THE LUMINOR GMT - 44 MM IS DISTINGUISHED BY A SECOND TIME ZONE, the date, excellent impermeability and a case with both a brushed and polished finish. The Luminor GMT's case is an updated version of one of the legendary models that Officine Panerai created for Navy commandos during the Second World War. At the time, there were no specialised underwater watches, and the Florentine manufacture was the first to create this watchmaking speciality with the Radiomir, and a short time later, with the Luminor models, which were easy to identify for their size and aesthetic qualities. The winding crown is made waterproof not by using screws, but by a bridge-like mechanism with a hinged section in the centre, which Officine Panerai patented more than half a century ago, and which still makes the watch immediately identifiable. The dial, in the traditional black, bears two large Arabic numerals and 24-hour linear markings, indicated by the slender central hand that makes a complete rotation not in 12 hours, but in 24 hours. Night-time visibility is guaranteed, as in all Officine Panerai models, by the exceptional luminosity of the numbers, indicators and the wide, partially skeletonised hands, while the anti-reflective sapphire crystal contains a small magnifying glass to make the date easier to read. The 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. The automatic movement is equipped with a Panerai OP VIII calibre, and is C.O.S.C. certified, making this watch even more exclusive and unique, not only from a technical viewpoint, but also aesthetically, with the small seconds dial at 9 o'clock as on the original. Another aesthetic element is the bracelet which has brushed-metal links, while the links inside are glossy, extensively polished by hand.



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 according 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. It is recommended that the strap 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. 


The Panerai bracelet can be washed with soap and warm water, using a soft brush. After this operation, and also after bathing in the sea or a swimming pool, rinse the bracelet carefully with clean water and dry it with a soft, dry cloth. It is recommended that links should be added to or removed from the bracelet by an Authorized Distributor or a Panerai Service Centre, in order to avoid any problems caused by incorrect replacement. 



Do not use the watch at a depth greater than that indicated.
