Wow, this is amazing news. So nice to see that mechanical watches can and will develop. I am not 100% sure I would like to listen to the 40 Hz buzzing of the oscillator, but the improvement is amazing. Price-wise it is also very reasonable. It is good the Frederique Constant did it and not, say, Zenith or Omega, prices are much more reasonable. Once the technology is ripe in a few years, I will be certainly interested. Kudos Frederique Constant and collaborators!
