Braun's legendary travel alarm clocks were loved by many even after production stopped. Starting around April 20, 2011, the newly-licensed production of these clocks are available to limited retailers in the US. This clock is the equivalent to the AB30, originally designed by Dietrich Lubs with Dieter Rams in 1990. A reliable and classic design, the AB30 has voice or clap activated snooze function, and a clear crisp crescendo alarm, running on just one AA battery. Silent German movement.
