In 2002 Patek Philippe released the Celestial (Ref. 5102) which is considered one of the most important horological complications ever developed. A remarkable rendition of the Northern Hemisphere's celestial chart is fitted dynamically upon the wrist for the first time. The celestial chart rotates counter clockwise, showing the progression of stars relative to the meridian passage of Sirius. Simultaneously, the meridian passage and phases of the moon can be seen. 25 trillion (25,000,000,000,000) ratio combinations were researched by Patek Philippe to determine the greatest accuracy for all the Ref. 5102's displays. These complications illustrate the tremendous challenges that the production of this highly sophisticated model posed to the company's watchmakers.
