The PAM00380 is one of the watches announced by Panerai at the recent S.I.H.H. 2011 conference. This Radiomir Black Seal watch is part of their Historic Collection.

This new watch can be compared to the current PAM00183, but there are several major differences that sets this model apart. The most visible design change is the dial. The PAM00380 does not have the sandwich dial like the PAM00183 but instead features a painted dial. It also sports the Panerai logo on the dial.

The other difference is the choice of movement inside the watch. The PAM00380 is fitted with the Panerai OPII calibre, while the PAM00183 is contains the Panerai OPXI calibre. Both movements are very similar, but the following differences distinguish them: The OPII does not have the swan's neck regulator, and lacks the higher quality finish of the OPXI. Because of these differences, the PAM00380 has been fitted with a solid case back.
