Horological Meandering: Surprising FPJ is that high

I've always associated them with horological innovation and design aesthetics, and would have placed their finishing more at the level of patek than Lange and Laurent Ferrier.

Automotive: Not sure what the use case is

... It only generates 43 miles of range per day, so if you want to go without charging, going 60 mph it'll net you about 20 more miles of range on your drive. If you're just using it intermittently, then you have plenty of time to find a place to plug it in and put the solar panels on a building's r

Patek Philippe: The star

Makes me think of sea-gull :P

F.P. Journe: 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 affect synchronization after many periods (which

F.P. Journe: To be honest,

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 balances are fast or slow... Ideally you wou

F.P. Journe: The balances are fixed in relative position to each other

So translational movements such as "slightly nudging the watch" as you say will affect both equally. The movements which will act significantly differently on the wheels involve rotations about a center which is close to one balance wheel. The distance from the center of rotation to the wheels also

F.P. Journe: I imagine it will decrease variance

From factors caused by differences between individual balance wheels/springs such as manufacturing and setting imperfections, but not those caused by factors affecting both wheels equally such as position on the wrist... Unless perhaps Journe designs a resonance with orthogonal balance wheels...

F.P. Journe: I think without some serious calculus

You would not be able to provide a proof of concept. That is, I don't believe that a proof of concept would be "simple", and I don't believe that a simple explanation would be "proof". That being said, I'm not a mechanical engineer but I would believe that the whole point of the setup is that the eq

F.P. Journe:

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...

F.P. Journe: 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 materials and techniques, or if it's currently
