A true time hand (16) is mounted concentrically with a civil time hand (23) and is adjusted once per day by a cam shaped to the daily time difference (8) and a rocker (9) which controls the amount of movement of spring loaded combs (34,36) after release of friction plate (24) by control finger (32). The display is preferably integrated with a perpetual time of month movement. |
