied by Hamilton at the time of manufacture. The jewel settings, gear train, balance, and balance weights were each individually hand-polished to restore their original golden sheen. The Hamilton dial is in excellent condition, showcasing Arabic numerals and the rare secometer complication. Instead of the standard sub-second dial at 6:00, the watch features a rotating disc to display the passage of seconds. The blue hands provide striking contrast against the dial, offering a visual delight each time the time is checked. **Price**: $2,249, But negotiable—especially to someone with an interest getting into vintage American watchmaking. **Case**: 316L stainless (surgical grade steel), 44 mm diameter, 47 mm lug to lug (52 mm with crown), 13 mm height, front/back sapphire crystals that are AR coated. Front, back, and crown gaskets provide 50 meters of water resistance although it is recommended to take the piece off before water activities.
