摘要： An isochronal correction system for mechanical clock movements, such as automobile clocks, enabling clockworks which have been isochronally balanced within acceptable limits to perform satisfactorily in a predetermined gravitational position, such as vertically to meet the most general or usual service mounting of the clock, nevertheless providing for utilization where for some reason, such as variation of position or accessibility of the usual clock-setting stem, the clockworks must be mounted in a different position in which it has been rotated beyond the plus or minus degrees of variation permitted by the standard, i.e., vertical, orientation accommodating the original isochronal correction. To this end, means in the form of a weight relationship on the balance wheel are provided to compensate for the deviation from the standard balancing relationship. Thereby performance characteristics substantially equivalent to the standardized isochronal correction are maintained without requiring special construction, rebalancing, or adjustment of the various parts of the clockwork assembly.
