The #Panerai 389 is a pretty interesting submersible. It's a 47mm case with a Ceramic disc inserted into the bezel which was a first for Panerai. A lot of people might also think that is is the first Amagnetic piece in their lineup but in reality the PAM92 that was worn by Mike Horn was the pioneer.
What is Amagnetic? Well beneath the dial a special soft iron case forming a Faraday cage that protects and isolates the movement from the flow of magnetic fields. This model guarantees a resistance to magnetic fields equal to 40,000 A/m (Ampère/metre), a limit more than eight times greater than the value specified by the international standards of the Normes de lndustrie Horlogère Suisse (NIHS 90-10). In extreme conditions, and in everyday life, watches are often exposed to magnetic fields generated by electric charges and currents. Such magnetic fields can noticeably alter the rate of the watch, a possibility that is virtually non-existent in the PAM389.
