All-around champion -ETA 2824
ETA 2824 self-winding movement appeared in 1982 is very common in the market. It also has the 2824-2 version, with a size of 25.6mm X 4.6mm, 25 stones, a vibration frequency of 4 Hz, and 38-hour dynamic storage, and is known as the "all-round champion". Because of the stable quality, there are different materials and grades to choose from, and many brands are using them.
For example, Hollysys large crown pointer calendar watch is equipped with Oris Calibre 754 movement, which is an improved self-winding movement based on Sellita SW 200- 1 (structure similar to 2824-2).
For example, Tudor Qicheng series Biwan 4 1 is equipped with ETA 2824 self-winding movement.
Another example is the 60th anniversary replica of Longines Concas, which is equipped with the Caliber L633 self-winding movement based on ETA 2824/2.
King of watches Eta Valjoux 7750
ETA Valjoux 7750, 30mm X 7.9mm, 25 stones, 4 Hz vibration frequency, self-winding. In addition to the advantages of stable quality and simple structure, it also reduces the cost because of the use of cam structure, and has become the favorite of chronographs in large and small brands. Brands that use it include IWC, Breitling and Habring, a top independent watchmaker? Wait a minute.
Achievements of the Advanced Watch ETA 2892
The best choice for advanced watches is ETA 2892 self-winding movement, with the size of 25.60mm X 3.6mm, 2 1 stone and the vibration frequency of 4 Hz. Because different functional modules can be added in its ultra-thin design, the movements originated from 2892 include TAG Heuer Caliber 12 chronograph movement, 2893 dual time zone, 2895 small needle and so on.
In the early years, the Omega Semaster was 200 meters, with a 2892 movement inside.
Mido Belem Seri commemorative ultra-thin watch is equipped with Mido 1 192 self-winding movement, based on ETA 2892-A2.
Complete the complex model -ETA 775 1
The movement of the complex watch ETA 775 1 includes timing (30 minutes, 12 hours), month, week, day and night indication, and moon phase function. Its appearance has affected the price trend of multi-functional complex watches, leading many brands that have not developed complex movements to launch their own complex watches early.
Tractors in the era of big watches -eta Valg series
After 2000, large watches became more and more popular, and the new ETA Valgranges series came into being. The following are Valrange A07. 16 1 used by Junker in Germany, Valrange A07.23 1940 used by Longines, and Valrange A07.640 used by Junker in Germany.
Times are changing, people's aesthetics are changing, but the position of ETA movement in the watch industry remains unchanged, which deserves the respect of every reader.
As long as you know a little about watches, you must have heard of this movement. So what is the ETA movement? As a frequent watch player, how much do you know about ETA? Let's talk about it today
ETA is a factory owned by Swatch Group, which specializes in the production of movement. Eta is a giant in Swatch watch industry and the largest watch manufacturer in the world so far. ETA, owned by Swatch, is the largest manufacturer and supplier of blank movement in the world, and it is also the movement with the highest utilization rate so far. Eta is well known.
Perhaps when it comes to ETA, many people will scoff and think ETA is just so-so. But the interesting thing is that the mechanical watch you are wearing is ETA movement. You should know that many brands' so-called "homemade movements" are improved by ETA, and it is difficult for you who like watches to bypass this movement factory.
So which is better or worse, homemade exercise or ETA? Actually, there is no comparability. For eta, it can be said that it is a very good and cheap movement, and its performance is definitely better than ETA. Starting from 20 13, swatch reduced the external supply of ETA movements, which also "forced" many brands to start developing their own movements.
Let's take a look at three ace moves of ETA.
ETA2892A2
This movement can be said to be quite excellent. It was once used to compete with Rolex Cal.3 135 for the title of the strongest self-winding movement. This movement is mainly used for relatively advanced watches.
