Ah, sorry for the vague comment
Just that watches with two separate balances, resonance or not, still average the beat rate through some sort of mechanical differential. Even the FPJ resonance when the balances aren't in resonance the watch is still taking the the outputs of each and averaging them. So, I wonder whether the resonance effect has a real world impact on accuracy above and beyond just the mechanical averaging of two balances through a diff. Dufour Duality, MB&F HM9, GF Double Balancier, Czapek, etc all claim increased accuracy from having the average of the two balances. Just worth a discussion. Could also be worth investigating whether two balances really is greater than one given the difficulty of timing a watch with two balances, the increased power need, and the increase in drivetrain loss with the added differential.

Resonance and its properties, any insight welcome
Hello, I am a Journe enthousiast from London. I have been reading and not participating much so far. I have been facinated by resonance trying to understand it further. I enjoyed this talk FPJ gave at the NYHS a few years ago being able to speak a little...
Some math words beyond me
Some of the math was over my head but I think I understood in principle, he thinks if the balances are close enough (+-5 s a day) and in a cycle you could tell a story to say they are in resonance and if they are not blame outside interference but soon re...
WOW
this was excellent and touched on some many makers. The video is very hypnotic, I had to show my wife who seemed unimpressed I was showing her a table of Metronomes and trying to explain how its like what happens in a watch that contains 2 dials from a br...
could you explain it more please?
Thanks for contributing, I am afraid I don't understand what you mean. Probably my understanding is to limited. Could you say it again in a way you might explain it to a child? I would appreciate it a lot as I am sure what you said is relevant to the disc...

I think you may be mistaken...
The escapements are not connected in the joure (as they are in other examples you mentioned). The journe has two separate second hands with nothing but the vibrations of the main plate connecting them. There is no "averaging" happening with the journe. Se...
Thanks for continued input
Not at all bothered if you doubt resonance in FPJ watches. I still feel like I'm learning even about other double balance watches and how they work. Out of interest if I understood correctly you do think resonance occurs when the balances are linked like ...
I'll do my best to answer you...
1) Out of interest if I understood correctly you do think resonance occurs when the balances are linked like in the Armin Storm but not in the FPJ because the lightness of the balance spring is so tiny Vs the mass of the main plate so the idea the vibrati...
Great Answers thanks
Lots to agree on, Thin watch I think wears nicer on the wrist and i prefer the presence, not sure if its the curved bars connecting the strap but when I tried a CS in the boutique was very nice on the wrist there but easy to forget as well. (and I have pr...
"Ill ask the FPJ boutique next time I'm in for you if they can put you on the list for the flat white dial CS if they ever do it in 38mm again, maybe some time on the wrist will warm you up to Journe wink"
Thanks, but that's a haaaard pass for me! As for the resonance running on magic, perhaps I used the term wrong. I did not mean "magic" as in what ancient people believed was the cause of lightning because they lacked understanding. We well know how the pr...
A warm Welcome to WPS , Digby
I hope you will enjoy our forum. The place is full of passionate collectors and sometimes with passion opinions can get strong in this place. I want all members here to make Digby feel welcome! To your excellent question regarding the Chronometre a Resona...
Hear hear! Please feel welcome here, Digby.
BigFatPauil is our resident Journe-hater, who probably should have picked a better time rather than risk having a new person feel unwelcome.
Thanks Christian
plenty for me to get stuck into, and a superb example of your Resonance! I will also revisit the Art of Breguet and try not to get down a rabbit whole on pocket watches subsequently!
I don't mind Spangles but he seems often upset at me :) The vast,vast majority of members here are really friendly.
All I did was post a link - I didn't express a personal opinion. I think people come here to get all sides of a story, and giving all members is a welcoming thing. It would be bad if new members thought there was Kool-aid on the menu, right? It would also...
Thanks both :)
I am happy to understand opposing views on the subject, I think in order to have any hope of understanding it I should understand/ read opposing views on the subject. I didn't realise until posting there were varying opinions on the 'realness' of resonanc...
double balance openwork royal oak right?
I have often thought it interesting that this is never cited as a resonance watch, I think because they are on the same balance staff/ axis so is enhancing the mass of the oscillator to improve accuracy as less easily disturbed and going in opposing direc...
