In Depth

IN ABOUT 1940, THE PANERAI WORKSHOPS IN FLORENCE PERFECTED A NEW CASE, designed to meet the increasing demands of the commandos of the Italian Navy. The case was a development of the one presented in 1936 which is known today as the Radiomir – a term which originally referred to the luminous material patented by Panerai to make the dial readable in the dark – but it presented some innovations designed to make its construction even more solid and hardwearing. In the new case the strap attachments were no longer formed from a strong piece of steel wire bent and welded to the caseband, as they had been previously. This design might expose the watch to the risk of the strap coming off in the course of the extreme operations which commandos were called upon to undertake when on board their underwater assault craft. In the 1940s version, on the other hand, the lugs were larger and much more solid, being milled from the same block of steel as the case, of which they were an integral part. As well as the strap attachments, the system of attaching the strap was also changed, becoming much simpler and more secure. While previously it had been necessary to sew the leather round the wire strap attachments, the new construction had little holes in the lugs themselves in which a small tubular bar could be fitted, having been inserted through the loop of the strap. This was a more modern solution, which also meant that the leather strap could be replaced easily. As well as the modification to the strap attachments, other changes altered the Radiomir case in a definitive way, presaging the subsequent development of the shape of the Luminor case which came out a few years later. The cushion-shaped outlines were now less accentuated. The winding crown was slightly larger and cylindrical rather than troncoidal. The overall thickness of the watch increased from about 15 mm to almost 17 mm. So was born the Radiomir 1940 case which Officine Panerai is presenting again today – with the same design but in a thinner version – in new models of the collection, watches endowed with the strength and fascination that only being a part of history can convey. The Radiomir 1940 Oro Rosso has a case 42 mm in diameter with the P.999 hand-wound movement, the smallest and thinnest in the wide range of calibres produced by the Officine Panerai manufacture in Neuchâtel. The P.999 movement, visible through the sapphire crystal window set in the back, has a power reserve of 60 hours and a balance which oscillates at 21,600 vibrations/hour (equivalent to 3 Hz). The Radiomir 1940 Oro Rosso is supplied with a brown alligator strap.


Red Gold

Red gold is an alloy composed of gold, copper and other metals, and due to its technical properties and elegant appearance, it is an ideal material for use in fine watchmaking. 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. 5Npt has another important property: it has a high mechanical resistance than standard pink and yellow gold. It is the perfect material for Panerai high-end watches.


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.


Have watch checked periodically for water-resistance by an Authorized Panerai Service Centre and renovate it every two years with regular servicing, or whenever the watch has to be opened. The restoration of water-resistance necessarily involves replacing the seals in order to ensure the maximum water resistance and protection. Where the watch is used in underwater sports activities, it is recommended that it should be checked every year before the underwater activities begin.  


Have the movement of watch checked periodically by an Authorized Panerai Service Centre in order to preserve its perfect operation. If the watch has a tendency to gain or lose time to a significant degree, the movement may need to be overhauled. The movements are designed to withstand temperature variations between -10°C and +60°C (14°F and 140°F). Outside this range of temperatures, operational variations exceeding those set out in the specifications of the movement may be noticed. In addition, there is a risk that the lubricants contained in the movement may deteriorate, resulting in damage to some of its parts. 



To keep the exterior in perfect condition, we recommend washing Panerai watch with soap and warm water, using a soft brush. After this operation, and also after immersion in the sea or a swimming pool, carefully rinse the watch with fresh water. All Panerai watches can be cleaned with a soft, dry cloth. 


 Panerai straps must be washed in warm water and left to dry. It is important not to dry them on a hot surface or expose them to direct sunlight, because the rapid evaporation of the water could damage their shape and quality. After each immersion in the sea or a swimming pool, carefully rinse the strap with fresh water. It is recommended that the strap and the buckle should be replaced by an Authorized Distributor or a Panerai Service Centre, in order to avoid any problems caused by incorrect replacement. Only an Authorized Distributor or Panerai Service Centre can guarantee the use of genuine Panerai straps, properly designed to fit the dimensions of the case and manufactured according to the quality standards of the brand. All alligator leather used by Officine Panerai comes from farms in Louisiana, USA. Officine Panerai’s suppliers have committed to the highest standard of responsibility and have given their assurance that such farms in Louisiana contribute to the stable growth of wild alligators, thus protecting this endangered species. Panerai does not use leather coming from endangered species taken from the wild.


P.999 calibre

The P.999 is a mechanical movement combining reliability, robustness and precision and featuring the special structure with wide separated bridges that characterizes all the other Officine Panerai Manufacture calibres. With a 12 ligne diameter, equal to 27.4 mm, and a thickness of 3.4 mm, the P.999 calibre is slightly smaller than the other Officine Panerai calibres making it ideal for models which are smaller, both in diameter and in thickness, than the historical watches. With 19 jewels, a single barrel providing a 60-hour power reserve and small seconds at 9 o’clock, the calibre is made up of 154 components and beats time at a frequency of 3 Hz: this means that its balance wheel makes 21,600 alternations/hour. Equipped with adjusting screws, the balance wheel is protected by an Incabloc® anti-shock device while the regulating system of the flat spiral is of swan’s neck type in the pink and red gold version of the movement.
