I know it's sarcasm
He's finding all those great grail watches, like the Pan am Daytona, the white albino explorer, one of a kind A 6538..... Back in the days (not so long ago) he had a watch shop in Holland, Steiner!
The all known Vintage Guru sold milsubs with Omega sword hands, so called fake Comex watches he bought on the bay for nothing and sold them for 10.000€, etc...
You can read a lot more about him on the Dutch fora.
I have a nice story from my personal experience with him. Avoid the vintage Guru/puppet player!
