Eterna

European W atch Clock and Jewellery Fair 1979 BF 36
Seen from the front, these two models do not reveal their main - and impressive - feature : the fact that they are the world ’ s thinnest analogue quartz watches. And their styling truly matches their sophisticated technology : cases in solid 18K yellow gold, with fine square-pattern chasing for the model iith leather strap and “Clou de Paris” decor for the all-gold design. Note the lattert s perfectly integrated styling : its profile is an absolutely unbroken line - a master stroke - with the case and bracelet of equal thickness. These models are the first yielded by a new constructional approach whereby the case back also serves as the movement’s mainpiate and frame. Developed jointly with Ebauches S.A.
Neuchâtel, and ETA 5.A. in Grenchen. (ETERNA)
