MBW EOD with ETA7750 landed yesterday and I almost buggered it up on day 1. The 30 min subdial was not advancing past 1 min and would stop the movement, rotor was contacting the caseback, pushers were sticky, and crown rubber was loose. I fixed it all and when recasing the movement the stem would not go back in to save my life. I had to put it away for the night to calm down and take another go next morning with a clear mind and some coffee.
With a few more attempts of finesse, force, swearing, and a bit of luck, the stem went back in with no apparent keyless works issues
chronos function, rotor is silent, and crown rubber is secure.
Ziggy lume is a real masterpiece. Those of us that were around to see his work will appreciate this
