In Depth

THE POWER RESERVE OF EIGHT DAYS IS PART OF THE HISTORY OF OFFICINE PANERAI. Between the end of the 1940s and the early 1950s Panerai used a 16-ligne Angelus calibre which would run for eight days without being wound: a very long power reserve to meet the requirements of the commandos of the Italian Navy, who during their operations had to be able to rely on an instrument of complete and enduring reliability. This tradition lives again today with the P.5000 calibre, the new hand-wound movement with an eight-day power reserve which makes its debut in the new Luminor Marina 8 Days. The new timepiece respect the classic aesthetics of the Luminor Marina, notable for the minimalist design of the case and dial. The case is 44mm in diameter and it is immediately recognizable by the bridge device with locking lever to protect the winding crown and it is available in AISI 316L stainless steel. Constructed of two superimposed discs ensuring the clearest legibility, the black dial has large baton hour markers and figures, with the small seconds dial at 9 o’clock. The P.5000 hand-wound mechanical calibre, visible through the sapphire crystal window set in the back, has been completely developed and made in the Officine Panerai manufacture at Neuchâtel. With a diameter of 15¾ lignes and a thickness of 4.5 mm, it is very robustly constructed. A large plate with brushed finish and diamond-polished chamfering almost completely conceals the mechanism, while revealing the variable inertia balance which oscillates at a frequency of 21,600 vibrations per hour. The long running time is achieved by two spring barrels connected in series which store the power reserve of eight days. The Luminor Marina 8 Days (PAM00510) is part of the Luminor Collection and it is completed by a strap of black leather.



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. AISI 316L, a specification of the American Iron and Steel Institute, is an austenitic stainless steel alloy with a chromium content of 16–18%, 11–14% nickel and 2–3% molybdenum.

Officine Panerai uses the low-carbon variant of this alloy: the lower carbon content of the steel improves its welding qualities where the metal’s thickness is 6mm or less. The excellent technical qualities of this material make it an essential element of every new Officine Panerai collection.


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.5000 calibre

A power reserve of eight days and hand-wound: the P.5000 calibre combines these two characteristics which are part of the history of Panerai watches since the first models created for the commandos of the Italian Navy. With a diameter of 15¾ lignes (35.7 mm) and a thickness of 4.5 mm, the P.5000 calibre has 21 jewels, it is made up of 127 component parts and its balance wheel oscillates at a frequency of 3 Hz, equivalent to 21,600 vibrations/hour. Its original, very strong structure recalls that of old movements in which the mechanism was contained between two plates concealing most of the wheels and allowing only a few details to be seen, such as the balance cock and the intermediate wheel. The P.5000 calibre has a variable inertia balance, its period of oscillation being adjusted by turning the little timing screws on the outside of the balance wheel. Using this system the balance spring is free, without the curb pins which would otherwise be used to modify its active length. The bridge supporting the balance is fixed by two screws beneath which are threaded rings which turn in both directions, the purpose of which is to adjust the endshake of the balance staff pivots. This technical solution helps the escapement to continue running perfectly in the event of shocks. The long power reserve of 192 hours, that is 8 days, is achieved by coupling the two spring barrels with toothed rims in series. The twin assembly enables longer, thinner springs to be used, resulting in a longer duration and greater uniformity in delivering energy to the movement.
