Klaeuse SK-293 with natural diamond

Last September, I posted about a brand called Klaeuse who were a mystery brand, but one that used expensive materials. Today's watch is my second Klaeuse watch and follows the standard set by the first model.

This is the Klaeuse SK-293-F. It is a 3 hand dial design with a quartz movement.  Instead of titanium, this has a stainless steel case in silver and gold. The glass is shaped with a peak in the middle, and the glass is designed to have 12 flat faces which make it catch the light (like the cut of a diamond). On the face, at the 12 o'clock hour marker is a jewel, and according to the text on the face, this is a natural diamond.

I still haven't found any more concrete information about the Klaeuse brand as I can't find their website. The watches can be recognised by the brand name (in lower case characters) and their logo of a castle shape with a tall central tower. One site I found suggests that they are made by Elgin USA and use Swiss movements, and that model had an rrp of ¥38,000 (potentially confirming it is an expensive brand).
