THE POWER RESERVE LETS THE WEARER CHECK REMAINING POWER AT ANY TIME BY AN INDICATOR ON THE DIAL. This function was developed by Officine Panerai's master watchmakers who created a transmission system connecting the barrel's winding spring and the movement's gear train with the power reserve indicator, which moves as the winding spring transmits the accumulated energy to the movement wheels. The case of the Luminor Power Reserve - 44 mm, made of polished steel, is water-resistant to 30 BAR (~300 metres) and has the characteristic drawbridge: the mechanism was designed by Officine Panerai to protect the crown but most of all to make it waterproof, as it is one of the most delicate parts of a watch when immersed in water. The dial of the Luminor Power Reserve - 44 mm, with a black or blue background, bears the unmistakable Officine Panerai style: large markers, luminescent Arabic numbers and hands, all of which guarantee exceptional visibility under all conditions of use. In addition to the small seconds dial at 9 o'clock and which is constantly moving, the watch also has an arched sector between 4 and 5 o'clock: this is the power reserve indicator, marking off the number of remaining hours of power. Above that is the date indicator, with a magnifying glass inserted in the 3.5-mm thick, non-reflective sapphire crystal. In the Panerai Luminor Power Reserve - 44 mm, this complex watch function is regulated by an exclusive automatic movement: the Panerai OP IX calibre, an automatic movement 13 ¼ lignes in diameter, with a C.O.S.C. chronometer certificate, with 21 rubies and 42 hours of autonomy when fully charged. It is characterised by the personalised Officine Panerai bridges and the oscillating weight.


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.
