The hand has likely drifted slightly on its pipe or the pivot it is fitted to.
Since you literally just got it you should be able to take it back to the store and either figure an exchange, or get it sent back to Breitling for repair.
I know it sucks especially since you just got it, but having someone else open it and attempt to repair the hand could end in disaster and ruin your warranty.
