Sorry, I'm a little late, but I'd like to show my waffle dial UG Polerouter Date!
It is a 218-2 microrotor.
The crown is not original and the crystal is a new "Sternkreuz 305/285" (in case you need a new one;-)
Unfortunately, serial and reference are no longer readable, but following
www.polerouter.de, it should be a 204612/1
The inner case back clearly shows 6 / 63
And yes, angle- and light-dependant, it is not easy to read the correct time or the printing on the dial.
Here are some pics - enjoy!
