A 5218-201 A LUMINOR PANERAI SAN MARCO
A 5218-301A MARE NOSTRUM SAN MARCO
They were handed out to donators to save the Piazza San Marco in Venice. They wanted to raise funds for the building of the dam in the lagune in front of Venice. If you donated $500 you got a Panerai with a quartz in it, with 'san marco' on the dial. Panerai supported this, you know being a brand involved with the sea etc.
They are very common, a few thousands of them have been distributed.
........If they are so common, Why haven't I seen one yet? Anyone here knows or seen one? Imagine a 201a or Mare Nostrum in Quartz...
