Eterna Diane Quartz

European Watch Clock and Jewellery Fair 1979 BF 329
Horological high fashion : these two Eterna jewellery models feature rectangular or hexagonal silhouettes attenuated by softly curving lines. Deep blue dials framed by a slim gold border running along the diamondset bezel; silken mesh bracelet. Their very slim 18K, yellow gold cases contain a quartz movement. (ETERNA Diane Çuartz)
