There is no need to look at the watch in the dark. The function of a watch that knows the time just by the type and frequency of the sound of the watch is called a watch. Its vocal percussion device consists of many tiny parts, has a complicated structure, and has very strict manufacturing requirements. The first watch equipped with an chronograph movement chronograph movement was manufactured in 1892 by Audemars Piguet, and mass production of watches with a minute repeater function began around 1910. At the same time, Audemars Piguet is one of the few watch brands that has never stopped the movement of timepieces since its establishment.
At SIHH earlier this year, Audemars Piguet released its eight-minute minute repeater watch (this part joined in 2006, Audemars Piguet cooperated with the EPFL, Ecole Polytechnique Fédérale de Lausanne), Initiated a groundbreaking acoustic research program for timepieces. Today, this sound measuring device is installed in the Audemars Piguet factory, which includes a variety of professional equipment such as a muffler room and microphone recording. A team of professional technicians and experts from the Federal Institute of Technology of Lausanne jointly completed this cooperation project. The restrictions on sound transmission, including factors such as the waterproof performance of the watch, were solved, and the timekeeping performance of the watch achieved innovative progress through scientific research methods. —— Royal Oak Concept Series Super Timekeeping Watch (Model: 26577TI.OO.D002CA.01). What makes it unique is that this is not just a timepiece. Its design concept is derived from the principle of making stringed instruments. This ‘acoustic instrument’ uses a specially designed sound template to achieve extreme acoustic performance: the strings are tight Tightly fixed on the bridge. Flick the string, it will vibrate at a specific frequency, producing a beautiful sound that suppresses the frustration. The sound is emitted through the bridge on the soundboard in the main body. When sound travels in the space around the subject, its sound reinforcement effect will be further enhanced. In a space not controlled by the outside world, the bright and clear timekeeping sound is perfectly presented. In the noisy environment of SIHH, the time can still be heard clearly.
The watch case is made of lightweight titanium with architectural beauty, with a diameter of 44 mm and a thickness of 16.5 mm. The black plywood becomes the background of the steel time adjustment structure. The hollow dial presents the modern technology contained in the watch, and the precise design of the new movement is clear at a glance.
The watch is equipped with three new patents. The first is ultimate harmony. The purpose of this cooperation project is to design a stainless steel gong structure through a new method to create an exclusive sound quality. The Royal Oak concept series super timekeeping watch The newly developed case produces a unique minute repeater sound. In addition, according to the material’s cross section, length and hardness, this cooperation project also needs to set up a scientific performance evaluation system. Today, this performance evaluation system can help watchmakers determine the correct tones and tones to help watchmakers achieve unique sound effects when making gongs.
Unique structure prevents sound loss for sound reinforcement. According to the traditional manufacturing process, the gong of the minute repeater mechanism is directly fixed on the main plate of the movement. In the Royal Oak Concept Super Chronograph, the gong is mounted on a device made of a special material below the movement. The gong directly transmits the vibration generated by the hammer to the device made of special materials, instead of the traditional main plate of the movement. This technological innovation is like the case of a guitar. Through precise resonance, the sound intensity, tonality and timbre are improved.
The third is the bright tone mentioned earlier. The adjusting device for controlling the time, time and minute rhythm is also newly designed. The gong bolt is more flexible and can absorb noise generated when the time signal device is operating. As a result, the brighter and clearer timekeeping sounds created by Audemars Piguet’s watchmakers are perfectly presented.
Different from the traditional timekeeping system, if no time is required, the pause interval between timekeeping and minutes can be reduced by up to 50%. In addition, there is a specially designed protection function that can prevent the wearer from adjusting the time display to damage the movement when the alarm is activated, and can effectively improve the accuracy of the watch. In addition to the minute repeater function, the watch is also equipped with a 30-minute chronograph display and tourbillon function.
Black ceramic screw-in crown with polished titanium engraved on the top. The crown is chronograph with titanium and black ceramic buttons.
On the right side of the case are the minute repeater buttons and a titanium button protector. The watch is water resistant to 20 meters.
Black rubber strap with titanium AP folding clasp.
The movement uses a self-made Cal. 2937 manual-winding movement with a diameter of 29.9 mm and a thickness of 8.28 mm. The balance frequency is 21,600 times per hour and is assembled from 478 parts. Provides a power reserve of approximately 42 hours. The sanding, polishing and decoration of this movement is entirely done by hand to achieve the perfect quality followed by fine watchmaking.
Summary: Using a lightweight titanium case, it can sound the time without fail, and reaches the highest standards of watchmaking with unparalleled acoustic performance, sophisticated sound quality and precise tones. Audemars Piguet’s Royal Oak Concept Series Super Chronograph, which took 8 years to complete, is no different from today’s most sophisticated minute repeater.
