Audemars Piguet Audemars Piguet Royal Oak Double Balance Wheel Not Only Frosted Gold Case But Also Rainbow Gem Bezel

AUDEMARS PIGUET launched the Royal Oak Double Balance Wheel Openwork in 2016, creating a new realm of similarly designed watches with a rare vertical series of double balance wheels. In recent years, brands have also been targeting this. The 3132 movement is carried forward. In addition to the original 41mm extended frost gold and white gold case or platinum diamond bezel, AP also launched 37mm models with smaller diameters, including platinum frost and rose gold models. In 2019, the Royal Oak double balance 37mm style has evolved again. This time, Audemars Piguet combines the existing white gold frosted gold case with the colored gemstone circle concept of the RO automatic watch in 2018 to form a new frosted gold rainbow circle. The rainbow circle design introduced by the altar has more and more phenomena, but in terms of the special features, the Audemars Piguet balance is still one of the best.

The frosted gold case is already very visually attractive. In 2019, Audemars Piguet will set up as many as 32 colored sapphires on the bezel. Each diamond has a different color, forming a visually clever gradient.

Feature one: Frost gold and rainbow circle combined attack
Frost gold technology is a case decoration process jointly developed by AP and Italian designer Carolina Bucci in 2016. This technology uses diamond-tipped hammers to strike precious metals and form fine dents on the surface. The reflection of light emits a twinkling light similar to that of precious stones, and it also brings the Bling-Bling effect like setting diamonds in the case. The original frosted gold case was more exclusive to women’s watches when it was first introduced, but after several years of hardening, this technology can now be found in works with larger watch diameters that will be considered male watches. Although the diameter of this Royal Oak double balance watch in 2019 is a neutral 37mm, frosted gold technology has also been applied to this watch before, but this time the brand set another 32 colorful rectangular cuts on the bezel. The sapphire and precious stones on the bezel weigh 2.24 carats. Together with the shiny frosted gold case, this watch’s visual gorgeousness climbs to the peak of the Royal Oak double balance watch.

The positions of the balance springs of the double balance wheel are opposite, and the two balance springs move in the opposite direction during the shrinking process, so as to offset the errors.

Feature 2: Similar concept to double hairspring
The double balance wheel system has two balance wheels and two balance springs, but the escapement still has only one set. The actions of the two sets of governors are completely synchronized, so there is no concept of differential speed integration. The benefits of the two sets of governors are mainly to increase the swing inertia-it is reported that this system can increase the overall swing inertia by 30%, and theoretically a larger swing inertia means higher accuracy, which is the system’s The basic logic is, to some extent, an upgraded version of the double hairspring system. At the 8 o’clock position of the hollow face plate, two balance wheels arranged vertically can be seen. The positions of the hairspring piles of the two balance wheels are opposite to each other. Therefore, during the contraction of the hairspring, the center of the circle will move in the opposite direction. Cancel the error caused by the displacement of the center of the circle, and achieve the goal of improving travel time accuracy.

The 3132 movement is based on the 3120 movement. In addition to the newly added double balance device, its hollow design and increased movement thickness

Feature three: Reworked 3120 movement
AP’s double balance device is based on the 3120 movement, which is derived from the new 3132 movement. In addition to the significant difference between the two movements, whether the 3132 needs to accommodate the vertical double balance, the thickness of the movement has also increased to 5.57. At the same time, because the double balance wheel needs more power to drive, the movement storage space of the 3132 movement is reduced to 45 hours.
