Complete Movement

A complete movement is the full internal mechanism of a watch, including the parts needed to power, regulate, and display the time. Depending on the type, it may be mechanical, automatic, quartz, or chronograph-based. Complete movements are useful for repairs, restoration, donor parts, or movement swaps when the original mechanism is missing, damaged, incomplete, or beyond economical repair.
