Overview
A copper-finished die-cast metal watch fob depicting an early Caterpillar crawler tractor with an overhead loader mechanism. Manufactured by the renowned Leavens Manufacturing Company of Attleboro, Massachusetts, it features high-relief detailing and was designed to attach to a pocket watch chain.
Story
During the 1930s, heavy machinery manufacturers gifted custom watch fobs as promotional awards to skilled equipment operators. This fob captures the rugged industrial era when Caterpillar tractors reshaped American infrastructure.
Maker / Origin
Leavens Manufacturing Company operated in Attleboro, Massachusetts—a city historically known as the 'Jewelry Capital of the World.' Leavens specialized in struck metal badges, emblematic jewelry, and promotional advertising novelties for major American corporations throughout the 20th century.
Condition & Value
Shows honest age-appropriate wear, surface oxidation, and verdigris in the recessed areas. The original leather strap is missing. Light wear to the copper finish slightly reduces overall value, though the maker's mark remains legible. Vintage Caterpillar and heavy equipment watch fobs enjoy a steady collector market.
