Audemars Piguet Royal Oak double balance wheel “High Jewellery”

Finishing and diamonds.

Combining the famous octagonal case and innovative movement watch, Royal Oak Double Balance Wheel Openworked is undoubtedly the most interesting time in technology. Audemars Piguet (AP) Royal Oak. Then there is this gem-like version, which is definitely more luxurious, but at the same time better shows the details and finishing of the movement.

initial thoughts
This watch is the ultimate black tie watch, only timekeeping and classic, measuring only 37 mm. In fact, it is much smaller than the 41mm standard model, allowing it to be carefully installed under the cuffs and possibly secured by diamond-encrusted cufflinks. It is also decorated with a smooth crocodile leather strap and a large number of large rectangular cut diamonds. This is a technically particular watch that takes its sparkle very seriously.

But this is not just another octagonal watch with diamonds. The movement relies on novel technical concepts to achieve better timekeeping, but due to its technical advantages, it is usually ignored because it is installed in a “hot” replica watches swiss.

Compared with the standard version, a special version of this section of the movement here to implement more attractive. Because the movement here is plated with silver rhodium-which undoubtedly matches the brilliant whiteness of the diamond-it is more attractive than non-jewelry with a dark grey ruthenium finish (almost black). Although the surface treatments of the two are basically the same, the dark surface treatment conceals many details of the movement, while the bright surface treatment reveals the effect of the surface treatment well.

Double balance
Cal. 3132 adopts minimalist timing principle, with two hairsprings, each hairspring has its own balance wheel. It is essentially a simplified version of the workhorse calibration. 3120, plus double balance wheels.

The two ends of the conventional flat balance spring are fixed, which means that the coil of the spring will be slightly off-center and stretch. When the movement is moving vertically, the problem is aggravated by gravity, which pulls the balance spring downwards or even off the center.

One solution is to pass the coil, which loops the balance spring back to itself, so that both ends are fixed in almost the same position. Another solution is a double balance spring. The dual balance springs reflect each other’s movement. Each balance spring is inversely proportional to the twin, and the error of each balance spring is averaged. H. Moser & Cie. Double hairsprings are often used in high-end movements, and Montblanc has also tried double-cylindrical hairsprings. Audemars Piguet Royal Oak replica watches

The Associated Press has enhanced this concept with dual balance wheels-each hairspring has one. Although each balance is conventional and its weight is the same as that of a standard balance, there are now two, which means that the cumulative mass is twice the original. This actually doubles the inertia of the regulator, and can maintain a more stable timing even in the event of a shock balance shock.

But the increased weight means that more energy is required to keep the watch running, which is why the power reserve starts to drop from 60 hours in the standard calibration. The 3120 with a single balance wheel takes 45 hours here. Although it is reduced by one-third, 45 hours is enough.

In order to ensure that the upgrade is conspicuous, the balance is fixed on both sides by a pair of sturdy red and gold bridges. This is exactly the same as the standard model, but I would prefer the platinum bridge to maintain the balance of the watch, which will better suit the color of the diamond and movement.

The movement is the same as that of the standard model, which means excellent. But due to the light color of the finish, the bevel and texture are more obvious here. This is true both on the front and back.

The shape of the skeleton is clean, the bridge frame is plated with rhodium, the top is brushed with wire, and the outline is outlined by a wide polished bevel

Due to the complexity of the opening, the bridge incorporates several sharp inward angles within the chamfered edge. Not all internal corners are sharp corners, but it is enough to illustrate the quality of finishing.

The case is 18k white gold, and the front of the case, bezel and crown are set with baguette-cut diamonds. It is only 37 mm, but it looks and feels slightly larger than it.

However, the case is indeed a bit taller relative to the diameter. This is partly due to the thickness of the movement, but also to the slightly higher bezel needed to accommodate the diamonds.high quality replica watches

At first glance, the case looks naked because there are no diamonds on the sides. But this actually makes sense, simply because it is the Royal Oak. Leaving some visible metal means that a key feature of the Royal Oak is visible, which is the impressive case decoration. Here, the brushed side of the case is located next to the polished bevel on the edge of the case, with a clear boundary between the two.

The Double Balance Wheel watch set with diamonds is suitable for occasions. The black tie best described as luxurious, it is bold and elegant. And the movement is technically reliable, making it a serious watch with a lot of flash.
