The PAM00380 was initially introduced at the 2012 SIHH along with a few other black seal logo counterparts, which are a collection of watches that are a call back to the rich history of Panerai. The PAM00380 has a stainless-steel, round case that is 45mm in diameter and 15.2mm thick, with a solid case back, a scratch-resistant sapphire and a fluted crown. The dial is black with luminescent California dial hour markers and hands, with a small-seconds sub-dial at 9:00 pm and showcases the black seal and OP seal. The Panerai PAM380 is powered by the OP II caliber which is manually wound with chronometer certification and a power reserve of 56 hours. The case is paired with a black leather strap with a stainless-steel pin buckle. It has a water resistance of 100 meters (330 feet).
