Design with practical use by Pieter Rams. The Braun Company from Germany produced it somewhere in the 1990’s. This small black quartz travelers clock comes with a working BCS (Battery Control System) and keeps time well…but the alarm does not go off. The model is AB6 and the type 4747. The design is classical Braun and it only measures 8 cm or 3 1/4 inches wide. There are small signs of use but nothing major selling as a cool time display piece only since the alarm does not work.
