Guido Panerai developed a brand new crown protection to make the Radiomir 1940 case even better waterproof. He invented this waterproof winding system before WW2. But it was a military secret at this time.
PAM 673 comes with a dark brown Ponte Veccio strap with beige stitching size 26/22 BA 1275 from factory.
The energy comes from a PANERAI in house movement P.3000. It has 160 parts and delivers the energy for 3 days. PAM00673 is limited to only 1000 watches.
This OFFICINE PANERAI represents the iconic diving watch that Guido Panerai made for the Italian navy. Very Rare!
