The OP I is a Panerai-branded movement based on the ETA/Unitas 6497-1. This basic hand-wound caliber powered early modern Panerai watches when production resumed in the 1990s. Features hours and minutes only, no small seconds. The robust pocket watch-derived movement provides a 56-hour power reserve. Eventually replaced by in-house P.6000 caliber.
