In modern watchmaking, many complications which were formerly hard to make (and therefore very expensive) are becoming gradually less and much less so. Watch manufacturers, driven by a desire to provide better value to customers (and more pressure to do so, as the purchasing boom of the early 2000s rates off) are increasingly taking advantage of industrial fabrication approaches to make complications like tourbillons and endless calendars cheaper than ever before. However there are still a few complications which resist this tendency — and among them is that the minute repeater.
Rather than becoming more and cheaper, nearly the opposite tendency can be viewed in repeaters — they’re becoming, increasingly, places where brands showcase their highest expertise, and at correspondingly high prices too. Among the most recent watches to drop into this class is Audemars piguet royal oak yupoo repeater supersonnerie replica watch‘s”Supersonnerie” — a second repeater eight years in the building, intended to offer a slew of technological improvements which AP thinks will make it nothing less than the best-sounding repeater in the world. (The term”sonnerie” is most frequently seen in reference to grande sonnerie watches, that strike the time in passing rather than on demandnonetheless, the term taken independently might also refer to a repeater, which strikes on demand. The usage of”sonnerie” here could be confusing, so we must explain that the Supersonnerie is a second repeater, rather than a grande sonnerie.)
A second repeater is a wristwatch that chimes the time”on demand” — which is, it rings the exact period when you let it. Typically, a repeater springs to action when you push a slip set into the face of the case. Pushing the slide winds a spring that powers the chiming operation. A classic second repeater will ring on two gongs: one lower in pitch, and one higher. The ring on the lower pitched gong. The number of quarter hours beyond the hour are signaled by a recoil on both the lower and higher gong. Along with the moments chime on the greater gong.
Inside every minute repeater is a complex system of gears, cams, and levers making the second repeater complication. The moment repeater complication basically operates by studying the time mechanically from the position of the hands and then chiming the time. The second repeater isn’t a new complication at all; it existed in basically its modern form by the time of Breguet.
Abraham-Louis Breguet was fascinated from very early on by replicating watches. In 1783 he made the first striking repeating watch to be worked by a gong as opposed to a bell, which was universally used until afterward. Initially directly, and mounted on the rear plate, then the gong evolved into a circular form, coiled around the motion. It had the benefit of radically reducing the thickness of striking watches, while at precisely the exact same time making the tone more clearer and harmonious. An exceptionally useful invention, it was adopted immediately by many modern watchmakers. Breguet also invented multiple striking mechanics for replicating watches, notably for your quarters, half-quarters and minutes. Just as in Breguet’s time, contemporary watchmakers face particular challenges: making the repeater as loud as possible but at precisely the exact same time making it sound pleasant. Also, repeaters can chime time at various tempos, based on how the repeater is adjusted, and a watch which chimes too quickly or too slow may seem unpleasant. Maybe more than any other complication, a second repeater requires the watchmaker to comprehend the view as a whole, since the quality of sound is intimately linked to the building of the case and dial as well.

The Supersonnerie started with the idea of taking each of the basic parts of a repeater — the system, instance, regulating system, etc — and seeing things might be done to enhance them as far as possible. APRP was set in 1986, by Dominique Renaud (who has since left the company) and Giulio Papi, as Renaud & Papi, and, through time, a few of the most well-known names in modern horology have worked there, such as Stephen Forsey of Greubel Forsey and Cartier’s head of fine watchmaking, Carole Forestier. The company eventually became a part of Audemars piguet royal oak 15300 repeater supersonnerie replica , which currently has 80 percent ownership, and APRP has been known for many years as one of the very best complications specialists on earth. A research program was set up first became evident to the general public whenever the Acoustic Research RD 1 concept watch was revealed at the SIHH in 2015 — that the watch could be observed, and the noise was notable, but Audemars Piguet gave few specifics as to the real specifics of the development process. With the debut of the Supersonnerie, however, the actions taken in that study can now be discussed in detail.
Step one was to examine the sound created by a repeater, in order to have a solid, objective basis for changes and improvements. Traditionally repeaters were tuned, and had their audio elegant, by ear. These days, however, finding a watchmaker with the crucial sense of musical tone is hard (near hopeless, Giulio Papi stated, in a discussion at APRP) and therefore, using a solid profile of the best sound characteristics was a necessary approach to start.
The solution to the problem of how to have decent tone and volume from a water-resistant watch was solved by altering how the gongs are mounted in the watch. Normally in a repeater, the cube for those gongs is screwed onto the movement plate, on the face of the movement opposite the dial (in repeaters with display backs, the only portion of this chiming system that is observable is normally the regulator, the hammers, and the gongs themselves). This means the sound has to travel throughout the caseback, which the dial, crystal, as well as act as resonating surfaces. The combination of all these factors is what determines the last sound.

When the chimes are struck, the membrane behaves like the soundboard of a string instrument like a violin or guitar. It’s been designed so that its normal frequency closely matches that of the chimes, and it dramatically amplifies the sound of the chimes in addition to providing them a clear, pleasing sound. The actual caseback covers the sparse, relatively delicate membrane and has apertures along its edge to allow sound to escape. Interestingly, the system works really well the watch actually seems louder, using a tone that is better, when the watch is secured on the wrist.
The third standard problem in repeaters is you need to have some way of controlling how fast the gongs are struck — that’s, you have to control the tempo. There are several different ways of doing this. Traditionally, watchmakers used an anchor, similar to the anchor escapement. The machine works well and it’s very reliable, but it also produces a distinct buzzing sound. Within this method, a rotor attached to the chiming gear train spins as the chimes are struck. As it turns, centrifugal force causes two arms to extend, which make contact with the walls of the rotor casing. The friction created slows the rate of chiming. The machine makes a whole lot less noise than the anchor system, however, the speed of chiming may vary over time as a result of deterioration of these oils used to lubricate the rotor. Also, the system is a lot more difficult to adjust than the anchor system. For that reason, and also because of its long use of its own legacy layouts (AP is just one of the very few businesses which didn’t stop making repeaters throughout the quartz crisis), Audemars piguet royal oak 15300st.oo.1220st.01 repeater supersonnerie fake watches has generally employed the anchor .
From the Supersonnerie, we’ve got a really modern repeater — one with audio that could easily be heard and valued even with a great deal of background sound. There are three patents granted — one for the audio board valve system, one for your method of manufacturing the gongs, and one for the miniature, nearly inaudible regulator. We were informed that the improvements made for the Supersonnerie will even find their way into future repeaters — so that, as a result of Audemars piguet royal oak diamond repeater supersonnerie clone watch Renaud & Papi, we can anticipate a whole new generation of audio.
