Manufactured in the 1940s, this Eterna is an exceptionally rare unused waterproof model equipped with the early bumper automatic movement Cal. 1159, featuring a silver two-tone Roman numeral dial.
Although it shows minor aging and small marks from long-term storage, it remains unused and comes complete with its original strap and original buckle, making it a highly valuable collector’s piece.
At a time when most Eterna watches featured simple luminous Arabic dials and manual-wind movements, this example stands out for its two-tone Roman dial, the use of the bumper automatic Cal. 1159, and the screw-back waterproof case — all hallmarks of the exceptional quality that defined Eterna in this era.