The 2892A2 movement has a diameter of 25.6 mm and a height of 3.6 mm, and is set with 2 1 ruby. Motherboard, base plate, splint and pressure plate are all made of traditional brass. It is equipped with a ring-shaped balance wheel, which is self-winding in both directions, vibrates 28,800 times per hour, and has an "eccentric screw trimmer" to facilitate precise fine adjustment.
ETA2824-2
This is a very stable movement, mainly used in the low-end market, slightly thicker than the 2892 2824 movement. We can find ETA2824 in many brands, such as Tissot, Dumet, Tudor, Breitling, Aimei and so on.
ETA7750
This movement is very powerful and is called "high plasticity" movement. It can not only be used as a chronograph, but also be converted into a perpetual calendar, chasing needles and so on. The stability of the action is very good.
The standard 7750 is equipped with 17 rubies, which can be stored for 42 hours and vibrate 28800 times per hour. One-way winding design is adopted, the pointer fine-tuning device with the same principle as eccentric screw is used, and there is scale indication, which is convenient for fine-tuning operation.
ETA is one of the most powerful companies in the modern watch industry and the largest movement manufacturer in Switzerland. Now there are countless minority brands and major brands in the market using their movements. But for many people, this ETA company is still a relatively unknown company.
One of the reasons is that many retail brands will take pains to promote their products to buyers, but unlike ETA, they will not sell them directly to the public, so they will never publicly publicize their technological achievements.
Another reason is that the movement has now become the main selling point of most high-end watch brands. Therefore, for watch brands without their own proprietary movements, the general method is to rename ETA (or movements provided by other movement companies) to the name chosen by the brand. Even some movements, such as ETA/Sellita/Soprod, are modified according to the company that bought it.
In doing so, ETA seems to be an unpopular company name for people who are relatively unfamiliar with the watch manufacturing industry. But in fact, without ETA, the Swiss watchmaking industry would never be what it is today. Eta made great contributions to the watchmaking industry during the two world wars and the timely revolution. Today, the movement produced by ETA still occupies half of the watch industry.
Usually ETA caliber has four different "grades", which correspond to different finished product quality, sports quality and different prices. The standard level is cheap and of good quality, with an accuracy of +/- 12 seconds per day and a maximum position change of 30 seconds. Elaboré is a progressive class, and her performance in the standard level field has improved by 7 seconds and 20 seconds. Compared with the last two grades, the top grade is the top grade, with the best finish and higher parts quality, with the accuracy of 4 seconds and 10 second. Finally, the observatory level, which is the top movement certified by COSC.
For unfamiliar people, the most common ETA movements are manual winding 6497, automatic 2824-2, automatic chronograph 2894-2 (chronograph template produced since1996) and 7750 (automatic chronograph and watch chronograph produced since1973).
This clearly shows that ETA has many choices, and brands can choose according to their own needs, prices, conditions of use and quality. Although ETA is the boss of the sports company, according to the current situation, it is also facing some crises.
One is about the legal defendant of monopoly. In fact, there is little choice but ETA. If ETA stops supplying parts and movements to other companies, the affected companies will go out of business because they can't find substitutes. If they decide not to sell to outside companies, they will face the risk of being fined for antitrust crimes.
The other is that many actions of ETA were designed many years ago. Depending on the type of patent, the patent is valid for about 20 years, so nothing can stop competitors from cloning, just like Sellita did when designing several most popular movements.
The picture above shows the comparison between Sellita and ETA. You can compare the official charts of Sellita SW300 (left) and ETA 2892 (right) to see how similar they are. Therefore, ETA has reduced its brand sales now, and most of its energy will be devoted to the new movement developers who will supply it in the future.
ETA has merged Swiss manufacturers of all sizes from the historical trend. This unique past has enabled the company to acquire the valuable skills and experience of these participants and turn them into a team that is ultimately responsible for saving and revitalizing the Swiss watch industry. Although it played several key roles in the 20th century, in the next few years, it will certainly open up more space for other companies and eventually create a world of watch movements with more functions.

