A display setting arrangement for a timepiece, having a 12-hour display, on which, driven in a rotatable manner by a basic mechanism with two revolutions every 24 hours, the hours can be displayed. There is also a second hour display, which can be driven in a rotatable manner likewise by the basic mechanism. By means of a correction device, the 12-hour display can be adjusted manually relative to the second hour display. The second hour display is a 24-hour display and can be driven in a rotatable manner, in a direct gear train, by the basic mechanism of the time piece with one revolution every twenty-four hours. Via a force-fit connection, a 12-hour gear train can be driven in a rotatable manner, for the purpose of driving the 12-hour display, by a direct-gear-train wheel which is driven with one revolution every twelve hours. In this case, a setting device which can be actuated manually, it is possible to adjust, separately from one another, either the direct gear train or, by overcoming the force fit of the force-fit connection, the 12-hour gear train relative to the direct gear train.
A display setting arrangement for a timepiece, in particular a wristwatch, having a 12-hour display, on which, driven in a rotatable manner by a basic mechanism with two revolutions every 24 hours, hours can be displayed, having a second hour display which can be driven in a rotatable manner likewise by the basic mechanism, and having a correction device, by which the 12-hour display can be adjusted manually relative to the second hour display, wherein the second hour display is a 24-hour display and can be driven in a rotatable manner, in a direct gear train, by the basic mechanism of the timepiece with one revolution every 24-hours, and wherein, via a force-fit connection, a 12-hour gear train is drivable in a rotatable manner, for purpose of driving the 12-hour display, by a direct-gear-train wheel which is driven with one revolution every 12-hours, wherein by means of a setting device which is manually actuatable, it is possible to adjust, separately from one another, either the direct gear train or, by overcoming the force fit of the force-fit connection, the 12-hour gear train relative to the direct gear train.
