My U1 has a very small scratch on the crystal -- very, very small, but it really bothers me. I contacted RGM (Sinn's authorized US repair center) for a repair quote. They told me that the watch had to go to Germany for a replacement crystal, and the price would be $245 plus $40 shipping. That sounds like a lot for a new crystal (hell, I think that's about what Rolex charges for a new crystal!). Any suggestions?