In fact, the performance of the movement is closely related to the importance of watchmaking materials.
Sports performance and accuracy
I have to say that the biggest disadvantage of mechanical watch core compared with electronic watch core is that it is not so accurate and reliable. We all love analog display, which can be observed and understood by naked eyes, and attracts most watch lovers. Although the accuracy of mechanical watches will not reach the level of most quartz watches, I very much hope that the manufacturers of mechanical watch movements will make persistent efforts. Because those mechanical watches that pay attention to the overall performance, especially the accuracy, are very attractive to me.
In my opinion, the most important value of a watch lies in its main function-accurate timing. Personality factors determine that I don't want to accept things that don't have practical functions, so I prefer beautiful tools and ignore those that don't have utility. In this way, those watches that have made a breakthrough in accuracy win my heart the most.
In fact, the performance of the movement is rarely mentioned in the watch industry. There are far more reports about new artistic designs and decorative materials than better movements. Even so, there are always several brand-new concepts and mechanisms in a year to promote the evolution of mechanical watch cores in a more precise direction.
These new technologies range from materials (such as silicon-metal composite structures used in specific applications) to overall system design (such as the redesign of balance wheels). And new materials and new designs are often combined. A minefield for watch collectors is to distinguish useful innovations from useless ones. In other words, not all sports innovations will make sports better. Consumers need to do their own research and carefully screen the manufacturer's promotional copy to determine whether the new sports system is really useful or just a gimmick. Watch manufacturers often ignore the details of the actual working principle of the movement, such as working frequency, speed and energy storage times.
When it comes to accuracy or isochronism, manufacturers are silent. A completely understandable reason is that two identical actions may have different performances under different deployment methods and user usage methods. The more direct reason is that because most users of mechanical watches do not use it as the main time-telling tool (most people choose to use mobile phones), manufacturers have no incentive to greatly improve their performance. It seems that the pursuit of mechanical watch performance is not enough to impress most collectors, but it is even more difficult to achieve this goal in practice.
durable material
The patina on an antique watch may be cool, but I don't want to see my watch age with me. So I have been looking for watches made of durable materials, which can resist scratches, dents, wear, fading or other damage. Clocks and watches are real investments, unless you are interested in investing in objects that will age over time (such as bronze watchcases). I think most people like me want their investments to look as long as possible. There is nothing worse than the first small scratch on the metal shell.
The popularity of ceramic case material is mainly attributed to its wear resistance. Although ceramics will break under heavy blows, most people tend to think that its high wear resistance is enough to make up for it. In addition, the polishing and color of ceramics are not easy to age. Many colored materials will change color or fade when worn for a long time, which is a lesson of many antique watches. Ceramic materials have rare color stability. Now the pure white ceramic case will remain pure white and polished for a long time.
Expected materials and design
Aesthetically, I am very interested in the design influenced by modern machines. People's favorite retro sports watches are inspired by the design of contemporary ships, planes and cars. When designers reproduce the aesthetics of retro watches in contemporary watches, the results may be positive or outdated. Personally, this problem stems from the fact that many watch manufacturers have not explored the connection between watches and what people see every day.
I have said so much, hoping to encourage collectors to boldly invest in novel designs that seem different. It takes courage and confidence to buy something strange at first sight. However, if it doesn't suit your taste at all, there is no need to be angry about why it exists. Not all objects should or can attract everyone.
Both ETA 2824 and ETA 7750 have good stability. 7750 automatic trailer is a bit loud, with good error and stability. Leather is strong and durable!
I was lucky enough to visit the Swiss ETA movement manufacturing company under the Swatch Group (the factory is located in Glenxing, a small town in the northwest of Switzerland, and photos are not allowed in the factory). ETA is the world's largest manufacturer of universal movement. At present, 85% watches made in Switzerland in the world will use ETA movement. Among the remaining 15%, there are top brands in the industry-homemade movement brands, and there are also a few tiny brands that can't afford ETA movements.
