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.
The porcelain-enamel dial on this Waltham timepiece is absolutely flawless, featuring bold black numerals with striking contrast and a classic railroad-style layout. Red minute markers trace the perimeter, while a sub-seconds dial sits neatly at 6 o’clock—an enduring hallmark of early-20th-century American design. Beneath the dial, the watch is powered by Waltham’s 15-jewel Seaside grade movement, crafted in Waltham, Massachusetts, and completed in 1906. Produced between 1896 and 1912, this movement showcases an exposed mainspring barrel and beautiful damaskeening (Geneva stripes). Every component was meticulously refinished: screws and hardware were heat-blued by hand using a precise open-flame technique (read more here), while the jewel settings, gear train, balance, and balance weights were individually hand-polished to restore their original golden luster. The hands remain in their original heat-blued finish, which connects this piece directly to its early American roots.
The timepiece is housed in our 40 mm surgical-grade 316L stainless steel conversion case—one of the most balanced and wearable sizes for any American conversion. The case features both crown and caseback gaskets, offering water resistance up to 50 meters, though it is best to remove the watch before swimming or submerging it in water. Fully serviced and tested, the piece is ready for years of reliable performance and everyday wear.
