In Depth

THE ASTRONOMO - LUMINOR 1950 TOURBILLON MOON PHASES EQUATION OF TIME GMT IS THE FIRST OF OFFICINE PANERAI’S CREATIONS TO HAVE MOON PHASE INDICATION AND AN INNOVATIVE SYSTEM USING POLARISED CRYSTALS TO INDICATE THE DATE. A REMARKABLE NEW MADE-TO-ORDER TIMEPIECE WHICH CAN BE PERSONALISED, ENHANCING THE SERIES DEDICATED TO THE GENIUS OF GALILEO GALILEI. Innovation and high quality watchmaking are combined in the L’Astronomo - Luminor 1950 Tourbillon Moon Phases Equation of Time GMT, the creation dedicated to Galileo Galilei. A Luminor 1950 case, whose iconic design is part of the fascinating history of Officine Panerai, encloses a concentration of technical solutions which demonstrate the ability of the Florentine brand to interpret traditional complications in ways which are always distinctive, bringing innovation into the world of high quality sports watchmaking. Like its predecessor, the new L’Astronomo - Luminor 1950 Tourbillon Moon Phases Equation of Time GMT is made to order, and the skeletonised movement, the P.2005/GLS (standing for Galileo Luna Scheletrato), is personalised to operate in accordance with the geographical coordinates of a place chosen by the client. It provides the same range of remarkable functions as the first L’Astronomo, and in addition, GMT and two other innovations: indication of the phases of the moon and an original system for displaying the date using polarised crystals. Thanks to the invention of the telescope, Galileo made revolutionary discoveries concerning the appearance and the movement of the moon. He made remarkably beautiful drawings of what he saw with an accuracy and attention to detail which is still amazing even today. So in a timepiece dedicated to him, nothing would be more logical than moon phase indication, a classic complication of high quality watchmaking which Panerai has interpreted in its own way and with an accuracy of a century. As well as the moon phase indicator, the hand-wound P.2005/GLS calibre also has the characteristic Panerai tourbillon escapement (Patented by Panerai), which can be admired both from the front as well as from the back of the watch thanks the sophisticated work of skeletonising the movement and the absence of an actual dial. In a watch with this construction, a date disc designed in the traditional way would to some extent conceal the fascination of the skeletonised movement, because it would cover part of the components. The Laboratorio di Idee at the Manufacture in Neuchâtel has therefore designed an innovative system – pending patent by Panerai – in which the date disc is made of borosilicate glass and the numbers of the days have laser-modified optical properties. The numbers are virtually invisible in all positions except for the one that is aligned with the little date window, where a further polarized crystal, situated above the date disc, causes the number to appear so that it is perfectly legible. As well as the technical personalisation of the P.2005/GLS movement, the new L’Astronomo - Luminor 1950 Tourbillon Moon Phases Equation of Time GMT also provides the opportunity of selecting the material and finish of the case, the colour of the hands and that of the Super-LumiNova® which makes the watch’s indications extremely readable even in the dark, as well as the colour and the material of the strap. In this way each client can create an individual watch of great character and elegance, for example choosing between a red gold or a white gold case, or the brushed titanium case of the main version of the L’Astronomo for a more sporty and functional appearance. In each instance, the watch is water-resistant to 10 bar (a depth of about 100 metres).

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/GLS calibre

The P.2005/GLS (standing for Galileo Luna Scheletrato) is the skeletonised movement of the L’Astronomo - Luminor 1950 Tourbillon Moon Phases Equation of Time GMT. It's personalised to operate in accordance with the geographical coordinates of a place chosen by the client. It provides the same range of remarkable functions as the first L’Astronomo presented in 2010 on the occasion of the 400th anniversary of the celestial observations made by Galileo as a result of the invention of the telescope, was the first timepiece created by Panerai with a tourbillon regulator, calendar, equation of time indication and the display of the times of sunrise and sunset and two other innovations: indication of the phases of the moon and an original system for displaying the date using polarised crystals. THE MOON PHASE INDICATOR On the back of L’Astronomo’s P.2005/GLS movement is a day/night indicator which clearly displays the phases of the moon, by means of a system consisting of two superimposed discs which rotate in combination. The upper disc – which is read by a small external index fixed onto the movement – displays the 24 hours of the day, showing the sun during the hours of daylight and the stars of the sky at night. At the centre of the starry sky is a little round window through which the lower disc can be seen; on this appears the moon, its shape evolving day by day as a result of a small supplementary rotation of this disc of about 6.1° per day, a figure based on the exact duration of one lunar cycle (an average of 29 days, 12 hours, 44 minutes and 3 seconds). Given that each watch movement is made according to the coordinates of a place chosen by the watch’s owner, the indication of the moon phases always relates to the sky above that place, and of course it also takes account of the difference between the earth’s northern and southern hemispheres. Like the moon phase indicator, the indicators of sunrise and sunset times are connected to home time and therefore, if the owner of the watch should find himself in a city with a different time zone from that of the chosen city, these indicators will continue to show the situation at the time at home, which is indicated by the GMT hand. Finally, at six o’clock is the linear indicator of the equation of time, which displays the difference between actual time (solar time) and conventional time on each day, this period ranging between plus 15 minutes and minus 15 minutes, according to the time of year. A POLARISED CRYSTAL DATE DISPLAY DESIGNED TO INTEGRATE PERFECTLY WITH THE SKELETONISATION OF THE P.2005/GLS MOVEMENT As well as the moon phase indicator, the hand-wound P.2005/GLS calibre also has the characteristic Panerai tourbillon escapement, which can be admired both from the front as well as from the back of the watch thanks the sophisticated work of skeletonising the movement and the absence of an actual dial. All the elements which would be found in a traditional dial appear on the movement or the flange, and the two spring barrels, which store enough power to last at least four days, are visible through the open back, which also enables the power reserve indicator mounted on the movement to be read. In a watch with this construction, a date disc designed in the traditional way would to some extent conceal the fascination of the skeletonised movement, because it would cover part of the components. THE TOURBILLON REGULATOR PATENTED BY PANERAI In the system patented by Panerai, the tourbillon’s rotation is different from that of the classic tourbillon. The cage of the balance rotates continuously on itself, to correct any alterations caused by gravity and possible friction. In this innovative mechanism patented by Panerai, the cage rotates on an axis at right angles to the balance, not parallel with it. Also, while the traditional tourbillon rotates once in one minute, that of the P.2005/GLS rotates once in 30 seconds, and its rotation can be seen by an indicator in the small seconds counter at 9 o’clock. The higher speed and the particular arrangement of the mechanism mean that any possible alterations of rate are effectively compensated, resulting in more accurate timekeeping.
