r years now, Eterna has been concentrating on expanding its manufacturing and portfolio of movements. Today, Eterna is on the verge of completing a task involving high precision and ingenuity, its Calibre 39. This movement is not only an industrial calibre, but also represents a family of calibres thanks to whose modularity the brand can produce 88 different variations using the same base movement.
Eterna patented the Spherodrive technology featuring ceramic balls on three concentric rings to facilitate the rotation of the barrel. This technology, further refined, has been applied to the new family of the calibres 39, which will be the spearhead of the manufacture.

The quality of the movement is top-notch. The entire line has Chronometer quality and the Spherodrive system has been further refined. The balance wheel's high inertia (16g/mm2) gives it a great deal of precision and stability. Furthermore, 68 hours of power reserve is guaranteed. All the chronograph functions are controlled by a column wheel, which in turn features a flyback function. The movement is "Swiss Made", but could in fact be described as "Grenchen made" as 70% of the components are manufactured in or around Eterna's hometown of Grenchen. http://forums.timezone.com/index.php?t=tree&goto=6434662&rid=0#msg_6434662
