1240H

Automatic movement featuring an adjustable 24-hour display, alarm function, power reserve gauge, and an alarm on/off status indicator. A dual-hand 12-hour sub-dial at 3 o'clock indicates the alarm setting, while an 8 o'clock pusher utilizes a column wheel to toggle the alarm, visible via a 12 o'clock on/off aperture. A hammer and gong mechanism creates the chime, and the self-winding system powers both the timekeeping and alarm reserves. Additional: Power Reserve Indicator.
