For over a century, the Panerai family legacy has been intertwined with precision instruments made to accompany the Italian military in their exploits. Commissioned by the Royal Italian Navy to supply high-precision instruments, it was Guido Panerai’s Radiomir - a radium- based substance that illuminates for visibility in the dark – that began it all when it was patented in 1916.
An archival receipt shows that the Radiomir prototype was presented in 1935, and over the years, the sandwich construction has been progressively adjusted and is currently made of only two superimposed plates. Other improvements include the crown-protecting device, and a new luminous substance, the Luminor. A watch produced strictly for the military, the forces used it until the early 1970s, with its designs protected by military secrets.
