      "Thanks to the invention of the telescope, Galileo Galilei 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 the moon phases indication, a classic complication of high-end watchmaking which Panerai has interpreted in its own way and with an accuracy of a century. "


      "L'Astronomo is made to order and can be personalised upon request. The personalisation includes the choice of the case material, the colour of the hands, the engraving, the strap and other possible special features."

      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.
