Family: OP
The OP IV is an automatic caliber produced by Panerai. Based on the widely used ETA 2892-A2, it has been modified to display the date in addition to the time. As a modified base movement rather than an in-house development, it represents a period when Panerai relied on third-party foundations before transitioning to its own manufacture calibers. The OP IV has been discontinued.
