Founded in Switzerland in 1856, Eterna was known for innovation. The Eterna-Matic was a self-winding watch introduced in 1948, which used 5 ball bearings to wind the mainspring. These ultimately became parts of the company's corporate logo. It is now a part of the Hong Kong based Citychamp Watch & Jewellery Group Limited.
