One of the boldest pieces in the Royal Oak collection, along with the classic 15400 and ultra-thin 15202, has been the Openworked Selfwinding version 15305 – so it’s a connoisseur’s watch designed for collectors who care about watch making and collecting. Who knows how to identify real advanced clock execution and decoration. This watch USES 39 mm watch case, use famous machine core 3120 evolution, use completely hollow-out version, complete in an excellent way: the Angle of manual execution, multiple inside and outside angles. However, in 2016, Cheap Audemars Piguet Replica decided that the watch should be updated by introducing a new Royal Oak double balance wheel hollow reference 15407. Why would they do that?
First, the new Openworked version updates its case to 41mm in diameter, consistent with the rest of the “automation” series (understood here as 15400). But that’s not the main evolutionary point. Most impressive is the addition of a second filament to the 3120 core’s regulating mechanism. What are the advantages of this feature? There are different points of view to consider. The first is about visual pleasure. There is a double pendulum wheel, one of which is placed on the side of the Audemars Piguet replica watches dial, so that the wearer can appreciate the ballet of the organ even if they are wearing the watch – and watch the movement.
However, the major upgrades involve technical aspects, primarily timers. Compared with the traditional “single balance”, the advantages of this dual-wheel device can be measured correctly by placing it on the classic 3120 core. The idea is to take advantage of the advantages of two equilibrium springs, without the problems that come with them. Double spring can improve the precision. However, this structure (when you have two threads on the same side of a single balance) is known to be difficult to adjust and generate additional friction on the balance bar. In the escapement mechanism with a spring, an error occurs because the spring is connected to the point of the bolt. One solution to this problem is the Breguet terminal curve (which solves this problem nicely). Another effect is your error in the spring alloy. Use made of the same alloy two spring and separate them 180 ° completely canceled it, this is helpful to Audemars Piguet Copy watches the whole time performance.
The idea of double balance instead of double filaments means a structure with a balance bar, each side with a cycloidal wheel and a filament, that can adjust the Fake Audemars Piguet Watches from each side of the movement. Because there are two variable inertial balances placed relative to each other (each adjusted by eight inertial blocks/masselottes), this means that the weight is perfectly distributed around the balance bar, and the watchmaker can adjust the watch with extreme precision in all positions. In addition, since the weight on both sides of the balance bar is equal, this means less friction and better distribution – explaining the advantage of double balance over double filaments on a single balance.
