How to understand that?
This is the only one that has the best silence rotor I have ever saw
There are lots of flaws which indicate this is a low-end replica.
E.g., the SEL (solid end links) are completely wrong, the fluted bezel angles are poor, the cyclops location is completely wrong, the lug shape, etc.
Unfortunately, major factories like CF and VSF that excel in making the Wimbledon (Datejust 41) are significantly more accurate than your watch. There are also various low-end/ obscure factories making low-end Rolex, which makes it hard to pin-point which factory is your watch from.
Also, the genuine 3235 movement does not have a completely silent rotor. The rotor is noisier than a 3135 movement.
