Rare 1713 Gold Pair-Cased Pocket Watch by Daniel Delander

• 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  Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.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.
• Pair Cased - A pair cased watch is one with a double case. The movement is encased, and for additional protection this is fitted into an outer case.
• Verge Escapement - A verge escapement is an early mechanical escapement used in clocks and other timekeeping devices. It is an early form of the escapement mechanism, which is used to regulate the movement of the hands of a clock or watch. The verge escapement consists of a vertical shaft called the verge, which is mounted on the clock's main plate. Attached to the verge are two pallets, which engage with the teeth of the escape wheel. As the escape wheel turns, the pallets alternately lock and release it, allowing the movement of the clock to be regulated. The verge escapement was widely used in early mechanical clocks, but it was eventually replaced by the more accurate and reliable anchor escapement.
• Cartouche - An ornamental panel in the form of of a shield, oval or rectangular scroll with curling edges. It may be carved into the back of a chair or the top of a sideboard, or present on a piece of silver or jewellery, and contain the initials of the original owner, heraldic symbols, or some other inscription, such as the details of a presentation.
  
  In ceramics the term defines the central area of a vase or similar with a decorative border in one of the shapes above, into which a decorative scene or figures have been painted.
• Date Aperture - A date aperture is a cut out section in the face of a watch or clock, displaying the day of the month.
• Back Plate - On many types of clocks, the movement operates between two plates, usually made of brass, one at the back, and the other at the front, which forms a mount for the dial.
  
  On English bracket, mantle and table clocks the backplate was often visible through a glass door or panel from the late 17th century, and could be profusely engraved with scrolling decorations, flowers, foliage, birds, and figures. The engraving could also include the maker?s name.
  
  The amount of engraving reduced and became simpler as the 18th century progressed, and by 1800, had been reduced to a border, often with the maker's name in the centre. By the early 1800s all decoration had ceased, and only the maker's name was added, and by the Victorian era, most bracket, mantle and table clocks had no engraving.
• Laurel Leaf - The use of the laurel leaf as a decorative element can be traced back to ancient Greece and Rome, where it was closely associated with victory and honour. In these cultures, the laurel was a sacred tree that was dedicated to the god Apollo and was believed to have protective and healing properties.
  
  In ancient Greece, the laurel wreath was awarded to victors in athletic competitions, such as the Olympic Games, as a symbol of their achievement. The wreath was also associated with academic achievement, and was often worn by scholars and poets. The Greeks also used the laurel leaf as a symbol of victory in war, and it was often depicted in artwork alongside images of triumphant warriors and heroes.
  
  The Romans continued this tradition, and the laurel wreath became a symbol of the highest military honor, the triumph, awarded to victorious generals. The wreath was also used to crown emperors and other important officials, and was often depicted in Roman art and architecture as a symbol of power and authority.
  
  The laurel leaf is still used as a symbol of achievement, success, and excellence, and is frequently used in logos, emblems, and other branding materials. Its association with victory and honour has made it a popular choice for awards, medals, and other forms of recognition.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• 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.
