So what are the supposed technical advantages?
15 Hz frequency, better accuracy, and longer power reserve. While compared to a conventional Swiss lever mechanical watch, those are certainly advantages, they are 40+ years late. Tuning fork watches and later on quartz watches both exceed what this watch can do...tuning fork watches operate at 360 Hz, and a quartz watch is over 32,000 Hz (most quartz crystals used in watches have a frequency of 32,768 Hz). Both will have better accuracy than this, and longer power reserve using a battery, capacitor, or a quartz watch with a spring like the spring drive.
So in one way this is like creating a better buggy whip than the original, but still 2 steps back from the best buggy whip available. But this is the current way that many brands in the watch world are going. Omega co-axial is the same sort of thing, along with silicon balance springs in Rolex, AP using a different escapement, etc.
I guess for me the question becomes: How far away from a traditional mechanical watch do you get, before there is so little of the "tradition" left that you might as well just buy a quartz watch?
I don't have the answers, so just giving you my thoughts on this one...
Cheers, Al
