Audemars Piguet replica has been quietly killing chronographs for years. This watch is numbered 15407 Royal Oak Double Balance Skeleton Watch. It is the latest in a number of innovative technologies proposed by AP. It can do nothing but display the time better and more accurately-they are already in Made it in the exquisite hollowed out Royal Oak. 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, we saw in 2012 and 2014 respectively that the traditional 39mm oversized jewellery was “open-carved” 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 fake watches in the past. They used two hairsprings but not two hairsprings. They include millennium millennium and millennium minute repeaters with AP escape devices. The idea here is that having two balance wheels will produce a larger 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, whenever the balance spring contracts, it pushes the side of the balance toward the side of the top gem. This extra friction affects speed and varies depending on the position of the watch. Theoretically, the double hairsprings should also eliminate each other’s speed error in the vertical position.
This new Royal Oak goes further, in fact not only has two hairsprings, but also has two complete balance wheels. As you can see above, they are set relative to each other and should not only provide greater quality, but they should also fight each other to adjust themselves. Very cool.
Now, another feature provided by this watch is true high-end hollowing and component finishing. The entire movement is completely finished by hand, and the inner corners we see on the entire movement are the product of human hands. Like the latest open RO watch, the 15407 has a stunning dark gray dial and gun-colored metal treatment, making the overall look more gorgeous and older than traditional hollow watches. The Golden Balance Bridge lets you know that there are some special things.
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.

My love for the ultra-thin Royal Oak (known as “mega”) is well documented. This is my first truly high-end watch, and I do believe that it is not only one of the outstanding designs of the 20th century watchmaking industry, but also perhaps the most balanced watch ever. The way it sits on the wrist? what. That’s great. So, although the focus of AP this year is the new 42mm Royal Oak Offshores, my personal highlight in the new version is a new attempt on Jumbo.
The Associated Press’s hollow tactics are some of the best, and we rarely see them suitable for Le Brassus manufacturer’s purest watch Jumbo. In the past few years, some limited edition extremely gorgeous Jumbos skull watches came out, and then in 2012, we made a new attempt on the skeletonized Royal Oak, this limited edition 40th anniversary platinum watch. The watch is amazing. Nevertheless, it does not have more vintage APs than the hollowed-out Jumbo, and I always think this is a watch they should use more accessible metal to produce. This year, they adopted the new solid rose gold version of the ultra-thin Royal Oak Openworked to do just that.
From both sides of this new RO, you can see the process of AP’s skeletonization of the 2120 movement, which has been hollowed out in slate gray and is called the 5122 movement. The appearance of this watch is spectacular. Of course, this watch retains the perfect size of the 15202 giant watch, so you are looking for a 39mm case with a thickness of only 8.04mm.
The new rose gold hollowed out ultra-thin Royal Oak will not be a limited edition, but will be produced in limited quantities every year.
