The only problem with this watch I have so far is the noise. It sounds like a train sometimes.
But I was able to put some Molykote on the rotor bearing today and it becomes super quiet. The process is way simpler than I thought. Those three screws you see at the back are actually just fake screws, glued there for cosmetic purposes only. You can easily peel the whole center dish with the 3 fake screws out, then the real rotor bearing screws are under that dish. Unscrew them with a good tool and the rotor is out, turn it upside down and put some Molykote in, done.
