Welcome to the Help area of the Encyclopedia.
The Help area is intended to provide short explanations for concepts and vocabulary rather than complete authoritative articles on particular horological subjects.
Help articles should generally be about a paragraph long.
Do not post longer articles here but rather put them in one of the main Encyclopedia Subject areas.
Do not ask questions here about particular watches, clocks or other horological artifacts. Those questions should be posed in the regular discussion forums. The Encyclopedia content is restricted to information that is generally accepted with little or no controversy. Whether a help note or a full article, it should be intended to satisfy the curiosity of the newcomer to the subject.
