Silva is a Swedish brand that has been producing navigational equipment for sailors worldwide since 1933.
The brand's history began with the invention of the liquid compass. This design was invented by two Swedes, the Kjellström brothers, who filled a compass with liquid, which held a magnetic needle in a zero-gravity environment. The accuracy of this compass, its minimal error, and its small size made it popular.
In 1939, the Kjellström brothers improved the liquid compass model by creating a needle damping system for greater navigational accuracy.
