Extremely rare gold French Art Deco square watch Circa 1925

White gold and enamelled as lapis lazuli watch by Cartier
–
A rare Swiss white gold and enamel Art Deco square watch, circa 1925. The watch has an 18K white gold case, uniquely enamelled as lapis lazuli and has a French punch. It is numbered 510, and the crown is set with a sapphire. The precision lever movement is super-thin and made by Inter Watch Co. Geneva. The typical Cartier dial is silvered, signed, and has Art Deco steel hands. Although the dial has some partial corrosion, it is in very good condition overall. The enamel is flawless, and the watch is in working order. It is an extremely rare find.
