Audemars Piguet Replica Watch Royal Oak Double Balance Wheel Openworked 15407OR.OO.1220OR.01

Audemars Piguet has been quietly killing chronographs for years. This watch is numbered 15407 Royal Oak Double Balance Wheel Hollow. It is the latest model among many innovative technologies proposed by AP. It can only do better and tell the time more accurately-they are already in the exquisite Hollow Royal Oak. done. how about it? Well, the name of the watch may give you a hint-the RO has two balance wheels.

The openwork Royal Oak has been around for many years, but the founder of this line may be 15305 in 2010. Then, in 2012 and 2014, we saw the traditional 39mm oversized jewellery got “openwork” in platinum and rose gold. Now, for the first time, we have seen the current 41mm Royal Oak, the reference number is 15400 hollow, but it is equipped with the world’s first new double balance wheel escapement system!

Now, AP has produced some very high-end watches in the past. These watches use two hairsprings but not two hairsprings. They include millennial and millennial minute repeaters with AP escape devices. The idea here is that having two balance wheels will produce a larger mass oscillator, thus ensuring high stability-for example, why would you see a huge oscillator in a marine timer. In previous watches, the two balance springs would counteract the effect of gravity on the balance itself. Basically, every time the balance spring contracts, it pushes the side of the balance toward the side of the top gem. This extra friction affects speed and depends on the position of the watch. Theoretically, the double balance springs should also offset each other’s velocity errors in the vertical position.

This new Royal Oak is further developed, in fact not only has two hairsprings, but also has two complete balance wheels. As you can see above, they oppose each other and should not only provide greater quality, but also oppose each other for self-regulation. Very cool.

Now, another thing this watch offers is true high-end hollowing and component finishing. The entire movement is completely hand-made, and the inner corners we see on the entire movement are the product of human hands. Like the latest open RO, the 15407 has an amazing dark gray dial and gun-colored metal treatment, making the entire look more gorgeous and ancient than the traditional hollowed-out watch. The Golden Balance Bridge lets you know that there are some special things there.

The Audemars Piguet royal hollow double balance wheel has a diameter of 41 mm, thanks to the ultra-thin 5.57 mm 3132 movement, with a 45-hour power reserve. It is available in stainless steel and rose gold.

Audemars Piguet Royal Oak double balance hollow watch hands-on

The Audemars Piguet Royal Oak Double Balance Skeleton Watch (shown here for the first time) is the first time I was attracted to at SIHH 2016. AudemarsPiguet provided a series of dazzling truly messy new watches at the exhibition. Of course, its iconic Royal Oak series was also well received. A lot of attention comes in the form of very high-end new models. However, one of the few Royal Oak watches made of steel is quite high-end in the Royal Oak Double Balance Wheel Skeleton Movement-of course, it also uses 18k rose gold.

When I debuted the new Audemars Piguet Royal Oak Double Balance Wheel Openwork series with the brand new self-made 3132 self-winding movement, I did not have a very critical message. This information is actually the accuracy of the “double balance” concept developed by Audemars Piguet to improve the stability of the regulation system. Audemars Piguet has been looking for a way to reduce the impact of reduced accuracy caused by the natural tendency of the balance to change its performance according to various variables. All changes from the position of the wrist to the temperature will cause subtle changes in the way the balance wheel works, which will greatly affect the accuracy over time.

The holy grail of any mechanical watch movement manufacturer should have a completely firm and stable adjustment system that is not affected by environmental changes. Of course, this is practically impossible in a clock worn on the wrist in various situations, but a system that can improve rate stability and increase accuracy over time is possible.

Therefore, the brand claims that the 3132 caliber movement of the Audemars Piguet Royal Oak Double Balance Wheel Openwork Watch is 30% more accurate than similar movements without this system. This is not a trivial performance increase, and lovers of accuracy (and Royal Oaks) may flock to this beautiful concept. Of course, Audemars Piguet may just hide this new system in the case, or it can only be seen on the case back, but they become a “complete skeleton” to show off its new movement with pride and fashion. .

The operating frequency of the 3132 self-winding movement is 3 Hz (21,600 bph) and the power reserve is 45 hours. The movement is made up of 245 parts and debuted in the form of an exquisite “openwork” with a gorgeous rose gold balance bridge. The novel concepts of the movement are all “double-sided” balance wheel structures. The center rod (pinion) connects the balance wheel to the hairspring structure. The two balance wheels are connected, but technically operate independently. They “average each other” (so to speak), believing that the accidental error of one will be compensated by the “more real” operation of the other.

The balance wheels are actually very close to each other, so if you only look at the movement of the movement without knowing what to look for, you may easily miss the whole special concept of 3132. In many ways, it operates like most other sports, but has a more stable (converted to accuracy over time) regulation system.

Audemars Piguet performs the finishing of typical high-end decorations and skeleton movements. The result is beautiful, and the slightly reduced readability can be easily forgiven compared to a hard-dial Royal Oak replica watches online. Having said that, the rose gold hour markers and matching hands are completely complete. In addition, even if there is no official power reserve indicator, the main barrel is hollowed out. By allowing people to see how tight the spring is, it provides a rough power reserve indicator system.

In order to maintain the modern style, the bridges of the 3132 movement are mostly in dark gray tones and are finished with very traditional surface treatment techniques (such as edging, brushing and polishing beveled edges). The movement is masculine, but traditionally beautiful, with a good mix of colors, hues and areas to be noticed visually-not to mention a good aesthetic balance.

According to Audemars Piguet, this is actually the first 41mm-wide Royal Oak case with a hollow dial. Having said that, this is not the only 41mm wide Royal Oak Openworked (openworked) watch in 2016. In steel, Audemars Piguet Royal Oak Double Balance Wheel Openworked is very meaningful, but in 18k rose gold, it is a completely different watch. Speaking of gold, it is important to mention that Audemars Piguet is really trying to use 18k gold as an option for Royal Oak watches this year. Sometimes it is difficult to determine the difference between gold on the wrist and pink/rose/red gold, but the difference between the two types of gold is very obvious.

Considering the metal content in the Royal Oak case and bracelet, the price difference between the Audemars Piguet Royal Oak double balance wheel hollow stainless steel and rose gold is certainly not insignificant. The Royal Oak with a skeletonized dial is completely different from the Royal Oak with a more traditional “Mega Tapisserie” dial-therefore, this artistic dial treatment makes the overall composition of the watch very distinctive, even for those familiar with wearing it. Words Royal Oak Watch.

Compared with the “standard” Royal Oak automatic winding movement of the 3132 movement, the performance is improved by 30%, which does increase the attractiveness of enthusiasts, because, although Audemars Piguet does not often introduce new movements, it rarely does Introducing a new “simple” or daily wear movement, orienteering. Therefore, in this regard, 3132 is even rarer. There are many great new best quality replica watches at the 2016 International Watch Fair (SIHH), and Audemars Piguet Royal Oak Double Balance Wheel Skeleton Watch is particularly outstanding because it combines the appeal of hardcore watch enthusiasts with pragmatic innovation. The stainless steel reference price of the Audemars Piguet Royal Oak Double Balance Wheel Skeleton Watch is 15400ST.OO.1220ST.01 (steel), while 15407OR.OO.1220OR.01 (18k rose gold) is a refined watch.
