40Hz Silicon Oscillator
While I have a deep appreciation for bi-stable mechanisms & admire the pioneering work Flexous has achieved with this new oscillator & escapement for Frederique Constant, I think it's a mistake to show it off through an aperture in the dial.
There is something humane & almost soothing about watching a mechanical timepiece tick away at rate of five to eight times per second. Witnessing the oscillator vibrating a literal order of magnitude more than that every time you look at your wrist is going to feel downright unnerving.
