In 2002, Patek Philippe launched the 'Celestial', Ref. 5102, an astronomical wristwatch and one of the most important horological complications ever developed.  The watch depicts the planisphere of the northern hemisphere with an integrated moon-phases display, successfully reproducing the configuration of the visible sky with the apparent movement of the Milky Way, the position of the moon, and its progressing phases within a lunar cycle.

Its newly developed automatic movement with the Sky Moon mechanism (Calibre 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 in horology.  For this important invention, Patek Philippe was awarded a Swiss Patent for the base calibre (CH 688 171 B5).

The Ref. 5102J, sculpted in 18k yellow gold, was introduced at Basel in 2007 and was discontinued in 2009.  It was replaced by the Ref. 5102PR, made in platinum and 18k pink gold. 

百達翡麗於2002年推出5102型號「Celestial」，此款具備天體運行的複雜工藝腕錶是迄今鐘錶製造業最重要的錶款之一。腕錶設計將北半球的星體及完整月相顯示濃縮於精緻錶盤之上，借由銀河動態，月相及月行軌跡功能顯示，成功具象化一幅蒼穹圖，頓時浩瀚宇宙似乎觸手可及。

5102型號腕錶配備最新技術的「Sky Moon」自動上鏈機芯（Calibre 240 LU CL），由301個精密部件組成，並嚴格遵循傳統工藝全部於百達翡麗工廠手工組裝，充分體現此殿堂級品牌無與倫比之製錶工藝及創新精神。此項重要技術，也為百達翡麗贏得一項瑞士機芯專利（CH 688 171 B5）。

18K黃金材質的5102J型號腕錶於2007年首次在巴塞爾鐘錶展上面世，後於2009年停產。5102PR型號，鉑金及18K粉紅金雙重貴金屬款式繼而承接上市。
