Although alarm movements had been widely produced in the 1950's, it was not until the following decade that automatic alarm movements were produced. A. Schild developed their own unique automatic alarm movement and introduced it in 1973 since quartz alarm watches had not yet been developed.
Unlike many other automatic alarm watches, the rotor winds both the alarm and timekeeping barrels. One direction of rotation winds the timekeeping barrel and the other winds the alarm.
This movement features two crowns, at 2 00 and 4 00
- The crown at 2 00 is used for timekeeping functions Manual winding, setting the day and date, and setting the time, in three positions, respectively
- The crown at 4 00 is used for the alarm Disabled in first position and enabled (and set) in second

- AS 5001 Manual winding
- AS 5004 No calendar
