L’Astronomo — Luminor 1950 Tourbillon Moon Phases Equation of Time GMT — 50 mm

The Astronomo debuted in 2010 to mark the fourth centenary of Galileo's observations of celestial bodies. This second model incorporates an equation of time, sunrise and sunset times, a GMT function, a moonphase display on the back which is personalised for the wearer's chosen location, and a novel date display on a polarised borosilicate glass disc. The laser-engraved numerals remain virtually invisible until they align with the small date window, whose polarised crystal then brings them into view. This patented innovation perfectly integrates the watch's design by leaving a clear view of the mechanism. Note the Panerai tourbillon, visible front and back, which rotates at right angles to the balance rather than parallel to it.
