George III Oak Longcase Clock, circa 1800

• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• George Iii - George III (1738 - 1820) was King of Great Britain and Ireland from 1760 to 1820.
• Dial Plate - The dial plate is the front plate of a clock or watch, and may have the numerals painted or engraved on it, as well as cut-outs for the hands, date apertures, strike/silent adjustment or automata. On some clocks a chapter ring, displaying the numerals may sit on top of the dial plate.
• Oak - Native to Europe and England, oak has been used for joinery, furniture and building since the beginning of the medieval civilisation. It is a pale yellow in colour when freshly cut and darkens with age to a mid brown colour.
  
  Oak as a furniture timber was superceded by walnut in the 17th century, and in the 18th century by mahogany,
  
  Semi-fossilised bog oak is black in colour, and is found in peat bogs where the trees have fallen and been preserved from decay by the bog. It is used for jewellery and small carved trinkets.
  
  Pollard oak is taken from an oak that has been regularly pollarded, that is the upper branches have been removed at the top of the trunk, result that new branches would appear, and over time the top would become ball-like. . When harvested and sawn, the timber displays a continuous surface of knotty circles. The timber was scarce and expensive and was used in more expensive pieces of furniture in the Regency and Victorian periods.
• 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.
• Satinwood - Satinwood is a dense pale gold coloured timber that was imported into Britain in the second half of the 18th century, and early 19th centuries from the East Indies and the West Indies. The name derives from the satin-like surface sheen when the timber is polished.
  
  It was used in the solid, as a veneer and in inlays. As well as furniture, satinwood was used for making musical instruments, barometers, boxes and clocks.
  
  It will usually be found on only the very best quality objects, presumably because of of its cost at the time.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
