Abstract: A dynamic chronometric testing of a movement or of a watch, control device fine controlling a predefined or random cycle of movements via standardised chronometric testing positions, the rate parameters are also measured in dynamic positions where the acceleration and velocity are different to zero and which correspond to additional dynamic chronometry criteria, defined to qualify the rate during a continuous movement applied to the movement or respectively to this watch.

Abstract: A stand assembly is configured to store at least one smart watch band. The stand assembly has a stand base plate, smoothly connected to a stand top plate with a stand neck. A top rack is operably connected to the stand top plate. A stand top plate rounded slot width is less than a top rack rounded slot width creating a stand top plate rounded slot ledge. The stand top plate rounded slot ledge is configured to accommodate a pin of a smartwatch band.

Abstract: 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.
