The REF. 5102 "Celestial" astronomical wristwatch is equipped with a highly complex and sophisticated function which is extremely unusual for wristwatches. The planisphere of the Northern Hemisphere rotates counterclockwise on its dial and is enhanced by a construction of multiple stacked sapphire crystals, which move independently at different speeds creating a mesmerizing impression of depth. The celestial is meticulously mapped out on a sapphire crystal with Sirius (the brightest and first visible star) as the index, that rotates over a blue sapphire crystal dial that shows the angular progression of the stars relative to the meridian passage of Sirius. At the same time, a small round aperture with an adjustment index also indicates the meridian passage and the progressing phases of the moon within a lunar cycle (in a wheel with 279 teeth to reproduce the orbit of the moon). For this important invention, Patek Philippe was awarded a Swiss Patent (CH 688 171 B5).

In 2002, Patek Philippe created an important astronomical wristwatch with their celestial invention within a remarkably slim 18k white gold watchcase- REF. 5102. Its newly developed automatic movement with the Sky Moon mechanism (Caliber 240 LU CL) composed of 301 individual parts that are meticulously hand-finished in the workshops of Patek Philippe, positively reinforced Patek Philippe's unparalleled status in technological innovation of horology.

The REF. 5012 is an important addition to the Patek Philippe line of complicated wristwatches and its production is highly restricted in view of the movement's complexity and the effort involved in crafting, assembling and regulating this watch. It exists not only as one of the most desired masterpieces of horology for connoisseurs today, but also as a tribute to the watchmaker's effortless combination of form and function.
