So I have a new Datejust 41 and at the begining the rotor was completely silent. But after 7 days it's started making some noise. It's like the ball bearing is making some “rolling” noise. It really annoys me and I went to the AD with jt. He said it's normal for the balls to make a sound and if I want I can send it to Rolex. Should I send it in because it really annoys me. The only thing that is keeping me off from sending it in is that ist has perfect time keeping ( +0,2 seconds a day ). Will it be still the same afterwards?
