From the first production year, a PAM 9A PVD with Original PVD finish.  As shown with original leather strap and original PVD thumbnail buckle.

This has a tritium dial which could no longer be made after 2000.  An excellent example of the historic Panerai craftsmanship. 

There were only a few hundred of this model made and they have become a rare collector's item.  This Base model PVD set the standard for Panerai from 1997 on.
