Omega OMEGA anti-counterfeiting, brand model and movement knowledge Omega OMEGA anti-counterfeiting knowledge (1) Look at the production serial number of the watch case. Almost all Omega watches have a production serial number, and it is one number for each watch, and it is also unique. . It is usually engraved on the back cover of the watch, or on the back of a claw of the watch. It is an 8-digit number. If it is a mechanical watch, the 8-digit production serial number will also appear on the edge of the movement splint. The production serial number of the case is consistent with that of the movement. The production serial number of a real watch is engraved, very deep and clear. If it is engraved on the back cover of the watch, it will be consistent with the arc on the back cover of the watch. That is to say, the numbers will also be arranged in an arc shape, and Fake watches are generally arranged horizontally. The production serial number of the current Omega watches is engraved on the back of a certain claw position, and the numbers are engraved very small and densely. This practice cannot be imitated by fake watches at present. The production serial number of fake watches is basically the same number, regardless of whether it is a men's watch or a women's watch, or what model it is. Once I found 3 fake Omegas, and the production serial numbers were actually the same (80456374, see picture ). (2) Look at the logo on the watch case, especially the K gold watch. There are many logos on the watch case, such as the scale pattern, the 18K or 750 mark, the dog head of Saint Bernard or the woman head mark of the "Goddess of Protection of the Country". These marks are stamped very small and clear, while fake watches are often thick and blurry. (3) Look at the logo on the strap. If it is a metal strap, there will also be some logos engraved on the discount of the strap. There must also be a strap number. The logos on fake watches are generally larger, shallower and lighter. Rough, this place is not easy to do in terms of craftsmanship, and fake watches are often exposed here. If it is a K gold watch, the buckle of the strap must also be K gold and must be engraved with K gold logos. If not, it is gold plated. Recently, I found that some Omega watches with belts have problems in this area. That means at least it's not the original strap. (4) Look at the hands of the watch. The weak point of counterfeit watches is the hands. Even though they are small, it is not easy to make them look alike. The surface of the hands of the real Omega watch is very bright and smooth, with regular and slender shapes (especially the second hand). The luminescence on the hands is consistent with the color on the dial. If you can make a comparison, it is not difficult to find the difference between them. (5) The characters on the dial and the characters on the lacquered dial should also be very regular and bright. If it is a diamond character, first of all it should be a natural diamond, while fake watches generally use "rhinestones" and are made better than real watches. It's big. The lacquer prints on the dial, including the letters and lanes, should be very clear and shiny. Fake watches should be darker and blurry. The words SWISSMADE should be at the bottom at 6 o'clock on the dial, close to the aperture of the glass. On fake watches, the letters are printed higher up. (See photo) (6) Look at the guarantee card of the watch. Omega watches usually have 2 to 4 guarantee cards (depending on the model of the watch). They are all dark red and the same size as a credit card. The number of the watch (watch model, production serial number, movement number and blue stamp of the seller) is printed on it, which corresponds to the watch one-to-one. Contents of the guarantee card: including international guarantee, chronometer certificate, natural diamond guarantee and watch function guarantee.

Fake watches often have mismatched numbers, mismatched functions, and lack of seller blue stamps.

Therefore, when I chose to introduce, I paid attention to the following aspects: OMEGA has not always been a brand known for its high difficulty.

Although it has a tourbillon and a perpetual calendar, they are just symbols of strength and class and are not truly mass-produced. The movement I choose must be available in large quantities and must be common in the market. It needs to be of high quality and immature products that are often broken and often repaired. I won't choose it. It must be an epoch-making product made by OMEGA itself, and I won’t choose it if it is sold by buying a core. It must be a mechanical core. Although OMEGA has several representative electronic quartz products such as 1300, 1611, and 1330, I would not choose it. Okay, let’s take a look at the five watch movements that I selected to represent the history of OMEGA: The Five Generals of Ouji Movement. 1. The Mang Kunlun 19 Order was born. Time of production: 1894. Designer: Franois Chevillat. Diameter: 43mm, 17 diamonds. Swing width: 18,000/hour. The 19 Order is an epoch-making product. Its greatest significance is that it laid the foundation for OMEGA and even the Swiss watchmaking industry to mechanize the production of precision parts and form the concept of subassembly and assembly. Switzerland's watchmaking industry continues that of France. As early as 1601, Switzerland created the Geneva Watchmaking Association. Although there were more than 500 watch factories at that time, they all used manual watchmaking, and the parts of each watch were unique. Fits a watch. Unable to mass produce. In the 19th century, factories in Switzerland and the United States mechanized the mass production of watches. The American Waltham Watch Company is one of the representatives. They became pioneers in the use of advanced and sophisticated mechanical watchmaking technology. At this time, the Louis family in Switzerland moved their factories and equipment to the Biel area, which has sufficient manpower, rich resources and convenient transportation. They abandoned the old assembly system and began to design more sophisticated and advanced machinery and technology. They used experienced designers and workers, adopted mechanized production methods to produce parts with uniform specifications, and introduced a new division of labor system for assembly work. In 1894, the achievements of the Louis family came to fruition, and the famous epoch-making movement ---- 19-ring came out. All parts are produced on an assembly line, and the parts are interchangeable. This reduces a lot of manpower and fully improves product quality. And it was also in this year that they gave the product an unprecedented name: OMEGA. This 19-mm movement had the most advanced structure at the time, a horse-style escapement, and was equipped with a bimetal truncated counterweight balance wheel and a wound blue steel hairspring. The fine-tuning on the balance plywood also used an ultra-precision scroll speed. Fine adjustment device. The beautiful polishing and the jeweled bearings with gong wire locking make this early industrialized production product beautiful and beautiful. As soon as the 19th Order came out, it began to break countless observatory competition records. In the 1936 KEW competition, he even scored 97.8 points, which remains the highest score record to this day. You must know that the most accurate movement of all mechanical watches in the world is this movement. 2. The 30MM that can swallow thousands of miles like a tiger: Production Year: 1939-1963 Production Quantity: More than 3 million Designer: HenriKneuss Index : Diameter 30MM, thickness 4.05mm/5. 1MM 15/17 diamond swing 18000A/h power reserve 42h As a watch movement, it is worthy of special mention. Its origin is said to be due to the observatory competition at that time. Pocket watches (large size) and watches (small size), and 30MM is just the dividing line between pocket watches and watches. In other words, 30MM was the maximum diameter limit for watches at that time. His designer was Henri Kneuss, who was already famous at the time, and, This movement received the guidance of Henri Gerber, the second generation godfather of OMEGA. Before his design, OMEGA's main opponents in the observatory watch competition were ZENITH and LONGINES, and his birth completely made ZENITH and LONGINES inferior/His performance Dominated all tests, including at Neuchatel, Geneva and KEW (the only "open" competition, where he broke all records in 1940, 1946 and 1949). In the 1951 GENEVA competition, the 30MM achieved the highest score of 870.3 for a watch, and this score has not been broken to this day! ! From 1938 to 1964, a third of the observatory certificates were awarded to 30MM.

