In Depth

IN THE 1930S AND 1940S, THE RADIOMIR AND LUMINOR NAMES IDENTIFIED THE LUMINESCENT SUBSTANCES USED BY OFFICINE PANERAI to increase the night-time and underwater visibility of watch dials intended for use by Italian Navy commandos. Over the years, the two terms have come to identify the shape of the cases of Officine Panerai's two iconic watches, one case representing the evolution of the other. The Luminor case was in fact born out of the need to make the Radiomir case even more resistant and watertight. This is why the crown-protecting device was added, shielding the crown and making it more watertight, with the strap attachments made from the same block of steel as the case replacing the welded wire lugs. The Luminor 1950 case represents another stage in the evolution of Officine Panerai cases. The case-middle of the Luminor 1950 3 Days – 47 mm by Officine Panerai, made of polished steel in the classic 47mm diameter, is rounded and cusp-shaped on the sides, a direct development of the cushion-shape case which still characterises Radiomir watches today. Other details are the result of a constant quest to both reclaim the past and strive for innovation: The flat case-back with large sapphire glass window which reveals the movement, the slightly thinner strap attachments which provide greater overall style, the Plexiglas® crystal, the engraving of the reference details between the lugs, the inscription “Luminor Panerai” no longer printed but engraved on the dial in period characters. The Luminor 1950 3 Days - 47mm by Officine Panerai has a P.3000 calibre, a manual-wound mechanical movement designed and developed entirely by Officine Panerai at its Neuchâtel Manufacture.

Materials

Steel

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.

Maintenance

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.

WATER-RESISTANCE 

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.  

THE MOVEMENT 

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.  

CLEANING THE EXTERIOR

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. 

THE STRAP

 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.

Movement

P.3000 calibre

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.
