A watch function or mechanism beyond basic timekeeping, such as a calendar, chronograph or tourbillon.
A complication adds a function, indication or mechanism beyond basic timekeeping. The term applies to mechanical and electronic watches, regardless of how the movement is wound. A calendar adds information about the date, while a chronograph measures an elapsed interval independently of the ordinary time display. These are different kinds of complication, with different mechanisms and checks. In production, watchmakers assemble movements that may include complications and then verify that the functions operate correctly. For a newcomer, the useful question is which additional function a watch offers and how the wearer uses it.

Harrods’ watchmaker role in Hammersmith included full services and partial repairs on pre-qualified Rolex calibres up to models with complication modules, once trained. The wording tied that scope to training rather than assuming every watchmaker covered every mechanism. It gives complication a direct workplace application within the limits of authorised servicing experience. Search local jobs for “complications”.
