See also an interesting article, about the differences among the two versions (of the Luminor and Mare Nostrum 1993-1997 models) Officine Panerai Florence and Panerai-Richemont Group, written by Maurits Bollen on Paneristi.
We remember that the Mare Nostrum, in these two editions, Officine Panerai Florence and Panerai-Richemont Group, is not accepted by us for the registration to the Club Panerai, because this watch was not never officially given to the Italian Navy, see Panerai Award 1995, during and after the 2nd w. w., not like the Radiomir and the Luminor models.
