Eterna

With a history dating back to 1856, Eterna has consistently pioneered watchmaking innovations, most notably the revolutionary Eterna-Matic rotor bearing system using tiny ball bearings, which transformed automatic movement reliability. The brand invented the side-mounted rotor, leading to the development of ultra-thin automatic movements. Their KonTiki collection, named after Thor Heyerdahl's famous expedition, represents their expertise in robust sports watches. Today, Eterna continues to innovate in movement manufacturing through their subsidiary, ETA, while maintaining their reputation for technical excellence and reliability.
