He used to be one of the top watchsellers for vintage watches in Germany (located in Köln or Düsseldorf), he also had frequently Watch auctions (old auction-catalogs are available via his pages) he is located on the Baleares, (Spain) now,
guess he was fat up with the rainy autums/winters here in Germany. I personally watch his Heuer Offers from time to time, exept some franken-Carremaros, he seems to offer excellent stuff, would reccoment to verify the ref# engraving on the case, to make sure all is well.
