Waltham No. 220 Conversion from 1920

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.

This Waltham pocket watch was manufactured in Waltham, Massachusetts, and was finished in 1920. It is powered by the No. 220 grade movement, which is a 15 jewel Waltham in-house movement that was produced between 1896-1932. The movement has been restored and custom refinished with blue accents, and the movement screws have been finished in blue as well. The accents were created through thermally treating each movement part by hand to color the iron based components. The hands of the watch have been restored using the same thermal treatment process. The Waltham dial is porcelain-enamel with bold Roman Numerals and is in excellent condition. The watch is cased in a new silver-colored wrist watch conversion case so the watch can be enjoyed on your wrist. This case is designed with adjustable lugs making the watch easy to wind and set. The adjustable lugs also permit a more custom fit for different wrist sizes. The watch comes fully serviced and ready for your next adventure. Because of our dedication to preserving history, the original 14 karat gold filled pocket watch case will be included as well.
