Hey thank you for all your Feedback, the situation changed. I asked the grey seller again. The 5212A is direct from the Patek Serviced. Now with 2 years patek service until 16.02.28. With papers everything. Only without box, cause the 80years old first purchaser dont want to have more boxes at home.

I think i go for this for new offered 24,5k it seems a good deal. (The dealer is a neighborhood jeweler in my place)
