Beautiful watches! I believe that Rydis Silva also makes a resonance watch although I have not seen one in person.

Few additional points - the chronometer resonance does work in vacuum despite claims to the contrary by some. Experiments confirming the effect were initially done by Breguet and of course by F. P. Journe himself when he was working on his design. For years he didn't talk much about his research, I guess sustaining the mystery and controversity around the chronometre resonance made sense from marketing perspective In case of doubt, the effect was also independently confirmed by Giulio Papi.

Dulaity, GF double balancier, Mb&F HM2, various RD models, are not based on a resonance ; In fact in the presence of a differential the oscillators should be independent of each other so having a resonance effect is not desirable.

A pair in Resonance.

As best as I know there are four watches in the market that are said to have Resonance movements. Here is 50% of them. The Armin Strom and the FPJ. The Armin Strom utilizes a clutch spring to keep the two movements in Resonance. A truly magical piece. Fas...

Here is the interview, he says a lot of interesting things!

He mentions a new design for the resonance

In other interviews, he has mentioned a new design for the chronometre optimum, and some sort of watch with an unnamed astrological complication.

Really interesting to see a side by side shot of these two very unusual timepieces and complication

I couldn’t imagine that the case size difference could be so big between the Armin Strom and the FPJ 😳 But I particularly love the complementarity of these both watches. The FPJ is dressier and formal while the AS points out the technical nature of this c...

Fascinating subject for me

Like you said there is the FP Journe Resonance, Armin Strom and Haldimann H2. It is indeed a very rare complication. I am not sure if Rudis Sylva version is a resonance though. From what I understand, the two balance wheels mesh with one another. It sound...
