Family: OP
The OP III is an automatic chronograph caliber based on the ETA 7750, modified by Panerai for use in their sports watch models. It represents the brand's pre-in-house era, serving as Panerai's primary chronograph movement before transitioning to proprietary calibers. The movement was discontinued as Panerai expanded its in-house manufacturing capabilities. It powered several notable Radiomir and Luminor chronograph references during its production period.
