SIHH 2016: a wristshot of the Royal Oak Double balance wheel openworked
This watch is in my top 3 of the fair. A superb work by AP and the enlarged case is fine here thanks to the movement lay-out and the strong presence of the balance bridge.

Something about constant differential
Greubel Forsey presented something similar..
"This new mechanism redefines the limits of timekeeping. Two inclined balances optimise performance in a stable position, while a constant spherical differential provides more steady amplitude."

No, sorry, it is not the same system. There is no differential on the AP. [nt]

To improve the stability of the movement operation.
There is no differential here nor resonance effect. The idea is to make the balance wheels oscillations more stable even in vertical position. We have here two balance wheels and two hairsprings and the objective is to make them auto-regulate.
It is NOT the same system seen in the Millenary Quadriennium or with Moser (two hairsprings only).

Thanks for the information. Now, I would like to understand how efficient it is. [nt]

Spoke to Giulio Papi
The two balances are connected in solid, so the turn and behave simultaneously.
Just a double wheel connected with a longer pinion.
The effect is that the friction is reduced and it has a beneficial chronometric effect.
No resonance here.

Need more photos but I think that...
the fact they are bound together means that any external influence affect the chronometry. they should accelerate or slow down simultaneously. still trying to figure out where is the improvement
For a second I thought "wait a minute..."
"..ooh the bezel "screws" are changed! There's a stepped circle in the middle now that looks funky- oh wait, its just the plastic protector. I'm dumb"

eh eh, you are right, the plastic protector gives this feeling! ;-) [nt]

I was about to ask what happened to the screws.
Luckily i found your post saving me from an early morning, eyes half open, mistake.
New AP
How legible is it? It's no doubt a stunning piece, but I would have hoped for the movement parts between 6 and 9 o'clock to be of a different color to allow for a better contrast with the gold hands. Hope to see it in the metal later this year.
availability?
Does anyone have knowledge when these will become available for purchase?
how does it look hand on without any index on 12?
from the look of a picture, it seems like there is too much space without an index at 12.. This message has been edited by kunmoo on 2016-01-28 15:31:14
