With the quartz crisis looming brands, including Cartier, had to get creative. From the brands inception through the mid 20th century, Cartier predominantly encased there watches in precious metals. As a means of lowering cost and therefor lowering the price point of entry into the prestigious brand, Cartier launched the Tank "Vermeil." It involved a process by which gold was plated on top of a  sterling silver base. Less precious metal coupled  either a handwound movement (ETA based) or Quartz further reduced production costs allowing for a more accessible price point for the masses.
