I've noticed that when I wind my Aquis, it does not wind smoothly. It almost feels..grainy. Not sure how else to describe it. I'm about to send it in for service due to a tight rotor (2nd time!), and want to know if I should raise this issue (again). The first time it was in for service, they said it was fine, but it definitely does not feel like my other Oris (TT Diver) or Omega PO. Thanks in advance for the input!
