Vince Toth
A surviving advertisement identifies a chess clock as 'Fabricação de V. Toth' and describes a solid wooden case, simple precise mechanism, metal switching rods, one-year guarantee, and São Paulo retail distribution. Later Brazilian chess sources remember Vince Toth not merely as a seller but as a maker.

What Remains Unknown About Toth
The advertisement has not been securely dated, no complete catalog has been found, and the exact model range remains unclear. The evidence nevertheless supports Toth as an early domestic manufacturer.
Jaehrig Begins with a Player's Need
Ralf Jaehrig, a professional watchmaker and chess player, states that he built his first clock in 1986 because he needed one for a tournament. That one-off need became a continuing business.
Illustrated record
From König to a Product Family
The first clock was called König. Subsequent Jaehrig-branded clocks began in wood and evolved through multiple cases and dials before moving into modern high-resistance plastic materials.
Analog and Digital Continuity
Jaehrig continues to produce both a wind-up analog model and a digital model with numerous preset programs and official Brazilian competition homologation.
Historical Sequence
Brazil therefore preserves both ends of domestic chess-clock history: an early locally made mechanical timer whose full production record is largely lost, and a modern manufacturer whose product evolution remains visible and ongoing.
