The balance wheel is called the heart of the watch, and the swing of the balance wheel has a decisive influence on the running time of the watch. Around 2010, the multi-balance wheel began to be integrated into the watch design. The purpose of the multi-balance wheel at the beginning of the design is to connect two or more balance wheels through a differential, so that the error between the balance wheels can be averaged and the accuracy and reliability can be improved. The representative work of the multi-balance wheel.

Freak S is the most eye-catching work in Athens this year, and it is also the most dazzling Athens watch in my opinion so far. The biggest feature of FREAK S is that Athens designed the entire movement into an interstellar spaceship. The aventurine disc with an hour hand display turned it into a sea of ​​stars. I talked to you about aventurine, this artificial glass material, it can be said It is the most suitable material for creating a star disk. The huge carrousel mechanism rotates once an hour, the minute hand shows the bow of the combat ship, and the movement balance wheel and escapement are all integrated on the carrousel, and the second half is like the propeller of the spacecraft. Athens made a double balance wheel for the first time, using its best silicon technology to create two silicon balance wheels, parallel to the left and right, and inclined at 20 degrees. The inclination is to be more beautiful, so that the wearer can better appreciate its beating, and the silicon balance wheel has a kind of lightness and beauty due to the material and dynamic effect. Double balance wheels, connected to the differential at the rear of the “spaceship”, drive the movement through the differential, this differential can average the error of the left and right balance wheels, one with error, one without error, as long as the differential After averaging, the error shrinks. The UN-251 movement assembled in the watch also uses a silicon automatic grinding machine chain system. Through four symmetrical pawls, it captures subtle movements and converts them into energy, which is twice as efficient as the traditional winding structure. , 72 hours of full chain power. This FREAK S, with a 45mm diameter, has a case made of rose gold, black-plated titanium and ceramic.

At the Geneva Watch Fair in 2016, Audemars Piguet integrated the double balance wheel with the hollow design and launched the Royal Oak Double Balance Wheel Hollow Watch. The double balance wheel style on the picture, which uses the frosted gold process to make the case, is the most beautiful one in the series in my opinion. The ancient gold hammering process has a dazzling effect, which is reflected all the time. Very distinctive plate. The biggest feature of Audemars Piguet’s double balance wheel is that it is coaxially driven, that is, the two balance wheels can be understood as being superimposed on a shaft and driven together. Audemars Piguet once introduced that the purpose of making a coaxial double balance wheel is to improve Accuracy and reliability, but a more intuitive understanding is that its structure can be simplified, which means that the structure is simple, and the failure rate, energy loss, and environmental factors will also be smaller. The invention of this double balance wheel structure also benefits from Audemars Piguet’s previous investment in research and development, such as the innovative attempt of the double hairspring single balance wheel, the APRP director of the advanced movement research and development team introduced that they will tend to improve the movement structure by improving the movement structure. To achieve the accuracy of travel time, rather than relying solely on materials, they feel that this is not the professional field of traditional watchmakers. Hollowing is his second highlight. AP has always used hollowing out as his traditional application for high-end styles. Except for the softer hollowing out of CODE 11.59, from pocket watches to royal oak perpetual calendars to concept series, even the original millennium style, these The hollowed-out works belong to the style with a strong sense of architecture, very hard and powerful.

Finally, let us appreciate a Roger Dubuis King series four-spring balance. Roger Dubuis launched the four-spring balance wheel in 2013. After 7 years of research and development, and obtained 2 patents, he successfully developed the world’s first watch equipped with four balance wheels and five sets of differentials. . The four balance wheels are located at the four corners of the disc, and each balance wheel is also inclined at a 45-degree angle. It works in pairs, and each pair of balance wheels is connected to the differential to average out the error caused by gravity. Then average the displacement with the other pair of balance wheels. Five differentials, three adjacent to the balance wheel in the watch’s gear train, one of the three are located on the central gear, the other two are located on the third wheel, and the fourth differential is used to ensure the disc surface The crescent power reserve on the display shows the fifth next to the winding rod and two parallel barrels. Roger Dubuis RD101 hand-wound movement, consisting of 590 parts, producing a 4×4 Hz frequency. In short, this system is to greatly improve the accuracy of travel time. The brand has introduced that the four balance wheel device can offset the gravitational force that the tourbillon can offset in one minute in a very short time. This multi-layer carbon fiber style is a work launched in 2018. The carbon fiber pattern texture of the entire shell is particularly obvious in circles on the shell.

Although the design of the multi-balance wheel is to reduce the time difference of the cheap replica watches, combined with the actual development of the design in the watch field, it is the same as the tourbillon, and collectors do not care how much it can improve the accuracy of the watch. How many errors are reduced, but I simply like the cool effect brought by the multiple beating beauty of multiple balance wheels. Although the above styles are the flagship styles of various brands, the entry threshold is high, but it does not prevent us from appreciating and understanding these special top timepieces.
