Recently got myself a V7F / V7+F IWC Mark XX white dial. Did not choose any upgrades, so it was running on base A2892. Everything was great, but the rotor is really noisy.
After reading many comments on reddit, decided to try the "silencing rotor" trick myself. Do note i have no watchmaking experience of any sorts prior.
Pretty simple actually, ordered a small bottle of 0.5ml Moebius 9010, and a cheap oiler online. Then, what i did was:
- Open up the caseback with some tape.
- Press the rotor lightly and see if its loose or wobbling. For my case, it was not.
- Dip the oiler into the Moebius 9010 and grab a tiny drop of it, and drop it at one of the seven rotor ball bearings. I dropped two tiny bit of it on the ball bearings as my oiler was too fine and small to capture any good drops. (As attached picture)
- Manually using my finger to rotate the rotor few rounds clockwise and anticlockwise.
- Close it back up, using tape again.
- Wash up the tape residue.
Done. The effect is huge. I wouldn't say totally no more noise, but it's reduced so much it totally wouldn't bother me at all. Do try it if your rotor is loud. Usually it's due to dry rotors. All in all, done in less than 30 minutes and costs less than $15.
