Eterna became famous for inventing the ball-bearing system for mounting the automatic winding rotor on movements, hence the company logo of five ball bearings. Eterna was also the founder of ETA, a staple movement used in many Swiss manufactured watches. Eterna reserved the best of these movements for their own watches. The Sevenday represents a series of day/date watches with advanced design. The present example has an anatomically-designed cushion-shaped case and an extremely nice factory original bracelet.
