Overview
This is an authentic World War I era Waltham 3/0-size movement housed in a gold-filled B&B Royal screw-back case, featuring bold luminous-style numerals and a sunken sub-seconds dial. The serial number 21055247 dates the mechanical movement precisely to around 1918, during the height of American involvement in the Great War.
Story
In 1918, pocket watches were entirely useless in the mud of European trenches. Watchmakers adapted small pocket movements like this 3/0 size into wristwatches, forever changing how humanity wore time.
Maker / Origin
Founded in 1854, the Waltham Watch Company pioneered the American System of Watch Manufacturing, using interchangeable machine-made parts to revolutionize timekeeping. During World War I, Waltham produced thousands of precise timepieces for military personnel, setting international standards for reliability under extreme conditions.
Condition & Value
Fair to poor cosmetic and mechanical state. The winding crown and stem are missing, the dial shows patina and degradation around the numerals, and the hands are oxidised. Restoration or replacement parts will be needed to make it functional.
