Both cases are made of polished 316L stainless steel and water-resistant to approximately 100 meters. The case of the Luminor 1950 (which is an evolution of the original, historical Radiomir case) features another Panerai hallmark, the distinctive bridge device with clamping lever to protect the winding crown. The casebacks have sapphire viewing windows that offer a view of Caliber P.2002/E, and specifically the power-reserve display, which has been moved here due to its traditional spot being occupied by the equation-of-time indication on the dial.
The Panerai Radiomir 1940 Equation of Time 8 Days Acciaio – 48 mm is a limited edition of only 200 pieces, and the Panerai Luminor 1950 Equation of Time 8 Days – 47 mm is even more limited, to just 100 pieces. Both timepieces are fitted with an alligator strap (black for the Radiomir, brown for the Luminor); the Luminor 1950 is also supplied with a screwdriver and a tool for changing straps.
