Family: OPBased on ETA SA 6497.2
Manual winding caliber based on the ETA 6497-2. Features small seconds at 9 o'clock. A historic movement, it represents Panerai's early use of modified stock movements before developing in-house calibers. Now discontinued, it powered the first contemporary Panerai watches that established the brand's modern identity.
