Pelikan Sovereign D600

In 1929, Pelikan was the first company in the world to introduce the differential piston mechanism. This technology uses two different thread pitches inside the fountain pen to ensure that the spindle inside rotates faster than the filling handle. To this day, this fountain pen exists in many variations and although it has been constantly developed in design and technology, the basis of the mechanism has remained the same.
In 1950, the model 400 was launched on the market and today, with its green striped coat, it stands worldwide as a symbol for the Pelikan brand. In the 1980s, the series was christened Sovereign, but popularly it is nicknamed Stresemann in memory of the striped suits worn by the foreign minister of the Weimar Republic. After the Black-Green and Black-Blue models already enjoyed great popularity, another tasteful color variation was added in 2001 with the Souverän Black-Red. The striped pattern on his coat.
