In Depth

THE LUMINOR GMT - 44 MM WAS INSPIRED BY THE WORLD OF THE SEA. The Greenwich meridian was essential to sailors: they used Greenwich Mean Time in their calculations to determine longitude, and therefore to establish where their ship was located. The very modern GMT function on Officine Panerai's Luminor lets the wearer simultaneously read the local time and that of another country, displayed on the dial with a separate hand. Officine Panerai's Luminor GMT - 44 mm bears in it the tradition, reliability and exclusiveness that are typical of the brand: the technical heir to the historical Luminor models, the new Luminor GMT model is as fascinating as its illustrious forebear. Unlike Officine Panerai's historical model, the case is 44 mm thick for wearability during diving, and is slightly thinner than the original model which measured 47 mm. The large horns and especially, the characteristic drawbridge are the unmistakable elements of Officine Panerai's Luminor GMT. When the bridge is raised, the crown can be pulled out to adjust the three main hands or to wind the watch; the closed bridge guarantees a tight seal for the crown when it is pressed firmly against the middle. Waterproof to up to 300 metres, the case is completed with the bezel and the screwed-on back plate. The dial also boasts the classic Officine Panerai style, with large reference markers and luminescent Arabic numbers, but is also enriched with an external ring with 24 hours. The third central hand rotates around this 24-hour ring, and, when adjusted using the crown, indicates the second time zone. The semi-skeleton hour and minute hands are covered with luminescent material, as is the small second hand which rotates in its own grey dial. The date window is symmetrically located, and is easy to read thanks by the magnifying lens inserted in the sapphire crystal which is anti-reflective and very thick (3.5 mm) to resist pressure during diving. The automatic movement of the Luminor GMT - 44 mm is equipped with a Panerai OP VIII calibre, making this watch even more exclusive and unique, not only from a technical viewpoint, but also aesthetically, successfully keeping the small seconds dial at 9 o'clock as on the original. 42-hour power reserve and C.O.S.C. chronometer certificate.


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.
