67592: NUT,SELF-LOCKING,EXTENDED WASHER.
The BC22 Classic Analogue Alarm clock is unique in form. Its silhouette is derived from the AB 2 clock designed in 1984 by Dieter Rams. The clean simplistic dial and contrasting hands that feature luminous tips offers great legibility.
The addition of the iconic yellow second hand is synonymous with Braun’s award-winning design history and long-lasting aesthetics. As with all Braun products the emphasis is on prioritising usability and functionality and this is perfectly illustrated by the continuous backlight function that subtly illuminates the dial when in low-light environments. The unobtrusive backlight aids legibility, resulting in effortless time reading at night.
This function can also be disabled by the user. Among it’s features are a snooze and light function, as well as a crescendo beep alarm that once set is visible on the clock face with a green indicator. The BC22 is powered by a quartz movement that ensures the clock is quiet and precise.
