Braun’s legendary travel alarm clocks were loved by many even after production stopped. Starting around April 20, 2011, the new licensed production of these clocks are available. This is the equivalent to the AB5, originally designed by Dietrich Lubs with Dieter Rams in 1992. A reliable clock, the AB5 had a round case, and form-appropriate cylindrical battery case on which the clock was balanced, and a clear crisp crescendo alarm. Runs on one AA battery. Silent German movement.
