Scatches on new watch movement

[RBR76]

I got myself a Tag Carrera from AD yesterday.

To my surprise, i found a scratch on the most unlikeliest of places - the movement - seen clearly through the watch's glass caseback.

I was quite disappointed cause i have been wanting to get this watch for sometime.

I gave my AD a call and returned the watch to them. They say that this is the first time that they had seen this.

I will need to wait for about a week and the likely remedies - refund, new watch or service centre to fix the problem.

Any similar encounters or thoughts on this?
