In 1995, Panerai created a highly limited special edition called Slytech. "Sly" is the nickname of Sylvester Stallone, the famous Italian-American actor. Stallone, a great admirer of this watch, had requested a special edition called Submersible to use during the shooting of the underwater scenes in the movie Daylight and subsequently requested a new edition with a white dial, named Daylight, and a personalized re-edition of the Mare Nostrum. All these watches bear the actor's signature engraved on the back.
