Braun’s legendary travel alarm clocks were loved by many even after production stopped. This is the equivalent to the AB1A, originally designed by Dietrich Lubs with Dieter Rams in 1994. A pared down, very small but reliable clock, the AB1A had no snooze function, but a clear crisp crescendo alarm, and runs on one AA battery, many say, for a solid year. Silent German movement. 2.25” square, 1” deep, small pop-up on/off switch with green dot, High precision quartz controlled German mov’t. Easy to read dial. Crescendo alarm.
