Braun's widely acclaimed reputation for innovative product design goes back to German engineer and inventor Max Braun. From the mid-1950s, the Braun brand was closely linked with the concept of German modern industrial design and its combination of functionality and technology. Dieter Rams, a key figure in the German design renaissance of the late 1950s and 1960s, served as the head of Braun's design staff and many of his designs have found a permanent home at the Museum of Modern Art. A true incarnation of German perfectionism, Braun is not merely a trademark. It stands for an all-encompassing concept. Radio-controlled clocks display the correct time, down to the exact second. How? They are synchronized to the atomic clock in Colorado and receive signals from a radio system operated by NIST (the National Institute of Standards and Technology). This means that you should never have to adjust your radio-controlled clock. During the transition from standard time to daylight saving time (DST) they "spring forward" one hour, and in the fall, when DST has ended, they "fall back" one hour.
