A sketching set is as a combination of drawing devices for technical drawings, which are also known as “sketches”. Using these drawing devices, you can draw particularly thin lines, consequently achieving high precision.
In addition to various compasses, a sketching set also includes rulers, measures and prickers.
The sketching set depicted belonged to Hermann Goertz (1862–1944). Goertz used these instruments, amongst others, to design his astronomical clock, which can be found today in the entrance area of the German Watch Museum Glashütte.
Goertz was close friends with the teacher Alfred Helwig, who had been teaching at the German School of Watchmaking in Glashütte since 1913. He gifted him the drawing instruments once he himself could no longer use them due to health reasons.
