Eterna caliber 3030

In 2006 the Eterna watchmakers decided to rework the calibre 1505 dating from 1974 in order to create the current calibre 3030. The advanced, cambered movement served as the basis. Only a minimal number of details were changed with the help of state-of-the-art technologies and a large date display with two discs was added.
