American Waltham Watch Co. was in operation from 1852-1957 and was an American pocket watch manufacturer. Manufacturing of Waltham watches took place at their facility in Waltham, Massachusetts.

Crafted in Waltham, Massachusetts, and completed in 1899, this Waltham timepiece features the grade No. 250 movement—a 17-jewel Waltham in-house movement produced from 1896 to 1928. The movement has been fully restored and refinished with stylish blue accents on the screws and movement hardware, achieved through precise thermal coloring completed by hand. The watch hands have also been restored using the same process. The Waltham dial is porcelain-enamel and in excellent condition featuring elegant Roman Numerals.

The timepiece is encased in a 316L stainless steel wristwatch conversion case, designed with adjustable lugs for easy winding and setting, ensuring a comfortable 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 engaging in water activities. The timepiece comes fully serviced and ready for your future adventures.
