The Nera watch design originated from an abandoned Tornek-Rayville homage project. The homage project was transformed into what soon would become the DNA of the Peren brand.

The Tornek Rayville TR-900 diver watch from the 60's is one of the rarest diver’s watch ever made. It was made by Blancpain for the US Navy’s Experimental Diving Unit for use by its Underwater Demolition Team divers, a unit that would later become known as the Navy SEAL’s. Only around 1,000 pieces were made, and most were subsequently destroyed because the watch was using a radioactive element. On the caseback there is a radioactivity warning sign followed by the instruction: "If Found, Return to Nearest Military Facility." Only 30 or less watches are still existing today.
