Ornate 18ct Gold Pocket Watch with Guard Chain

• Guard Chain - In the 19th century and early 20th century, a guard chain was attached to a watch, and also an item of clothing, such as a buttonhole or a waistcoat to prevent the loss of the watch. For ladies, the guard chains were used to hold the ladies fob watch securely and sometimes were long enough to be wrapped around the neck a number of times and worn as a necklace.
• Fusee - The fusee movement was used in clocks and pocket watches from the mid 17th century. The fusee is a cone shaped drum within the works that is linked to the barrel of the spring, usually by a length of chain.
  
  As the mainspring loses its tension over time, the cone shaped barrel compensates for this by increasing the tension, by pulling the mainspring tighter, thus ensuring the time remains constant.
  
  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.
  
  The fusee continued to be used in marine chronometers until the 1970s.
