The Commercial Chain
A finished chess clock can pass through movement maker, assembler, wholesaler, importer, chess-equipment dealer, retailer, federation, and club. Any one of those organizations may leave the most visible surviving name.
Casa Zanzi
Casa Zanzi in Buenos Aires developed from an early games and billiards business and later sold chess equipment. In 1972 it advertised German chess clocks as exclusive distributor for the capital and Greater Buenos Aires. A Zanzi-branded clock can therefore preserve dealer identity and local market history even when the underlying mechanism came from elsewhere.

ELKA and Gardé
A German-made Gardé clock with an ELKA badge represents the same process in the Netherlands. ELKA was an Amsterdam watch-and-clock retailer, not the manufacturer of the underlying Ruhla/Gardé mechanism.

Why Badges Matter
Dealer plates can reveal export channels, store inventory, local pricing networks, and the commercial afterlife of products whose factory origins are already known.
The Attribution Trap
Retail marks become misleading only when treated as factory marks. The correct response is not to ignore them, but to assign them to the right layer of the object's history.
Historical Significance
Secondary branding is evidence of distribution. It explains how chess clocks moved from industrial producers into real clubs and homes—and why the same mechanical model can carry different identities in different countries.
