Got this watch (SPB253) not too long ago and just wanted to check the wear on the crown tube threads so far and noticed a part of the threads are "flatter" as if they had been cross threaded (Image with the blue background, threads on the right circle are flatter than the left). Second Image is what the flatter bit looks like when looking at it straight on. I'm inclined to believe this is a factory defect as the PVD coating is not worn off on that part, but I'm concerned that the threads...

Help! Are these threads ok?
