Cartier Gold and Vermeil Wristwatches with Spare Dial

• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Vermeil - Gold vermeil is sterling silver (.925 silver) plated with gold. The process originated in France around 1750. The technique was called fire gilding. Jewellery makers applied mercury and gold to the silver and exposed the metal to extreme heat. The heat caused the mercury to vaporize and the layer of gold to adhere to the silver. The qualify as vermeil, the gold layer with which the silver is plated must be at least 10-carat gold
  
  The mercury vapours generated by the heat caused many artisans to become blind, and France made this process illegal in the 1800s. Modern gold vermeil is usually created using an electrolytic process, which is much safer than fire gilding yet produces a similar result.
  
  Vermeil is usually found in jewellery and watches, and occasionally in dinnerware.
  
  In the White House, the residence of the President of the United States, there is a Vermeil Room sometimes called the "Gold Room," which houses the collection of vermeil bequeathed to the White House in 1956 by Mrs. Margaret Thompson Biddle. The Vermeil Room serves as a display room and, for formal occasions, as a ladies sitting room.
