Lens-shaped proprietary automatic movement

The calibre Eterna 3030 is inspired by a traditional proprietary movement from the early 1970s. It’s marked out by its domed design on both side of the movement.

The 3030 calibre draws inspiration from the past

In 2006, Eterna's watchmakers decided to rework on the calibre 1504 dated from 1974 to create the actual 3030. The slim, domed movement was taken as a base, only a few details were changed to benefit from the new technologies and a big date with two discs was added.
