In Depth

THE CASE OF THE RADIOMIR BLACK SEAL CERAMICA - 45 MM BEARS THE SAME DESIGN AS OFFICINE PANERAI'S ORIGINAL, historic watch, made in 1938 for the Italian Navy, and is updated with a very innovative material. The Radiomir Black Seal Ceramica - 45 mm is evocative of the actions of the men of the Gamma group in the Italian Navy, who, during the Second World War used so-called SLC, slow torpedoes, also known as "pigs" or "black seals" for their manoeuvres. This Panerai watch model stood out for its case's structure, which guaranteed a high degree of impermeability thanks to its winding crown and the screwed-on case-back, while Radiomir, a luminescent paint containing zinc sulphur, mesothorium and radium bromide, gave the dial excellent visibility even in extreme conditions of use. With Officine Panerai's Radiomir Black Seal Ceramica - 45 mm, a new model is added to the collection: Officine Panerai's decision to use this high-tech material reflects the technical experimentation that Panerai has always aspired to, thanks to a solution that is interesting from both an aesthetic and technical viewpoint. The ceramic used is zirconium oxide and is worked as a powder using an isostatic pressure process that enhances the material's extreme hardness, great resistance to extreme temperatures and corrosion.


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.
