The function of the minute repeater is to transform the abstract concept of time into a sound message that can be directly sensed by the senses. Through the sensory translation, the time tone music tone not only becomes a meaningful message, but also presents a way to the user. Come the emotional resonance. Therefore, the minute repeater function clock is not only a demonstration of the brand’s craftsmanship, but also the most emotional craft. In recent years, the clock technology has reached its peak. In recent years, the brand has gradually shifted its focus on the development of complex functions to the minute repeater function. Using advanced technology and research on acoustics, the minute repeater function has been applied to the user’s emotional level. Into the finest movement of watchmaking.
This time we will introduce some of the current minute repeater timepieces on the market. Before that, let’s review the development history of mechanical timepieces and the influence of timepieces in the timepiece mechanism. Several key elements.
Minute Repeat Times Development History
The chronograph function is a complex function of a mechanical clock, which can emit a sound to indicate the time after startup. Different time information (usually hour, minute, minute, and possibly 5 minutes) is expressed by sounds with different tones. In the era before the popularization of artificial lighting (such as electric lights), people could only use the time-of-sound function in the dark. Recognize time.
The timekeeping function of clocks was invented by the British priest and inventor Edward Barlow in 1676. His timekeeping system composed of racks and snails became the timepiece or future timepiece. Standard mechanical structure, and British watchmaker Daniel Quare patented the timepiece in 1687 (Edward and Daniel patented the timepiece, but Daniel is earlier in terms of time).
Another key development of the chronograph is the invention of the sound device gongs. Early time clocks or timepieces were equipped with a bell fixed on the back of the case to sound. By 1783, Master Breguet had developed wire gongs, which can greatly save space. Between 1750 and 1782, there appeared a dumb repeater that struck the steel block on the case to give the time to make the watch vibrate.
The watch movement manufactured by Master Breguet, the gong device he invented can improve the space problem of the time bell design.
The development of the timekeeping system has changed from early timekeeping, timekeeping, and half quarters (half quarters) to around 1750, and the table of the current three-minute timekeeping mode (timekeeping, timekeeping, and timekeeping) has appeared. British watchmaker John Ellicott was the first watchmaker to produce such minute repeaters. After the space problem of the timepiece was improved by the Breguet system invented by Master Breguet, this three-question timepiece became more popular in the nineteenth century, but of course, the timepiece is still a very top-level clock work.
The clock’s timekeeping function gradually lost its practical significance with the advent of artificial lighting and luminus watch dials in the early nineteenth century. Coupled with the dumping of cheap timepieces made in France at this time, which severely damaged the watchmaking industry in Britain and Germany, the timepieces with timekeeping function gradually faded. Even so, because the mechanical mechanism of the timekeeping function is quite complicated, especially the timepiece with more detailed and difficult craftsmanship, today the clock or timepiece has been transformed into a pure process display, and it has become a representative of traditional watchmaking complex technology.
The development of the minute repeater function mechanism of the minute repeater is quite mature so far, and the mechanical structure will not change much. The picture shows the minute repeater mechanism on the Audemars Piguet 2907 movement.
Start with sound
Since the invention of the timepiece of the clock in the 17th century, the mechanical structure composed of racks and snail cams has been developed for many years. So Louis Brandt & amp For functional watches, the movement (manufactured by Audemars Piguet) adopts the timekeeping mechanism transplanted from the pocket watch era and is still in use today. Therefore, the brand is now focusing on the development of the minute repeater, focusing more on the presentation of the time and music.
For watch fans, the timekeeping music of the three-question watch not only symbolizes the brand’s craftsmanship, but also directly affects the emotional resonance, so it is regarded as the focus of enjoyment. The ideal timing sound must reduce the noise interference of the gear operation as much as possible, the sound quality is clear and bright, and at the same time, it further demonstrates the brand’s technological strength and personality. Therefore, the use of advanced technology to improve the core components including the hammer, the gong, and the speed control mechanism, which affect the timepiece music tone, in order to improve the quality of the timepiece music, and give the minute repeater watch a more distinctive character .
The improvement of the gong fixing method can change the effect of resonance. Vacheron Constantin’s 1731 movement extends the gong base connected to the movement to the part connected to the case, improving the resonance effect of the transmission of the time signal.
The length of the gong will affect the tone and intensity of the time. The shape of the gong also has a certain effect on the sound quality. At present, many brands have gradually changed to square-shaped gongs, thereby increasing the area of contact with the hammer to increase the intensity of the sound. The picture shows the square gong used by Cartier’s 9402MC movement.
The speed regulation mechanism is a device that determines the rhythm in the timekeeping mechanism, but the noise during operation is also the culprit that interferes with the sound quality of the timekeeping. Therefore, brands currently improve this mechanism. The picture shows the centrifugal inertial speed control device of Vacheron Constantin’s 1731 movement using aerodynamic design.