Before1965-1the "timely revolution" broke out in the mid-1970s, no Swiss super-large movement manufacturing company had such a high concentration as ETA. The manufacture of the movement is basically a private matter of each brand. However, the great environmental changes brought about by the "timely revolution" have completely changed the Swiss watchmaking industry. The establishment of Swatch Group and its ETA movement company are two notable signs.
ETA has gathered at least Valjoux (chronograph movement), Unitas (pocket watch movement), Peseux (ultra-thin manual movement) and other well-known movement manufacturers in Switzerland. ETA has also developed ETA2892 automatic movement, which is regarded as the "core of god" by the global watchmaking reputation.
Eta movement is synonymous with stability, reliability and universality, much like a blank room. From a few hundred yuan Swatch watches to many top brands with hundreds of thousands and millions, ETA movements will be used (or complex functions will be superimposed on ETA movements). Different brands have great differences in polishing, modifying and upgrading the rough ETA movement, so the price of the whole watch is also very different.
As a watch fan, ETA is one of the terms that must be familiar, because it is the largest movement manufacturer in Switzerland. From electronic watches that cost only a few hundred yuan to jewelry watches that cost tens of millions or even millions of yuan, ETA movements may be used.
In history, there used to be many professional companies famous for manufacturing movement in Switzerland. However, the timely crisis in the 1970s caused the Swiss watchmaking industry to go bankrupt, and a series of professional factories gradually merged into a part of ETA, a subsidiary of Swatch Group, including a professional company specializing in manufacturing hairsprings or shock-proof mechanisms, Valjoux, which is famous for manufacturing chronograph movements, and Peseux, which is famous for manufacturing ultra-thin movements. Unitas, which is famous for manufacturing large-size pocket watch movements, has become the leading professional movement manufacturer in the industry, and its users are far from Swatch Group, but the global watchmaking industry including China.
Among the movements produced by ETA, the most famous ones are 7750 chronograph movement, 2824 and 2892 self-winding movement and 6497 large-size movement. These movements have been modified or decorated by different manufacturers and become the core of high-end products with different styles. As simple as an ordinary three-pointer watch, as complex as a chronograph or a perpetual calendar, it may be made by relying on the basic movement provided by ETA. It can be said that without ETA, more than half of the people in the whole high-end watch market may lose their dependence.
I'm Zou Sanshan, a senior watch lover and a self-media watch player. I am committed to providing you with an attitude, depth and temperature watch service. For more watch knowledge, please search the e-book "Zou Sanshan's Tips for Playing Watches". Eta movement is one of the largest manufacturers of watch movements in the world, belonging to Swatch Group. Not only its Tissot, Radar, Longines and other brands are used, but also many watch brands are in use. The blank movement provided by ETA is also the basic version of many brands' improved movements. As long as you buy a Swiss watch, it is difficult to bypass this movement factory. The ETA movement is divided into four grades and the workmanship is divided into two grades. The four grades of ETA movement are 1, standard) 2 and Elabore. The workmanship of these two grades is similar. The gemstone used for bearings is a polymeric gemstone, which is polymerized from powder, and the shock absorber is also very basic. 3. Top-class, that is, movements above 2824, such as ETA2892 movement with three-stage polishing. Many of these styles are K gold pendants. 4, Swiss Observatory level, the main difference lies in the strict detection error.
This is a classic movement, and many mechanical watches are in use. In fact, many famous brands and low brands are using ETA movement. Perhaps the same movement may be used on different brands of watches, but the prices are far apart. One is the brand premium, and the other is the polishing degree of the movement. The mechanical watches of Tissot and Longines are the same as many movements, but the polishing degree is different, and the travel accuracy is different, not only the price is different, but also the actual experience is better. Therefore, the movements of those observatory's standard mechanical watches are well polished, and all kinds of waterproof and shockproof travel time accuracy is better and the price is higher, which reflects the painstaking and superb skills of watchmakers.
