In Depth

The Radiomir 1940 Tourbillon GMT Oro Rosso – 48mm is an exclusive Special Edition of just thirty units in red gold, intended for devotees of luxury sports watchmaking. The Tourbillon regulator is one of the most sophisticated complications of high quality watchmaking, invented almost two centuries ago to eliminate changes of rate in pocket watches caused by the effect of gravity. In a traditional Tourbillon the balance-escapement assembly rotates continuously on its own axis to compensate for these errors of rate. In the Panerai P.2005 calibre, on the other hand, the cage which contains the balance and escapement rotates on an axis which is perpendicular to that of the balance instead of parallel to it, and a rotation is completed in thirty seconds, that is, at twice the speed of the traditional one. Thanks to these two simple but revolutionary innovations, the Panerai Tourbillon compensates better for inaccuracies, thus ensuring that the watch runs more evenly. Its fascinating rotation can be admired through the sapphire window set in the back and it is also indicated on the dial by a small indicator rotating within the small seconds dial. As well as the Tourbillon regulator, the P.2005 calibre of the new Radiomir 1940 also has the GMT 24H function, which indicates the time in a second time zone by a special central hand, with am/pm indication on the subsidiary dial at three o’clock. The local time can be quickly adjusted by the system which enables the hour hand to be moved in jumps of one hour at a time, without interfering with the minute hand or the running of the watch. With three spring barrels connected in series, the power reserve of this hand-wound movement is a good six days, and the power reserve remaining is indicated on the back. The Radiomir 1940 case with a diameter of 48 mm is made entirely of 5Npt red gold, a special alloy with a high percentage of copper which gives the gold a warm, elegant tone, and a percentage of platinum which helps to prevent oxidation. The lugs are milled from the block of the case and the wide polished bezel frames a sapphire glass crystal which protects the brown dial with satiné soleil finish; its design is of exemplary simplicity in spite of the richness of the indications. The legibility and clarity of the dial are also enhanced by its sandwich structure: the Super-LumiNova® which makes it visible at night is applied between two discs and its luminescence emerges through holes in the upper one corresponding to the hour markers. The Radiomir 1940 Tourbillon GMT Oro Rosso – 48mm (PAM00558) is water-resistant to five bar (~50 metres) and it is supplied with a brown alligator strap, closed by an adjustable red gold buckle, personalised Panerai.

Materials

Red Gold

Red gold is an alloy composed of gold, copper and other metals, and due to its technical properties and elegant appearance, it is an ideal material for use in fine watchmaking. The red gold used by Officine Panerai is a special alloy, different from standard red gold, called 5Npt.

Panerai 5Npt has a percentage of copper giving the material an intense red hue that is particularly elegant and sophisticated. Platinum is another fundamental element of the Panerai red gold alloy, as it helps to prevent the metal from oxidising. 5Npt has another important property: it has a high mechanical resistance than standard pink and yellow gold. It is the perfect material for Panerai high-end watches.

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.2005 calibre

The distinctive feature of the P.2005 calibre, entirely created by the Panerai Manufacture, is its sophisticated tourbillon regulator, a device originally designed for pocket watches, interpreted in an innovative way by Officine Panerai to achieve more accurate timekeeping. The tourbillon causes the balance wheel and escapement assembly to rotate continuously, thus correcting all the errors caused by gravity and possible friction. In the innovative Panerai tourbillon, the cage which contains the balance wheel and escapement rotates on an axis which is perpendicular to that of the balance wheel, rather than parallel to it. Additionally, while in a traditional tourbillon one rotation of the cage takes one minute, in the case of the Panerai P.2005 calibre the cage makes one rotation in 30 seconds. The greater speed and the particular arrangement of the balance wheel and escapement assembly enable it to compensate better for the running errors caused by the many vertical and horizontal positions of a wristwatch in the course of 24 hours. The tourbillon cannot be seen from the dial side, but is visible from the back of the watch; next to it is the indicator of the 6-day power reserve, displayed by a hand which moves in a circular arc. On the dial, however, as discreet proof of the presence and correct operation of the tourbillon, a small coloured disc is placed in the auxiliary small-seconds dial. Linked to the tourbillon cage, this disc moves at the same speed as the cage and therefore completes two rotations per minute.
