A good thought-provoking post, Mitch! [nt]
A great way to kick off the new year!
A few innovations came to my mind:
- the magnetic pivot Breguet developed in 2010; first presented in Reference 7727
- original oscillator in Zenith Defyn 21 Lab (2018)
- constant force escapement from GP (2013)
I'll keep thinking.
