"The fascination and the intensity of the blue of the sky and the sea applied to this new dial thanks to a new exclusive manufacturing process. Radiomir 1940 3 Days watches capture the innumerable evocative tones of blue by means of sophisticated satiné soleil workmanship, and thanks to the use of various shades of blue, the dial is tinged in such a way that the outer part is darker, more intense colour corresponding to the markers, which thus appear even more legible, and lighter towards the centre. "


The red gold used by Officine Panerai is a special alloy, different from standard red gold, called 5Npt. Panerai 5Npt has a percentage of copper giving the material an intense red hue that is particularly elegant and sophisticated. Platinum is another fundamental element of the Panerai red gold alloy, as it helps to prevent the metal from oxidising.

P.4000 calibre

P.4000 calibre

Officine Panerai presents the P.4000 calibre, the first automatic movement with an off-centre micro-rotor completely developed and made in the Panerai Manufacture at Neuchâtel. This design means that the rotor is mounted off-centre and is therefore smaller in diameter than the calibre itself: a sophisticated technical solution enabling the thickness of the movement to be substantially reduced. The small oscillating weight is inserted within the movement rather than superimposed upon it and the result is a calibre which preserves all the Panerai characteristics of accuracy, reliability and solidity but with a thickness of only 3.95 mm. The P.4000 calibre is produced in two versions which differ in the kind of finish, the engraving and the material of the micro-rotor. The first, for models with a steel case, has bridges with a horizontally brushed finish, blue engraving and an oscillating weight of tungsten alloy, with relief decoration on the matt surface. The second version is for the models with a gold case and it has bridges with a circular brushed finish, gilded engraving and a rotor of 22 carat gold, with clous de Paris hobnail finish and polished decorations in relief on the brushed surface.
