Family: ETA UnitasBased on ETA SA 6497.1
Manual-winding large-format caliber from ETA, used by Kudoke in early pieces prior to the introduction of their in-house Kaliber 1. Stefan Kudoke hand-engraved and skeletonized the expansive bridges, a feature that appealed to engravers. Production has been discontinued.
