Based on the original model and the traditional watchmaking technology from 1791, Girard-Perregaux watches are constantly innovating, showing the outstanding contribution of innovation to the continuous development of the watchmaking industry. For example, this three-gold bridge tourbillon The minute repeat watch creates the mechanical structure of the timekeeping device from a new perspective, highlighting Girard-Perregaux’s long-term determination to continuously break through technological innovation, while respecting the aesthetic tradition and the time-honored exquisite watchmaking technology.
Girard Perregaux Triple Golden Bridge Tourbillon Minute Repeater Watch not only represents an efficient and beautiful timekeeping device, but also brings pleasant visual enjoyment to everyone
The mechanical structure of this Sanjinqiao Tourbillon Minute Repeater watch is unique. For the first time, it has provided the world with simultaneous observation of the components of the time-keeping device and the hammer with the sound of the percussion spring. Optimizing the sound transmission of a watch is a major innovation in the watchmaking industry. Girard-Perregaux has set ambitious goals, and is determined to invite watchmakers and engineers to work together to create new movements, pure mechanical structures, and let people see the usually hidden parts. This craftsmanship concept stems from the belief that the company’s watchmaking skills and traditions will be carried forward and become a permanent classic. In order to meet this concept, this minute repeater watch specially selected the Sanjinqiao Tourbillon device. The three-gold bridge tourbillon is the symbol of GP Girard-Perregaux. Its design was patented in 1884 and is still regarded as the highest example of the aesthetics, craftsmanship and essence of the Swiss watchmaking industry.
Based on tradition, be brave in innovation
For watches with minute repeaters, the loud, crisp sound seems to be a big resistance for many watch manufacturers. In order to significantly improve the timekeeping sound of timepieces, dozens or even hundreds of solutions have been proposed. Among them, the principle of timekeeping first appeared in the early 17th century. However, GP Girard-Perregaux has no intention of adopting previous solutions, because these solutions have not succeeded in producing crisp and pleasant music, pleasing the ears, and giving the wearer the opportunity to see the components of the constantly running timekeeping device. In order to open up a new world in the traditionally restricted watchmaking device, GP Girard-Perregaux proposes to use the classic models as the basis for most of the components of the Sanjinqiao Tourbillon device and the three-pointer device to make a crisp and pleasant sound. On the front, even if worn on the wrist, it can still make a clear and clear sound, which is exciting. To achieve this effect, our watchmakers not only redesigned the entire movement, but also changed the original structure and working principle.

Create pleasant sound
The complexity of the creative design currently in use is not inferior to the original, fully revealing the exquisite structure of the three-question device, which makes the wearer full of eyes and delight both ears. It is worth mentioning that the timekeeping system here is cleverly set and operates by sliding the bolt at 8 o’clock on the left side of the dial. Slide this trigger to re-upload the gong in the barrel (the mandrel is partially visible at the bottom case). Once the maximum limit is reached, the three-minute clockwork releases the ‘connect-disconnect’ control, which is specifically designed to prevent the timing device from starting before the clockwork is finished, thereby preventing the incorrect tone from being emitted at the time. The improved timekeeping device exposes the components and can be seen at a glance through the dial opening. At the same time, the hammers and gongs are cleverly arranged on the dial to be on the same side as the timekeeping device, which is not only convenient to observe the operation of the trigger device, but also You can also enjoy the hammer hitting the gong. It can be seen that among all the elements of the three-question device, there is only one element—the complex flywheel cannot be heard and visually sensed. The flywheel is dedicated to adjusting the striking speed of the hammer and is located at the bottom shell, which can limit sound transmission, although Seemingly insignificant, it is enough to guarantee the sound quality of this watchmaking instrument.
The improved striking device still retains the original traditional decoration. These delicate components first wind the clockwork, then release the hammer, and finally strike the gong in an orderly manner, first reporting the hours (bass), secondly the quarter clock (high and bass mixing), and finally the minute hand (treble). , Rich tone changes. The design of the two gongs facing the inside of the 18k gold time ring and the clever layout of the hammer (the shape of which is inspired by the patented Golden Bridge in 1884) are free of conventional aesthetic standards. This layout facilitates regular adjustment at a carefully calibrated frequency , Send out harmonious sound waves, get rid of the density of sound waves that are easily absorbed due to being too close to the skin, which affects the sound quality.

In addition, the watchmaker has carefully studied the relationship between the case size and the movement to provide the best possible spatial arrangement, such as the string device. Even more surprising is that the inside of the case has been specially processed and modified to limit any sound quality interference that can occur. Moreover, because erroneous notes are not allowed, the sapphire glass bottom case has been specially processed to give it beautiful radians unique to most acoustic instruments, and to maximize the range of sound reverberation.
Half instrument, half power sculpture
This is a very unusual timekeeping device. At the same time, it uses multiple excellent technical solutions to achieve the extraordinary performance of the Sanjinqiao Tourbillon Minute Repeater. Therefore, in order to improve the transmission of sound waves between the two gong ends, the connection between the splint and the 18K rose gold case has been strengthened. However, this is not enough. In order to increase the speed of the hammer and the striking effect, the hammer is set in a pair of jewelry, acting as a ball to reduce friction. The design of this structure has a seemingly simple and harmonious visual effect.

Seemingly simple things, but actually have extremely complex and demanding requirements. It takes at least 270 hours for a professional watchmaker to assemble and adjust this extraordinary device. The production process of the three-question device is extremely complicated. At the same time, the hammer is placed on the same plane as a bracket, and the mainspring is tightened before hitting. It is necessary to use a special tool to simulate the future position outside the movement to adjust the hammer. This makes the job more time-consuming and labor-intensive. Nevertheless, the final results are obvious to all. These small components made of black polished stainless steel have been beveled to highlight the original design inspired by Sanjinqiao. It has high inertia and can produce clear, pleasing notes with each hit.
Mechanical structure guided by Girard Perregaux’s traditional craftsmanship
To carry this extraordinary device, Girard Perregaux chooses a round case with a dome-shaped strap and slender lugs on both sides, which is a classic representative of the fine watchmaking industry. The soft beveled groove provides a wide opening for the movement, which helps to better appreciate the grand layout of the minute repeater, hammer, gong and tourbillon. The iconic GP Girard Perregaux arrow-shaped golden bridge elements and splints continue the brand’s classic tradition while unmatched decoration, defending its orthodoxy. The movement is exposed at the bottom case, with three golden bridges and a splint engraved with the Girard-Perregaux logo on the front.
