These gargantuan yet classic dimensions are replicated in the 47-mm diameter, polished, rose-gold case of the Radiomir 1940 Oro Rosso (Italian for “red gold”), whose shorter, Paneristi-friendly reference number is PAM 00398. The gold used for the case is 5NPt, an alloy with an unusually high percentage of copper (24.1 percent) for a richer, redder hue. A smattering of platinum in the alloy (.4 percent) aids in protecting the case against oxidation. The screw-down crown on the right side of the case bears the vintage “OP” logo for “Officine Panerai.”
The brown dial contrasts nicely with the rose-gold case and echoes the color of the brown alligator strap. Like other Radiomir dials, it uses Panerai’s signature “sandwich” construction, in which two thin plates surround a layer of Super-LumiNova. The Arabic numerals and hour indices are perforated apertures on the upper plate, allowing the luminosity to shine through. The hour and minutes hands, as well as the small seconds hand on the subdial at 9 o’clock, are also coated with Super-LumiNova. The engraved logo on the dial is executed in 1940 period lettering and the case and reference numbers are engraved between the lugs. The curved crystal above the dial also contributes to the historical authenticity: it’s made out of 3-mm-thick Plexiglas, like the one in its historical predecessor, rather than sapphire.
The movement in the watch also contributes to its vintage appeal: Panerai’s OP XXVII, which is based on a caliber made by the legendary Swiss movement specialist Minerva, now owned by Montblanc, Panerai’s sister brand in the Richemont Group. The manual-wind 16 3/4-ligne caliber is visible through a sapphire caseback window. Among its attributes are a variable inertia balance with swan’s neck micrometric regulator, a Kif Parechoc anti-shock device, and a Glucydur balance that beats at 18,000 vph. It has a power reserve of 55 hours.
The Radiomir 1940 Oro Rosso is offered in a limited edition of 100 pieces, at a retail price of $55,500 each. There is also a Radiomir 1940 Special Edition in a steel case (PAM 00399), with a polished finish and a black dial, also limited to 100 pieces, that retails for $29,800. For the first 50 numbered models of each, Panerai has created 50 boxed sets containing both watches; the boxes are priced at $85,300.
