In
1995 the actor Sylvester Stallone discovered Panerai watches by chance and became a great fan of them.
He owned several pieces and asked Panerai to prepare, in a limited series a special watch to be used in underwater shots for the movie
" DAYLIGHT ", filmed in Italy at Cinecittà , and sugested that this model be named
Luminor Submersible.
Then he offered himself as testimonial for the production, in a limited and numbered series, of this watch and of new models, optimized for daylight, named
Luminor Daylight, besides as well as for a reissue of the
Mare Nostrum model.
On the back of all these watches is Stallone's signature, and on the dial the words
Slytech Panerai
2005 was the year of a new collaboration between Sylvester Stallone and Panerai with the launch of two new models Luminor Submersible Chrono 1000M – Slytech. Part of the wholesale price of each watch sold was paid as a royalty to the actor and then donated to a charity of his choice.
And if someone want to chime in with Slytech pictures

Here are the 2005, Pam 202 & 225 .....
