Very interesting Bueche Girod coin watch. It is the first time that I have actually seen 2 gold coins of various sizes being used to make one watch. The back utilizes the eagle side of the $20 U.S. gold coin and the dial shows a $5 U.S. gold coin. The 129 diamonds are pave` set in an 18K white gold plate. The lugs are also set with diamonds in white gold plates soldered on top of the lugs. The watch case weighs 38 gr. w/ movement and crystal and measures 35 mm across.
