Eterna S.A., Grenchen
Swiss watch company
The basis of the Eterna Watch Company was founded in 1851. Schild Frères, as the company was then known, started to produce ladies’ wristwatches from adapted small pocket watches.
It was specially noted for its automatic rotor bearings, which was symbolized by its five-points logotype in form of a pentagram and denoted by its Eterna-matic brand; by its alarm travel clocks; and by its Eterna-matic Kon Tiki model.
