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Use of the fusee in clocks was superseded by the "going barrel" in the mid 19th century and for pocket watches at the beginning of the 19th century.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.
important. Important is a word used in the antique trade to indicate an object should be ranked above other similar objects, and is therefore more valuable.
The object could be considered important because it is by a famous designer or maker, has been shown at a major exhibition, is of exquisite workmanship, is rare or is a "one-off", was made for an important patron, and so on.
Even further up the pecking order are objects that are described in catalogue descriptions as highly important or extraordinarily important.
The buyers premium is an additional percentage charge on the hammer price of the item, imposed by the auction house to cover administrative costs. The buyers premium percentage varies between auction houses, with a range of 12.5% to 22%.
