摘要： A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.

摘要： A micromechanical mechanism (1), in particular for an horological movement (3), the mechanism including a micromechanical device including a mobile element (8) needing to be moved mechanically to trigger its operation. Included is a system for actuating the device, the actuation system including a mobile striker (16, 17, 18) configured to go from a release position (19) to a percussion position (21) in which it transmits to the mobile element (8) a momentum necessary for the release of the device, the actuation system further including a magnet (15) configured to attract the mobile striker (16, 17, 18) in a percussion position (21). Also a horological movement (3) including such a mechanism (1).

摘要： 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.
