Who Is More Accurate In The End: Tourbillon And Carloso

All are to reduce the effect of gravity on the time of the watch. What is the connection and difference between the tourbillon and Caruso?

 Blancpain Le Brassus Tourbillon

 At this year’s Baselworld, Blancpain’s Le Brassus series Carrousel Tourbillon watch, for the first time, integrates Carrousel and Tourbillon speed regulation systems. This is an innovative move, and it also gives people a sense of these two processes. Unprecedented attention. As two important devices designed to reduce the effect of gravity on the movement of the movement, the tourbillon and Caruso have long been famous in the watch industry, so what are their characteristics and what are the differences?


 Mr. Abraham Louis Breguet invented the tourbillon escapement at that time in order to offset the errors caused by the gravity of the tourbillon escapement system by the rotation of the tourbillon frame. At the end of the seventeenth century, people’s requirements for the accuracy of clocks increased significantly, and they could no longer tolerate such a ‘position difference’. Therefore, Baodi digs his head and seeks a solution. He thought: The reason why the escapement is affected by gravity is that its parts are in a fixed motion state. If the position of this part is constantly changed, the different orientations will cause the effect of gravity to be offset in most cases. Based on this idea, Breguet came up with a clever way. He installed the escapement speed control system in a frame. This framework is constantly spinning at a certain speed.

Tourbillon system

 Ordinary mechanical watches, because the balance spring in the escapement system will be affected by tightness and metal fatigue, and the law of balance wheel swing will also be affected by gravity, so the error is large. The tourbillon escapement speed regulation device plays a considerable role in overcoming the above-mentioned series of effects. Especially in the era of pocket watches, this type of rotary escapement has greatly improved the accuracy of clock movement. Although today’s watches are facing more position changes and the ability to adjust the accuracy of the tourbillon is weakened, the tourbillon is still a top watchmaking technology and is sought after by most watch fans who love mechanical watchmaking.

Camellia floating tourbillon

When the balance wheel is affected by the gravity in one direction at one position, it will be affected by the gravity in the other direction at another position. The frame is continuously rotated, and the position of the balance wheel is also changed accordingly. In other words, on a macro level, the influences from various directions will cancel each other out, which is equivalent to no influence.

The idea of ​​the tourbillon is to place the core escapement of the watch in a frame (Carriage), so that the frame regularly rotates 360 degrees around the axis-that is, the axis of the balance wheel. In this way, the original escapement mechanism is fixed, so when the watch rest position is changed, the escapement mechanism does not change, resulting in different forces on the escapement parts and errors; when the escapement mechanism rotates 360 degrees continuously At the time, the azimuth errors of the parts are integrated and offset each other, thereby minimizing the errors.

Blancpain’s Carrousel

The Rgulafeur Tourbillion, the ‘regular’ tourbillon, invented in 1795 and patented in 1801 by Master Baoji. Due to the difficulty of making the observatory tourbillon at the time, only a few hundred have been produced in the past two centuries. In 1892, the Frenchman Bahne Bonniksen simplified the rotary escapement and obtained a patent, and named it Carrousel-Karrusel (meaning ‘carousel’ in English, also called eccentric tourbillon). The Carloso gantry rotates much slower than the tourbillon. Depending on the design, it makes a full turn in about 34 to 52.5 minutes. Despite sacrificing accuracy, the lever-type escapement invented in the United Kingdom is simplified and structurally enhanced in Switzerland, and is better than the original tourbillon escapement. Since then, Carloso, who did not have a British lever escapement, produced it in Coventry, England, tested it at the Kew Observatory, and was partially used by the then Royal Navy.

Exploded view of movement

Although Carloso did not affect the lofty status of the observatory tourbillon at that time, or did not affect the increasingly important application of the tourbillon in the observatory. But in the twentieth century, other tourbillons other than lever-type were doomed to begin to fade away. Watches using the more reliable lever tourbillon began in 1930, and the tourbillon observatory pocket watch became the most advanced marine watch. The lever tourbillon watch has also become a frequent visitor to the observatory competition. For example, in 1945, Patek Philippe launched a lever tourbillon with a balance weight balance, and performed a dance pose at the Geneva Observatory Competition from 1943 to 1967. It was not until 1969 that the upheaval of the quartz watch entered the observatory competition came to an end.

Blancpain watch

Different from the ‘Tourbillon’ transmission structure, the lower end of the ‘Caruso’ rotating bracket protrudes from a hollow shaft, and a wheel piece is connected to the lower end surface. The sprocket meshes with the three-toothed shaft. The rotating support shaft passes through the splint and is supported by the latter. The two opposite end surfaces of the rotating support and the wheel plate serve as thrust surfaces. The four-wheel shaft passes through the hollow shaft at the lower end of the rotating bracket. The four-wheel plate meshes with the escapement gear shaft in the rotating bracket, and the four-wheel shaft meshes with the three-wheel plate outside the bracket to transfer the impulse of the three wheels to the escape wheel. The four-toothed shaft transmits the motion to the escapement toothed shaft through the four-wheel plate. The pendulum shaft is not concentric with the four-toothed shaft in the rotating bracket. Because the rotary bracket is not directly driven by the four-wheel axle, the rotational speed of the rotary bracket is always lower than that of the four-wheel axle. Therefore, the ‘Carussell’ transmission design is actually a differential planetary gear train.

