There are two new features introduced by Panerai with this model, starting with the material used to make it: titanium, which ensures greater lightness than steel and matches the warm brown tone of the dial on which the ecru SuperLuminova of the hour markers and hands stands out. The second feature that distinguishes this Radiomir from its predecessors is the adoption of the P.4000 calibre, the first automatic movement with an off-centre oscillating weight, entirely made by the Neuchâtel manufacture and visible through the sapphire crystal porthole on the caseback. Made of tungsten, the oscillating weight rotates in both directions thanks to two barrels connected in series, guaranteeing a power reserve of no less than three days.
