The Rotring 600 was first released in 1989 .
Rotring descibes the 600 as their "entry into the upscale writing instrument market", "designed with a hexagonal barrell to prevent it from rolling on the architects drawing table. It is machined out of one piece of brass on a lathe, providing it with ample weight to ensure that the architect need not apply extra pressure when creating".
The Rotring 600 was originally made in Germany before production moved to Japan.
The early Rotring 600 pencils used to have a coarser knurling grip with the same pattern as the lead indicator.. At that time Rotring also released a similar Koh-I-Noor branded pen which shared the coarser knurling. One explanation for the transition to the later, finer knurling might be a desire to appeal Japanese tastes . The current (2018) knurling on the grip is the same as the one found on the early 600 ballpoint .
Over the years the mechanical pencil version of the Rotring 600 has been available in the following lead diameters