Comparison of tourbillon and caruso

Caruso is another innovation in clock technology after the tourbillon. Many netizens are not very clear about the difference between these two technologies. In simple terms, they have the following differences:

1.The tourbillon generally rotates faster than Carrousel;

2.The tourbillon has more parts than Carrousel;

3. The tourbillon is generally driven by four wheels, while Caruso is five wheels;

4. Carrousel is mostly eccentric design and does not rotate around fixed gears.

9102 Years, Rolex’s Myth Should Be Broken (二)

Little Elephant Pigeon has written a professional article for everyone, and has picked up two stars. This kind of lazy behavior means deep guilt. So today, finally, I am more literate (beating people but not humiliating). In the last issue, after hammering the three myths of Rolex hard, one fan commented that Rolex, as a watch brand with excellent quality, has always maintained innovation and Your original intention: Quality comes first. There is no denying that the Rolex is good, but blowing it too much is not advisable. The group is still very annoying on the bezel. Rolex has no history of black water ghosts today will be a few other Rolex myths blown into the sky, continue hammering! Myth 4: 904L steel is known to be supreme. The steel used in watches is the most commonly used 316L steel, while Rolex uses 904L steel. So what is 316L steel and what is 904L steel? Why use 316L instead of Rolex? 904L and 316L are both American names for steel models, which are the standard steel numbers of the ‘American Society for Testing and Material (ASTM)’. 904L, 316L material comparison According to the composition comparison chart, we can see that the amount of each metal element in these two types of steel is basically the same. However, the alloy content of 904L steel: nickel, chromium, molybdenum is 1.6 times higher than 316L steel, and 904L steel has more copper elements. Rockwell strength (HRB) of both steels is ≤95, so there is almost no difference in strength and hardness between the two steels. But because of the higher alloy content of 904L steel and the addition of a small amount of copper, 904L steel is much stronger in corrosion resistance and wear resistance than 316L. At the same time, it also causes the weight to be heavier than 316L and has a heavier feel under the same volume (fitting with the Rolex temperament). 904L steel 316 steel also has a name called medical steel, which is widely used in the food and medical industries. 316 steel is not easy to allergic to metal allergies. 904L refers to an ultra-low carbon super austenitic stainless steel, which is commonly used in high-tech, aerospace and chemical industries, and is also the main application material for petrochemical equipment reactors, sulfuric acid storage, seawater processors and other applications. 904L steel In general, 316L steel completely meets our daily needs, no one will throw the watch into sulfuric acid, right? Even when it comes to seawater, it is corrosive, and 316L steel is enough. And 316 is less sensitising. And 904L, as industrial steel, is just a little more resistant to corrosion. For the average consumer, there is little real value. Rolex deserves to be the master of marketing in the watch industry (the set of water ghosts and Lukindi is a model). I personally think that the main purpose of 904L steel is for marketing. As the mainstay of the Swiss watchmaking industry, Rolex has always sought to be different. Functionally, it’s on the shell. Myth 5: All In-house Rolex watches are all In-house (self-produced)? Sorry, absolutely impossible. Rolex official propaganda is ‘from the casting of gold alloys to the processing, grinding, assembly and decoration of movements, cases, dials and straps, all important parts of Rolex watches are fully designed and developed by Rolex.’ Rolex 3255 since Make a movement and play a word game. He said all the important parts, so what’s not important? The Swiss watch industry has always had a very clear division of labor. Until eta was monopolized, Switzerland had maintained a stable production line. The division of labor is clear for gem-making, glass, case, movement parts, and assembly. Although the status quo has changed, Rolex has also acquired its own movement factory (Aegler). However, artificial Jewels and sapphire crystals from Rolex movements are produced by professional Swiss manufacturers. In order to avoid being sprayed, blue niobium hairsprings, plus, Rolex is also the only Swiss watch brand that can mass-produce alloy hairsprings in addition to the Nivarox plant. Myth 6: Only the self-produced movement is going to die! Not only have used other people’s movements, but also provided movements for others! Baidu search results are directly from Baidu Rolex’s self-produced movements, which are basically the results. How many people have been deceived by this result, gosh. Around 1986, Rolex did not have its own stable chronograph movement, and did not want to use the eta7750. In the same period, Zenith already has its own El Primero and is extremely popular, stable and high-end. Zenith El Primero, so Rolex purchased Zenith and installed the movement on its own Daytona model. Replace half of the parts and reduce the frequency to 28800. It became the Rolex 4030 movement (it is a modified version of Zenith). Rolex 4030 movement Until around 2000, Rolex really had its own chronograph movement 4130. Rolex 4130 movement strictly speaking, 4030 does not belong to Rolex’s own movement, 4130 is. The Rolex 5055 quartz movement is also the Rolex quartz watch that we mentioned in the last issue of Rolex. Before Rolex 5055 movement. Omega launched the Beta22 movement, which produced up to 12,000 pieces. At that time, Rolex purchased 650 of them from Omega, so Rolex also used Omega movements. Omega BETA22 quartz movement Rolex and Omega have such a past, it is also rare. . . This is the end of this series of Rolex myths. Once again, Rolex’s strength is indeed eye-catching. Later, it will also explain Rolex’s innovative actions. Blow high and fall badly, don’t try to kill a brand. I hope that the fat friends who have finished watching have a deeper understanding of Rolex. Disclaimer: This article is an original work of the author and represents the author’s opinion only.
