They are difficult to regulate because both sides need to be regulated to almost perfection in all 6 positions. That is hard in any watch.
From what I have been explained by a watchmaker a watch can be well regulated in 5 positions and the watchmaker can "hide" the irregularities in the 6th position. The Resonance is unforgiving in that way. you need regulating in 6 positions x 2 to be within a delta of 5 seconds. That is a lot of patience and work to get there.
That's very cool

I wonder if they're using any special materials on the mainplate to enhance the coupling... I'd expect something more rigid would be better? No doubt shape would matter as well... I guess I'm wondering how much this effect has been optimized with modern m...

Haha, looks like I would have to get a brass resonance to satisfy my optimization tendencies then! That's very bad news for my wallet though, I guess I'll have to stick with admiring my little CS for now...
There's a difference

This analogy doesn't necessarily work since metronomes in a car would have to be fixed to the car and even then there's a huge difference with resonance in a wrist watch. The effect of your wrist moving doesn't impact the vibrations of the oscillators in ...

I never understood why one had to be slow and one had to be fast. I've always thought the point of resonance to cancel out variances within the operation of each balance - to improve precision, not accuracy. Intuitively, that should occur no matter if the...
Thanks for explaining!

But this phenomenon makes me more doubtful. I would imagine the vibrational forces coupling the two balances together at the moment of impact would be orders of magnitude less than external shocks acting on the balances as they move, and so only would aff...
