A Watchmaker and Player
Ralf Jaehrig built his first chess clock in 1986 because he needed one for a tournament. The first design was named König.
Early Variation
Historical company displays show multiple forms between 1986 and 1994, documenting experimentation in cases and dials before a more standardized product family emerged.
Brazilian Production
The company states that its clocks and chess sets are produced in Brazil, and surviving packaging reinforces the domestic manufacturing identity.
Analog and Digital
The current analog clock uses wind-up mechanisms and requires no batteries. The digital model offers 42 preset programs and official competition homologation.
Historical Significance
Jaehrig shows a rare continuous national lineage from workshop-scale mechanical production into the modern programmable era.
