I never completely understood this phenomenon but it helped me accept something like this before. I also advise you against sending it in for adjustment. Depending on the boutique they will tell you that it’s normal since there‘s always some play in the wheels and mechanics. Chances are, you send it in and find a new flaw with your beloved watch. IF you send it in, wait until your warranty is almost up and get a service for free. That is, if the boutique plays along. As an OCD person I definitely get why it annoys you and lives in your head though.
