This Cartier Lady Tank Diamond Replica Watch is Swiss made of stainless steel and diamonds case with high quality Japanese Quartz watch movement. The dial is silver colored with diamonds on the dial (most likely not real diamonds.) But it looks quite like the real deal. It has a minderal crystal glass face which effectively resists scratches better than regular glass, but not quite as good as sapphire crystals. This watch is not waterproof, dont swim with it on.
