I'm really getting concerned about the overall quality of Sinn Watches. This is particularly true considering the current inflated prices of Watchbuys for theses watches. I have three Sinn's; a U1, 756 and an EZM. On the U1, the triangle lume on the bezel has come off twice and the crown has come off once when resetting the time. I had the 756 into RGM late last year (which took three months) to repair the frozen GMT hand and now the second hand has come loose and does not work. In comparison to other watches of similar price point such as Omega or Breitling I'm just not seeing these quality control problems. I was going to by a 556 for my wife who wants a men's mid-sized but I think I'll go another direction. Is anyone else seeing these problems?
