Robert Morton 18ct Gold Pocket Watch, Edinburgh 1820

• Chapter Ring - A separate metal plate on the face of a clock, on which the numerals for the hours and sometimes parts of the hours, are displayed, usually wheel shaped and sitting on top of the dial plate. The chapter ring is often a feature of the clock and can be silvered or enamelled to stand as a contrast to its background. The hours are usually shown in Roman numerals, although in the late 19th and earlt 20th century, Arabic numerals became fashionable.
• 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  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.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.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Basket Weave / Basketweave - Basket weave is a decorative pattern that is often used in textiles, ceramics, furniture and other decorative arts. It is created by actual or simulated interweaving of horizontal and vertical threads or strips to create a pattern that resembles a woven basket.
  
  In textiles, basket weave can be created using various materials such as fabric, yarn, or ribbon. It is often used to create decorative details on clothing, upholstery, and other household items. Simulated basket weave can also be created using ceramic clay, timber or other materials, and it is often used to decorate pottery, tiles, furniture, silver and other decorative objects.
  
  Basket weave patterns can vary in complexity, from simple, straightforward designs to more intricate, elaborate patterns. The size and spacing of the interwoven threads or strips can also be varied to create different effects. Basket weave is often used to create a natural, rustic look and is often associated with traditional crafts and folk art.
