Double balance skeleton watches belong to the larger category of general purpose Cheapest Audemars Piguet Replica with two balances. Generally, they fall into two basic categories. The first are the extremely rare resonance watches, where the two balances are mechanically coupled in some way so that they influence each other’s beat rate and eventually start beating in sync.
The second group are double balance watches, where two or more balances are connected via a differential. The classic example is Philippe Dufour’s Duality watch. Dufour told me that the Duality is designed to take the Best Audemars Piguet Replica Watches average rate of the two balances, one of which he adjusts to run slightly faster and the other slightly slower.
Since the watch is in different positions relative to gravity throughout the day, the positional errors should cancel out and, at least in theory, you should get a better rate than with a single balance. Many watchmakers and brands have tried this solution since the advent of Simplicity.
However, the solution Audemars Piguet First Copy Watches has adopted in the Royal Oak Double Balancier is unique, as far as I know. Instead of two or more independently oscillating balance wheels, the Double Balancier has two, but on the same balance shaft and therefore on the same axis.
The superimposed balance wheels each have their own hairspring with opposing attachment points. The idea here is that, firstly, the effects of gravity on the balance wheels should cancel each other out due to the arrangement of the balance springs, and secondly, the two balance wheels essentially double the mass of the oscillator, which in itself means better resistance to rate variations due to external disturbances.
There are Newest Top Quality Audemars Piguet Replica with double balance springs, some of which are quite exotic – the H. Moser & Cie. Straumann Double Balance Spring is an example. But the Double Balancier is the only watch I can recall with two balance wheels on the same axis, both driven by a single escapement.
While this solution has many theoretical technical advances, it has one small drawback: a lower power reserve due to the extra inertia. Running at 21,600 vph, the power reserve is reduced from about 60 hours to about 45 hours.
If you ask me, though, 15 hours of running time is a small price to pay for the beauty. I think the combination of skeletonization and the double balance fits the design of the Royal Oak perfectly. The Royal Oak Replica Buy Now is a classic for a reason – the design was truly revolutionary at the time and has remained admirably so in the decade that followed.
But for some reason, the gorgeous vintage art of skeletonizing the movement seems to fit in perfectly with the surrounding octagonal bezel. I think traditional skeletonization on its own can be too fussy, while the Audemars Piguet Replica Watches For Discount would be too rigid if left alone. However, the combination of the two complements each other so well, and the double balance adds a little unexpected magic to the combination, it’s a match made in heaven.
