Founded by Josef Girard and Urs Schild in 1856, Eterna is a Swiss luxury watch manufacturer based in Grenchen. Eterna developed the first KonTiki model in 1958 to commemorate a daring expedition across the Pacific. The watch series was an instant success and became a very important milestone for the company. In 1962, Eterna developed the Super KonTiki model for professional divers. It was named “Super” because it was the most water-resistant of the Kontiki series back then. Its enlarged, easily legible luminous indexes allow divers to time decompression stops correctly during ascents. The present example, preserved in overall great condition, is a rare and fine watch for connoisseurs of vintage diver's timepieces.
