The first series of the Noblesse ballpoint initially had a rocker mechanism: pressing the top pushed the refill out, pressing the clip drew it back in. Because this clip mechanism proved too prone to failure, it was replaced during the production run by the usual push mechanism, in which the refill is moved solely by the button on the top.
The Noblesse line is frequently confused with the SL line, in sales listings as well; they are two separate ranges. Among the Noblesse versions were an all-steel model with a gold-plated clip as well as silver-plated and platinum-plated variants with a striped guilloche. The all-steel version with the gold-plated clip last cost 49 Deutsche Mark in the shops in 1992.
