New Panerai model! PAM01628
Most of the models they have been adding are tiny 40mm women's watches, but this one is a big boy at the original 47mm size. Note the matte finish of the case
The closest Rolex model to this is probably the 6152.1 from 1963, when they first modified the Rolex case with the crown guard, along with LUMINOR on the dial. This one had the Cortebert 618 movement as opposed to the version that used the Angelus 240 8 day clock movement (the ones with the seconds hand at 9)
5 years later, the Italian navy would no longer order from Rolex and Panerai. Almost everything they did after that was an homage of these beautiful Rolex watches with Panerai dials.
