there are still RG models available. The price for the WG is even steeper, and many people are going to be reluctant to spend that kind of money for a Sinn. I do not think you will have to rush to see one or get one.
But I think those who say "Sinn? Too much." are making a mistake with this watch. It is well-done and has a German movement created by Marco Lang. it looks to be great value.
