The essential lines of the case and dial are faithful to the unmistakable Panerai identity, being unaffected by the flyback function, which instantly zeroes the chronograph hands and restarts them without it being necessary to stop and zero them first. The blue chronograph seconds hand and the rhodium plated minute hand are centrally mounted, so that the dial carries only the continuous small seconds counter at nine o’clock. The push-pieces of the chronograph functions are positioned at 8 o’clock and 10 o’clock, thus leaving intact the outline of the lever device protecting the crown which helps make the case of the Luminor 1950 water-resistant to 10 bar (about 100 metres).

The material of the Luminor 1950 case, 44 mm in diameter, is a synthetic ceramic based on zirconium oxide, which is up to five times harder than steel but substantially lighter in weight, as well as exceptionally resistant to scratches, corrosive agents and high temperatures. Every component of the case is individually moulded and undergoes successive stages of working and firing. The final bead blasting gives it an even, matt finish.

On the back of the case a large porthole in sapphire crystal reveals the P.9100 manufacture movement, the first chronograph calibre with automatic winding completely developed and made in the Officine Panerai manufacture, featuring a column wheel, two spring barrels connected in series which provide a power reserve of three days, a bidirectional rotor which winds the springs of the two barrels, and a variable inertia balance wheel which oscillates at 28,800 vibrations/hour (4 Hz).
