In Depth

OFFICINE PANERAI PRESENTED PANERAI COMPOSITE, a synthetic ceramic that is the result of an electrochemical ceramization process of aluminium at the 2010 Salon International de la Haute Horlogerie in Geneva. Very resistant and light, this material combines highly technical characteristics with the sporty elegance of Panerai watches. The Radiomir Composite Black Seal 3 Days Automatic – 45 mm has a Radiomir case made of Panerai Composite and a dial with date display at 3 o’clock. Another feature of this watch is the name ‘Black Seal’ printed onto the dial, a fascinating reminder of the history of the Florentine brand. Black Seal was, in fact, one of the names used to describe the slow-speed torpedoes used by the commandos of the Italian Navy in their underwater missions. Visible through the burnished sapphire crystal, the movement of the Radiomir Composite Black Seal 3 Days Automatic is the P.9000, with a power reserve of 72 hours achieved by means of two spring barrels powered by an oscillating weight that winds in both directions. With a diameter of 13¾ lignes and a balance that oscillates at a frequency of 4 Hz, the P.9000 calibre is also fitted with a stop-seconds device enabling the time to be synchronized with a reference time signal.


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 your watch checked periodically for water-resistance by an Authorized Panerai Service Centre and restore it every two years with regular servicing, or whenever the watch has to be opened. Restoring the watch’s water-resistance necessarily involves replacing the seals so as to ensure the maximum water-resistance and security. Where the watch is used in underwater sports activities, it is recommended that it should be checked every year before the season of underwater activities begins.  


Have the movement of your watch checked periodically by an Authorized Panerai Service Centre so as to maintain its perfect operation. If the watch tends to gain or lose time significantly, 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 your Panerai watch with soap and warm water, using a soft brush. After this operation, and also after bathing in the sea or a swimming pool, carefully rinse the watch with clean 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 to expose them to direct sunlight, because the rapid evaporation of the water could damage their shape and quality. After each bathe in the sea or a swimming pool, carefully rinse the strap with clean water. The leather strap is made from leather which has not been chemically treated, which gives it a very natural, soft feel. As a result of its characteristics, the colour and form of the leather tend to change with the passage of time while maintaining all of its beauty. 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 skins coming from fragile or endangered species taken from the wild.  


P.9000 calibre

The P.9000 calibre, created entirely by Officine Panerai and used in a series of Luminor 1950 and Radiomir models, is fitted with various functions: it is an automatic calibre with a 3-day power reserve and a unique technical design which makes these movements immediately recognizable. The calibre has a diameter of 13¾ lignes and numerous features: two barrels which guarantee 72 hours of power reserve; a single piece rotor which winds by moving in both directions thanks to an automatic ratchet device; a balance wheel with adjusting screws, oscillating at a frequency of 4 Hz. To house this movement, a specially made version of the Luminor 1950 case has been designed, keeping the proportions of the original but featuring a slightly less convex sapphire crystal which only barely protrudes from the bezel.
