The Panerai Radiomir was a 47mm diameter luminous dial and became the official watch of the Italian Royal Navy in 1938. Over the decades Panerai continued to design and manufacture submersible timepieces including the Mare Nostrum and Luminor. In the 1990s, Panerai chiefly catered to the public, thanks to the endorsement of action star Sly Stallone with his Luminor Chrono Daylight or Slytech. Current Panerai Collection are: Historic; Contemporary, Specialties and Special Editions.
