I am speechless with the Resonance. I have only seen it once at an AD and once on another gentleman's wrist and I'm still fascinated by it.
In my opinion, although I love all the offerings by FP Journe, I still think the Resonance is the most unique piece by FP Journe. To me, this piece is the icon of FP Journe; like the Reverso is to Jaeger and the Royal Oak is to AP.
