For Panerai, innovation is above all about functionality, and in the Panerai Submersible 1950 Amagnetic 3 Days Automatic Titanio it is seen in its special case construction which ensures a remarkable degree of resistance to magnetic fields: 40,000 A/m (ampere per metre), a limit more than eight times greater than the value specified by the international standards of the Normes de l’Industrie Horlogère Suisse (NIHS 90-10). Such a high limit is achieved by the use of a special internal case made of soft iron of the highest purity, which encloses and isolates the movement, forming a Faraday cage that diverts the flow of magnetic fields. The soft iron case is immediately beneath the dial, which is made of the same material.
