The Crown has begun getting stuck in place after a time adjustment and will not easily push back into the movement.  Also will not pull out of the movement to allow for a time adjustment without difficulty.  Since this is a skeleton watch I can see inside that there is a piece making contact where it should not when I try to push in the crown.  Even when brand new the manual winding has been very difficult.  the is my 2nd Rio watch and the mechanical behavior of this watch is not the same.  

Thank you.
