Summary:A device that tests the chronometric precision of a watch movement or a watch includes a control device controlling a predefined cycle of motions passing through standard chronometric test positions, and a fine control device including a sequencer arranged to control the changes of chronometric test position of this movement, or respectively of this watch, in a multi-position sequence, after each measurement per position, and to start another multi-position sequence as soon as the preceding sequence finishes and which observes the predefined total duration of one cycle of several successive multi-position sequences. This sequencer is also arranged to manage the rate stabilisation durations, durations of measurement per position, and multi-position sequence durations.
