"The first ever micro-rotor automatic watch movement was patented by Uhrenfabrik Büren A.G. in the mid 50s. When their "planetary rotor" automatic movement was released in 1957 in the "Super Slender" line, it was one of the flattest automatics of its time and derivatives of the movement competed with the Universal Geneva micro-rotor for thinnest automatic in the world for many years. The most famous implementation of the Buren micro-rotor was to be found in Hamilton's "Thin-O-Matic" line. "
