Audemars Piguet

A new 41mm Openworked Royal Oak features a newly designed double balance wheel said to improve precision and stability. Much more to follow on this exciting new world-first model!...  

and I'm curious to see what is the principle leading to this double balance wheel feature and its improvements. Thanks Michael. Cheers, Mark

due to two wheels moving opposite direction thus cancelling out movement error of each other? I think. more to be unveiled soon, I suppose.

Looks good, I really like the precious metal version. Just wish it was in 39mm case vs the 41mm. But will definitely have to handle in person to get a better overall view. Can't wait to see live photos. Regards, ED-209

Probably the best release of AP this year. I have the RG version of 15305. Should I upgrade?

I'm not denying the new model is not exceptional, but 39mm of colored gold is plenty for me. If I did anything, I would add the steel model. I thing gold hands and hour markers are a great visual improvement to that version.

. . . the steel 41mm open-worked is winning my heart over. I'm excited to learn the price point of this piece. M4

Not inexpensive, but not outrageous either.
