Officine Panerai presents the left-handed version of the Luminor 1950 3 days – 47 MM, in which the winding crown and the device protecting it are at 9 o’ clock, on the left side of the case. Left-handed watches are very much part of the history of Panerai. The commandos of the Italian Navy had to wear several instruments on their wrists at once: not only the watch, indispensable for synchronising their attacks and for keeping track of the length of time spent in the depths of the sea, but also the compass and depth gauge. For convenience, some of them preferred to wear the watch on the right wrist, and for them Panerai created the watch with the winding crown on the left side, as can be seen in some rare contemporary examples which still survive today. The steel case of the Luminor 1950 Left-Handed 3 Days has a unique detail which distinguishes it from the classic Luminor 1950 case: the caseband has a cusped shape, hinting at the form of a cushion case. This little detail, picked up directly from some examples of the period, tells the story which brought about the transformation from the Radiomir, created in 1936, with a classic cushion case, to the Luminor, more massive in its proportions and identified by the device protecting the winding crown.
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 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.
CLEANING THE EXTERIOR
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.
The P.3000 calibre, created entirely at the Panerai Manufacture, presents the main characteristics of the Panerai movements in terms of structure and robustness, accuracy and power reserve. The diameter of the calibre is 16½ lignes, a substantial size which traces its origins from that of the movements which were fitted to the historic Panerai models. The calibre is immediately recognisable by its construction, which is similar to that of a three-quarter plate movement: a large bridge, next to another smaller one, covers the majority of the mechanical parts, and is fixed to the bottom plate by a series of screws of substantial thickness, thus forming a particularly rigid structure. The movement has 21 jewels and it uses two spring barrels connected in series. Such an arrangement enables long, thin springs to be used, which ensure the delivery of a more even force over a longer period of time, with a power reserve of 3 days. The balance wheel is notably large (13.2 mm) and it is the variable inertia type, with four adjusting screws arranged externally round the ring, so that the rate can be regulated without the need to remove the whole assembly. Held by a bridge with twin supports – a fixing much safer and more stable compared to the cantilevered single bridge – the balance wheel oscillates at a frequency of 3 Hz, equivalent to 21,600 alternations per hour. It is fitted with an Incabloc® anti-shock device and is free-sprung, so there is no regulating lever. With brush-finished bridges and chamfered edges – that is, with the edges smoothed and polished – the P.3000 calibre is also fitted with a device for the rapid adjustment of the time: a star wheel with 12 points and a small spring clutch enable the hour hand to be moved one hour at a time, without interfering with the movement of the minute hand or the operation of the watch.
