The Radiomir Otto Giorni pays tribute to the first Radiomir prototype in 1935

Did you know that a Panerai watch was unavailable commercially until the 1990s? Founded by Guido Panerai, Panerai started by producing watches for the Italian military as they were coated with a radium-based substance called Radiomir that provided much-needed illumination in the dark. 

While the Radiomir substance was patented in 1916, the first Radiomir watch prototype was introduced in 1935. The watch was exclusive to the military until the early 1970s, with its designs being classified information. The first commercial Panerai watches debuted in 1996 but the first Radiomir, PAM 21 in platinum, was only made available for public sale in 1997 when Richemont (then the Vendome Group) acquired Panerai.

The new Radiomir Otto Giorni in 45mm referenced the 1935 prototype but in eSteel that contains up to 95 per cent recycled steel scraps from different industries.

To up its vintage appeal, Panerai has also given the material an antiquated look via the Physical Vapor Deposition process. Recalling the vintage Radiomir with its cushion-shaped case, slim lugs, sandwich dial, and cone-shaped crown, it is nevertheless an unabashedly contemporary timepiece with domed sapphire crystal and an open caseback. The indications are coated with Superluminova for visibility in dim conditions.

There are two different dials, a grainy brown dial (PAM01347) and a blue dial (PAM01348), with the colours gradually going darker as they move away from the centre of the dial. 

Available exclusively in Panerai boutiques, the Radiomir Otto Giorni is powered by the manual-winding P.5000 calibre with 8-day power reserve, as indicated on the dial by the “8 giorni brevettato” term at ‘3’.
