Panerai Radiomir Black Seal Logo 45mm

In order to meet the military requirements of the Italian Royal Navy, to which Guido Panerai's family had been supplying precision instruments, such as naval combat sights, for years, a radium-based powder was developed to make the dials of instruments and sights brighter, in collaboration with Lieutenant Commander Carlo Ronconi: this is how the Radiomir was born.

The reference to the name "Radiomir" was documented in the addendum of the patent filed in France on March 23, 1916. The high self-luminescence of the compound immediately made radium paste a key element in Panerai's production. The Radiomir patent was the first of the many patents filed to celebrate Panerai's history of innovation.
