Hamilton Watch Co. was in operation from 1892-1969 and manufactured some of the highest end, most accurate watches ever produced. Manufacturing of Hamilton watches took place at their facility in Lancaster, Pennsylvania.
This Hamilton timepiece was crafted in Lancaster, Pennsylvania and completed in 1930. It is powered by the Hamilton 904 grade movement, a 21 jewel in house caliber produced between 1928 and 1936 with only 4,100 units made. The 904 features a jeweled motor barrel and a bridge plate layout that places the entire gear train on display, a view that is genuinely impressive in person. All components were carefully refinished. Screws and hardware received traditional hand thermal coloring, producing vivid blue accents that add both corrosion resistance and visual character (read more here). Jewel settings, the gear train, balance, and balance weights were individually hand polished to restore their warm golden luster. The dial side is equally striking. It features a beautiful Hamilton dial with applied golden indices and a guilloche motif that radiates from the center of the subdial. The hands retain their original heat blued color, which contrasts beautifully against the dial. A rare movement paired with a beautiful dial—an exceptional piece in every respect.
The timepiece is encased in a 316L stainless steel conversion case, designed with adjustable lugs for ease in winding and setting, ensuring a tailored fit across various wrist sizes. The case includes front, back, and crown gaskets, providing water resistance up to 50 meters, though it is recommended to remove the watch before participating in water activities. The watch comes fully serviced and ready for your next adventure.
