For me they are the beginning of the toolwatch. So beautiful, pure and full of history. Partly with a Rolex movement, the vintage Panerai's are a big part of my passion and Rolex heritage. Used for the German and Italian Combat divers in the 40th and later series also used by divers in the middle-east. The straps olden so great and the dials often turn brown. Which looks so cool. Only downer,... they became much to expansive for me and their high radiation. It ain't a daily beater .... but almost nothing can beat them cooooolwise. Here are some watches from friends..
