Recently picked up a gorgeous U50 and as with other Sinn's I have owned this one suffered from bezel alignment issues but fortunately just as before the fix is relatively simple as Sinn engineers adjustment into the case. The bezel is captive so removing it only takes backing up the 3 screws on side of bezel to remove it. Just be careful not to remove the screws all the way as they are small and can easily be lost. I was expecting a ball bearing system under the bezel but to my surprise its a "multi" point click spring, had never seen one like this but it explains the super solid bezel feel. Once spring is removed there are multiple fine tuning holes where spring can sit in order to adjust the location of bezel click. In my case I had to rotate two holes clockwise for a perfect alignment. Hope this helps other WIS out there that suffer from OCD as me. Oh and btw just for giggles I contacted Watchbuys and sent photos and as expected was told bezel appeared to be within tolerance. Pics tell the story better so here you go
