RADIOMIR 1940, GREATNESS BEYOND TIME.
"The Radiomir 1940 is an evolution and also a substantial development of the first Radiomir series. In response to the very strict requirements expressed by the Royal Italian Navy, the watch was strengthened to become even more resistant under extreme conditions. The first change was the increase of the thickness of the case so that the lugs could be formed directly from the same steel block of the case. The wire loop strap attachments were replaced by an extremely solid monobloc construction. "
AISI 316L STAINLESS STEEL
"AISI 316L 1.4435 stainless steel is Officine Panerai’s material par excellence since it is highly resistant to corrosion and is hypoallergenic, making it ideal for contact with the skin. The Panerai watches created for the Italian Navy were made of austenitic stainless steel, a reliable material that was also resistant to the extreme environmental conditions in which the commandos operated."
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. With a diameter of 13¾ lignes (31 mm), the new calibre has a large bridge which is flanked by the small oscillating weight winding in both directions and the balance cock. The latter has twin supports, more secure and stronger than the customary overhanging balance cock with a single support. The supports have two screws for adjusting the vertical play of the balance staff. The balance wheel oscillates at 28,800 alternations per hour (equivalent to a frequency of 4 Hz). It is a balance wheel with variable inertia, that is, with screws enabling the rate to be adjusted precisely without altering the relationship of the balance spring and the bridge. Fitted with 31 jewels, the movement has a power reserve of at least three days, as a result of having two spring barrels connected in series. It is also fitted with the device which stops the balance wheel when the winding crown is pulled out, for synchronising the watch exactly. 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.Discover calibre
Panerai watches are produced to very high standards of quality. It is worth remembering that the mechanical parts run 24 hours a day when used, so the watch must undergo regular maintenance to ensure long life and good operation.
