Innovation is the source and solid root is the root. Since the brand was founded in 1775, Baodi has adhered to the spirit of adhering to tradition and pioneering innovation. The continuous watch industry has contributed many innovative designs and endowed timepieces with richer content. The two great inventions of the tourbillon and gong reed have profoundly influenced the trend of the timepiece field. Among the many complex functions that are expected to pass through the autumn, the minute repeater function undoubtedly has a unique position. In fact, to transform the passage of time into clear notes, not only requires poetic design, but also sophisticated and complicated craftsmanship. Only the perfect combination of brilliant ideas and exquisite craftsmanship can create a true masterpiece.
The traditional minute repeater timepieces usually sounded by beeping on the bottom cover. Until 1783, the master watchmaker Abraham-Louis Breguet first used the watch wrapped around the movement. Metal wire (ie gong), to realize the function of timepiece clock. This innovative technology concept completely overturned the timekeeping structure of the traditional minute repeater, and it still has a profound impact after its advent. In 2016, Breguet launched the Tradition series of minute repeater tourbillon watches, creating a new innovative concept of the Tradition 7087 time repeater tourbillon watch. The 7087 holds 6 new patents and 5 major innovations that have never been used in a mechanical watch, making it a highly anticipated timepiece.
Carefully selected perfect sound quality
Breguet Tradition 7087 Minute Repeater Tourbillon
In order to present the perfect and pure sound quality to the world and to create an extraordinary watch, Breguet’s design engineers devoted themselves to scientific research and development, and finally broke through the problem of parts and components that present perfect sound quality. They use specially developed sound generators and have conducted more than 200,000 audio synthesis experiments in the laboratory in order to find the most beautiful sound for the human ear. After repeated listening and evaluation of these sounds, engineers selected 20 best sounds from them, and after several rounds of experiments, they were finally reduced to the 4 most suitable target sounds.
The final result is that the chords of minutes are more powerful than the hours, and the melody of a quarter of an hour sounds like a ‘ding dong’. Therefore, the melody of the two quarters of a minute sounds like ‘ding dong ding’. In order to make the tone more lively, Breguet sounds very special in the second quarter. Therefore, the half-hour tone is designed to be more special. Unlike previous models, the new Tradition 7087 sounds like ‘Ding Ding Ding’. The change of the tone of the second quarter of the clock makes it easier for the watch wearer to tell which quarter of the clock it is. Based on this choice, Breguet’s design engineers set out to develop and construct the watch. This unprecedented design concept, as well as the mastery and understanding of the various parameters of the clock, determine all aspects of the production of this timepiece, including the innovative technology adopted and the selection of watchmaking parts.
New design pursues excellence
As one of Breguet’s great inventions, the gong is the core component of the minute repeater, and the new 7087 has completely redesigned it. In the past, the gong was usually wound around the movement and struck by the hammer in the horizontal direction. This time Breguet broke the rule by fixing the gong on the bezel and struck by the hammer in the vertical direction to make the sapphire crystal. And bezel produce the best beeping effect when vibrating vertically. In addition, the hammer strikes the gong vertically in the direction from the movement to the bezel, which can promote the transmission of vibration to the radiation unit and form air vibration. The structure of the 7087 hammer is also ingenious. Because the structure of the hammer will induce the vibration of the spring, in order to prevent the hammer from rebounding and hinder the vibration of the spring, the minute repeater device usually uses a buffer spring. However, the shortcoming of the buffer spring is that it can offset part of the striking force of the hammer. To this end, Breguet’s watchmakers have invented a semi-active shock absorber that works after the hammer has finished striking, avoiding secondary strikes, thereby keeping the hammer at maximum power.
The legacy of the Tradition 7087 Minute Repeater Tourbillon watch has another distinctive feature: shaped like an ear lobe, this special design can make the sound fuller and longer. According to more than ten years of acoustic research, the gong is made of rose gold or platinum alloy with the same material as the case, and is rhodium-plated. In order to facilitate the transmission of vibration in the minute repeater, the gong is fixed on the bezel. The bezel is not firmly embedded in the case, but is fixed to the outer edge of the case with three screw posts. Because these three screw posts can vibrate freely, the bezel and sapphire crystal can resonate with the gong, effectively transmitting low-frequency sounds, and the case can also better conduct high-frequency sounds, making the overall sound quality more full. More specifically, in order to make the reading more accurate, the watch is equipped with independent cams for the hour, quarter hour and minute, which perfectly fits the 7087 movement, and the sound quality of the clock is more round and moving.
Constant mute perfect silence
Breguet Tradition 7087 Minute Repeater Tourbillon
In addition to the above-mentioned stunning innovative design, this Breguet Tradition Répétition Minutes Tourbillon minute repeater tourbillon watch uses the same magnetic regulator as the Classique La Musicale model. This patented system consists of a silver weight with a magnet around the periphery and placed around the periphery of the regulator. As the weight passes under the magnet, a current is generated opposite the magnetic field. The faster the speed, the greater the resistance, and vice versa. In this way, regardless of acceleration or deceleration, the same repulsive force will be encountered to ensure a constant speed. In addition, the magnetic regulator has another advantage: it eliminates noise. In this device developed exclusively by Breguet, the mechanical parts do not touch each other, ensuring absolute silence. In appearance, the magnetic adjuster of the 7087 is more exquisitely decorated and can be seen from the side of the dial. After repeated calculations and improvements, this innovative device finally merged perfectly with the minute repeater system. The main plate and the bridge of the movement are made of titanium metal. With proper component sizes, the noise from the time signal device can be filtered and eliminated.
Masterpiece of the highest standard
The new 7087 model has a sound cavity inside the case, called a ‘Helmholtz resonance cavity’. The sound cavity is structured to produce the resonance audio required to achieve the desired sound quality. The side of the acoustic cavity is rectangular and surrounds the entire movement, separated by only one layer of film that isolates the movement from the outside air. The sound chamber can increase the volume of the minute repeater and filter the sound of the mechanical device, and this special device can be seen through the eight holes in the lower ring around the bottom cover. More specifically, the 7087 uses a layer of gold film attached to the sapphire crystal bottom cover. Only through the bottom cover, the precise operation of the movement can be seen.
In addition to unique technical innovations, this time-honored Tradition 7087 time repeater tourbillon watch is also designed to pay tribute to Breguet’s glorious history, so it is specially equipped with a tourbillon device and a ring-shaped automatic tourbillon with automatic winding . To start the timekeeping mechanism, you usually need to pull the dedicated drive slider. In this watch, you can start by simply pressing the bayonet button. The cleverness is amazing. The handed down series looks back on the brand tradition, but also looks to the future. It cleverly blends classic and avant-garde style, has a unique aesthetic, and inherits the flawless craftsmanship of more than two centuries ago. Even the smallest parts are also hand-matted. The Tradition collection showcases the complexity that time is hard to penetrate, and deftly records the spirit of the brand. Under the leading innovative design concept, a timepiece with extremely pure sound quality and unique sound is finally created.
