This Must De Cartier Tank Vermeil watch features a 925 silver case with a gold electroplated finish. It is powered by a manual movement and offers hours and minutes functions. The case measures 20mm in diameter. The watch is in good working condition overall, although the dial shows signs of crazing. It comes with an aftermarket leather band for a stylish and comfortable fit. As always let me know if you would like anymore types of pictures of the watch!
