Roger Dubuis Excalibur Quatuor Four Balance Watch Most Shocking

Roger Dubuy has always been a brand that is good at blending its own characteristics with professional technology, thus enjoying a high reputation in the field of mechanical watches. The Excalibur series, which was born in 2005, will soon launch several new works in 2013, which will become the focus of much attention at the Geneva International Horological Fair. The Excalibur Quatuor four balance watch is the highlight of this year’s Roger Dubuis at the SIHH watch exhibition, known as the ‘most shocking’ model.
Roger Dubuis Excalibur Quatuor Four-Wheel Watch-Rose Gold
 At first glance, the Excalibur Quatuor four-wheel balance watch gives a strong shocking feeling. There are four balance wheels around the four corners. There are two balance wheels on a watch. F.P. Journe once put two balance wheels on Chronometre a Resonance, so that they absorb each other’s energy, coordinate the frequency between each other, and make the watch more accurate. Even Roger Dubuis also launched the Double Tourbillon with two sets of balance wheels, but this time a total of 4 balance wheels appeared, but a groundbreaking initiative in the history of watch development.

 Due to the gravitational force, as the wrist swings, the position of the watch changes continuously, resulting in running errors. Although the tourbillon can solve some problems, Excalibur Quatuor offers a new solution. Excalibur Quatuor’s four balance springs work in pairs and are carefully laid out to instantly offset running errors caused by position changes. In other words, the tourbillon cancels the gravitational force in one minute, and the Excalibur Quatuor can instantly cancel it. The layout of the four balance wheels is that the upper two balance wheels are combined into one group, and the lower two are another group. Each group is connected by a differential, and then the third differential in the center is used. By connecting the upper and lower two groups, the average power can make the watch go more accurately under the two pinch attacks.
16Hz high-speed swing frequency effect

 Using 4 balance springs, according to the brand, has another benefit, which is to achieve the effect of high-speed swing frequency. Watches typically swing at 28,800 times per hour, or 4Hz, which is considered highly accurate. Currently, four 4Hz balance wheels are used. Because they do not necessarily start at the same time, one starts to swing and the other swings immediately. Swinging 8 times in one second can be combined into 32 times in one second. Together with making finer gears, 4 balance wheels have the opportunity to achieve a 16Hz highly accurate effect of dividing one second into 32 divisions.
5 differentials
 Since there are four balance wheels, it is conceivable that the number of parts of the movement will not be too small. The manual-winding movement RD0101 consists of a total of 590 parts. There are 113 gems alone, and there are even 5 differentials. In addition to the three in the gear train transmission wheel system, there are two other, one to control power transmission, and the other to connect the winding handle and two barrels. The entire movement took 7 years to develop. In addition to the brand-new mechanical design of the Quatuor, the brand has not neglected in appearance. The watch has a fully transparent design on both the surface and the bottom of the watch. You can enjoy the masterpiece made with 7 years of hard work. In the semi-hollowed movement, the four balance wheels are the protagonists. They have a beautiful posture. Unlike ordinary balance wheels, they lie on their sides gently, giving people the feeling of being ready to fly.
Power reserve display at 9 o’clock
 Aside from the protagonist, the power reserve display at the 9:00 position is also a novel design. It is not just a one-degree arc like a normal watch, but a circle formed by two arcs one on top of the other, similar to the Chinese Tai Chi symbol. The two small pointers for instructions are far away. Whether you like to read the upper half or the lower half, it is a new reading experience.
