This is a rare yellow gold and blue enamel Patek Philippe Reference 3885 Skeletonised wristwatch. The watch is powered by a manual wind Caliber 177 movement. The two part case in 18kt yellow gold has a transparent snap on case back. We belive this watch to be unpolished as all the hallmarks are perfectly visible and strong. The finely hand engraved skeletonised dial with blue outer enamel band with dot markers is just gorgeous. One can see the workings of the watch through the beautiful dial. This watch comes on an original Patek Philippe black croco strap with original solid gold Patek buckle. The original papers also come with this special watch.
