In Depth

IN OFFICINE PANERAI'S PAST, THERE EXISTED A RARE, MYSTERIOUS VERSION OF THE RADIOMIR, of which only two examples dating back to the end of the 1930s are known, featuring a dial with a unique and original graphic style. The new Radiomir 3 Days Platino - 47mm by Officine Panerai draws on this unusual graphic, which has not been used since in the history of the Florentine brand. The new Radiomir brown dial, protected by a Plexiglas® crystal, features alternating bar markers - double at 12 o'clock, single at 3, 6 and 9 o'clock - and dot markers, in place of the typical large numerals at the cardinal points, which characterise Officine Panerai's classic dial. To ensure optimal readability, the dial has a sandwich structure, typical of historical models, comprising two superimposed plates, the upper one perforated at the hour markers to highlight the interposed luminescent material. The origin of this dial cannot easily be traced. According to some historians, the two surviving examples (differentiated by the presence or absence of the small seconds dial) were perhaps fitting samples that were not continued. The loss of the Panerai archive during the Florence flood of 1966 means no historical reconstruction can take place, but the watch, also due to the mystery surrounding it, has lost none of its allure in this latest edition. The Radiomir 47mm diameter case is made of platinum and is water-resistant to 10 BAR (~100 metres), a depth presumed to be the maximum possible for the original Radiomir. The case-back features a large sapphire crystal window to showcase the in-house movement, and the strap attachments, no longer welded to the case-middle as in the past, are removable wire loops (patented by Officine Panerai) that allow the strap to be changed easily. The case and watch reference details are engraved between the strap attachments. The Radiomir 3 Days Platino - 47 mm adopts the manual-wound P.3000 movement, designed and built entirely at the Officine Panerai Manufacture in Neuchâtel.



Platinum is a rare metal, one of the rarest and most valuable in the world: to obtain just a few grams, for example, it is necessary to mine and process up to ten tonnes of rock. Processing this raw material and turning it into an ingot of platinum takes five months of work, while in the case of gold only three tonnes of rock and five weeks of work are needed. When it was discovered in Colombia in 1750, the similarity of platinum’s appearance to silver gave it its name - plata in Spanish means “silver” - but in terms of value and simplicity of working, the two materials are very different.

Officine Panerai uses 950 platinum (Pt950 Ru, 95% pure platinum) and its specific weight is 11% heavier than 24K gold. This alloy is recommended for machining, but it is not suitable for casting and cannot be hardened by heat treatment. Ductile, malleable and corrosion-resistant, platinum requires a long, complex working process. Stamping a platinum case, for example, requires a specially calibrated press.

The tooling used is subject to greater wear, and meticulous cleaning of the technical instrumentation is required. The polishing stage is particularly complicated and very different from that used for gold, because of the particular characteristics of this material. It has to be carried out entirely by hand, since it cannot be done using automatic tools. The engraving stage is similarly very complex.



Platinum has a good level of hot and cold deformability. Air annealing can be carried out without difficulty. It is advisable to limit the number of times the metal is annealed and to carry out preliminary hardening of at least 30%. The time and temperature of annealing must be controlled to prevent enlargement of the grain (“orange peel” effect).


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.


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.
