In the late 1930s, Panerai made a very limited number of Radiomir watches with a special 12-sided bezel, engraved with the words “OFFICINE PANERAI–BREVETTATO”. This inscription referred to the patented luminous substance Panerai called Radium and indeed it was luminousity was from decaying radioactive material. The stamping on the bezel suggests that these watches were used more as prototype submissions presented to the authorities of the Royal Italian Navy who were evaluating new instruments for underwater missions.
This new Radiomir 3 Days Acciaio PAM 687 is a Special Edition made in only 1000 individually numbered pieces and completely sold out! 2 distinct features make this watch very unique, cool and immediately eye catching -
#1. 12-sided bezel in brushed steel. This bezel is shaped like a stop sign with smoothed, polished angles, deep beveled edges and original era type-set engraving on the bezel 'OFFICINE PANERAI BREVETTATO.' 'Brevettato' means 'Patented' and refers to the Panerai's proprietary substance called Radium and used on the hands and dial for luminescence. It is believed Panerai stamped this on the bezel to designate the watch as a prototype not to be used for military operations but rather presenting to the authorities of the Royal Italian Navy for evaluation purposes.
#2. Ghost Brown and White Dial - so called Ghost for its rarity and because of its faded look. This 'Ghost' dial was reproduced to mimic the tropical or fading effect of the original Panerai dials where Radium was generously applied to the hands and dial. It took a number of years to find out the Radium had an unpredictable side effect of shocking the black coated brass dials to fade into unpredictable brown and even bleached white hues. <That’s exactly what happened to one of its most famous watches, reference 6154. Nicknamed the “Egiziano Piccolo,” it was commissioned by the Egyptian Navy in 1954, specifically because they required the properties of Radiomir for underwater use. On December 14, 2012, Christie’s presented one of the last remaining examples, a badly discolored reference 6154 with a pre-sale estimate of $80,000 to $120,000. But far from turning collectors off, its tropical dial captured their hearts. A few hours later, the brown reference 6154 would become the most expensive vintage Panerai ever sold, smashing its estimate at $326,500.> Remarkably simple and minimalist, Panerai's patented 2-layer sandwich dial maximizes the legibility of the already oversized hour markers and allows the watch to glow like a flashlight at night!
