The Junghans J98/2 has a reverse running 24 h indication and a pointer date that can be shifted with a pusher. The Junghans J98/2 was never delivered in series.

Description

The permanent 24-hour display transports the date once every 24 hours. The date display is loosely mounted and is fixed by a pawl. To set the date, press the lever in the case between 4 and 5 and operate the lever, which locks the wheel on which the date hand is fixed, one more time.

If this happens while the pin of the wheel is in contact with the 24-hour wheel, it can avoid this, since a spring-loaded bearing has also been designed here.

Simply ingenious!
