Luminor 1950 L'Astronomo Tourbillon Moon Phases Equation of Time GMT

In Context

At 50 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 144 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 28,800 vph the seconds hand advances 8 times a second.

PAM00920 stands on its own in this catalogue — no other reference here shares its base number. It pairs a skeleton dial with a titanium case. It was a limited edition. Introduced in 2018. Beyond the time it carries a gmt and a tourbillon.

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 personalized to operate in accordance with the geographical coordinates of a place chosen by the owner. It provides the same range of 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. This 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 polarized crystals. 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.
