- Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
- Chronograph - A chronograph is a watch that also incorporates the features of a stopwatch, to measure elapsed time. Most chronographs are operated by two buttons, one to start and stop the chronograph second hand, and the other to return that hand to the starting position.
- Guilloche - A form of classical decoration consisting of a repeating ornament of interlacing curved bands, sometimes forming circles, and further decorated with rosettes or other flower forms.
The name is derived from the inventor, French engineer Guillot, who invented a mechanical method of inscribing fine repeating patterns on to metallic surfaces.
On enamelled items with guilloche decoration, the surface is firstly engraved with the repeating pattern, and then covered with several layers of enamel, each of which is fired.
Where the item has not been enamelled the form of decoration is usually called "engine turned".
