Here is a curious one! It came my way today for possible repair. It was stopped, and fully wound, It had two trade marks that I could see, on the movement. One on the pillar plate, and one on the train wheel bridge. I looked up both trade marks in Mikrolisk, and got a hit for each one. Well, sort of a
hit. The Mikrolisk entry on these two trade marks were either not identical, or otherwise, vague! So I pulled the dial. Voila! A definite hit! The watch was made by the International Watch Co., Schaffhausen, Switzerland, I have shown numerous images of these trade marks, but the only one that is relevant is the IWC one. The IWC trade mark shows in Mikrolisk as
PROBUS IWC SCAFUSIA which clearly shows in the one picture.

The movement is in excellent condition, and it shows many of the earmarks of other high quality Swiss watches. The one trade mark inside the case back indicates .925 (sterling), and one other trade mark indicates the case was imported into England from Switzerland. The hunter case is known as a Demi-hunter, of half hunter. Because of the window, you don’t need to open the case to read the time. Hence the curious hour hand.
The reason it quit is that one of the case screws had come out and was buried in the gear train. I coaxed it out, put the watch back together, and left it running. It should be cleaned but I’ll call the dude and see what his pain threshold is like!