It is recommended by experts as one of the most collectible cores. It has unusual adaptability, excellent calibration performance and easy maintenance. The application of ideal and appropriate components is a reasonable explanation for its top quality. The diameters of the barrel and balance wheel are designed to be as large as possible to achieve first-class adjustment. The most efficient power transmission comes from the strict control of the size of the gears: the smallest escapement is used in the high-quality movement. Starting in 1943, the then extremely fashionable Incabloc shock absorbers were installed above all balance wheels. Later, the anti-magnetic hairspring was also used in the non-breakable series. The 30mm movement was a milestone in watchmaking for a quarter of a century from 1939 to 1963. As evidenced by the fact, its largest user is the British army. The British Army and Navy in World War II were equipped with military watches as good as those of the Royal Air Force pilots (a total of 110,000 watches, more than half of their total sales in Switzerland). 30MM has a 26* series of small three needles and a 28* series of large three needle structures. The former is 260-269 and the latter is 280-286. The specific difference is only in the very small number of diamonds and other subtleties. It should be noted that 262 and 281 are COSC grade and have a large eccentric gong wire fine-tuning device on the swing plywood. The market price is much higher than that of ordinary models. The version of 30T is as follows: New name Old name Diameter High amplitude Stone number Remarks 303041800015 First generation 30MM.

The chronometer 321 of Wanli Searching for the Marquis: Production Year: 1946- 1968 Production quantity: more than 40,000 Designer: Albert Piguet Indicators: Diameter 27mm, back 6.74mm, 17 diamonds, swing 18000A/h Power reserve: 44 hours 321 stopwatch movement Designer: AlbertPiguet321 The beauty of the star column wheel and the beauty of the Y-shaped splint , not comparable to the later 861. The longitudinal wheel gives people a sense of nobility and complexity. Just like a balance wheel with a bare balance wire. The Y-shaped splint with elegant curvature neutralizes the parts of the overall complex timing system. It gives people softness, and most importantly, it gives people a feeling of commanding the overall situation on the assembly surface. Some people often ask whether column wheels are more durable than eccentric wheels. But it seems that friends who are familiar with watches agree that they like the column wheel format. The release of the 321 is comparable to the Type 72 marked with a V in both aesthetics and practicality.

The later 861 used an eccentric design, and the beautiful Y splint was also changed beyond recognition. It is not comparable in appearance, although for many people, it is cheaper and easier to repair. The standard version of the movement was released in 1942 Released, jointly developed by Omega's Jaques Reymond and Lemania's watchmaker Albert Piguet, model 27CHROC12. Later, in 1946, OMEGA changed it to CAL.321. Initially, it was only assembled on SEAMASTER, that is, We often refer to the Seamaster Chronograph Edition. In 1957, the first Speedmaster was put into production. The story that followed was that NASA selected several popular chronograph models on the market (note that they were not custom-made but civilian versions). At this time, OMEGA won the competition with ROLEX, LONGINES and other brands, and was fortunate enough to participate in many NASA missions. On July 21, 1969, Apollo 11 landed on the moon, and the Speedmaster became the first to land on the moon. The watch of the moon, this movement has truly shaped a classic OMEGA series: the Speedmaster series. 4. The fully automatic 561 from Da Jiangdong: Production Year: 1958-1969 Designer: Marc Colomb Production Quantity: 1 million indicators : Diameter 27.9mm, thickness 5.55mm, 24 diamonds, swing 19800A/h, power reserve: 48 hours Chronometer This is the last glory of OMEGA's pre-quartz era - fully automatic series. Starting from the 25MM 470 series and 490 series three needles in 1955, and ending with the 27.9MM 752 dual calendar in the 1970s, OMEGA has had too many brilliance in its more than 20 years of history. Too many observatory certificates, too much market praise and share, too much fame and pride. After that, OMEGA's decline also directly affected the fate of this century-old factory. In the past 20 years, the most famous and mature product among them is the 5 series. Among them, the ones with COSC certification are 551, 561, 564, and 751. In terms of time, 551 without date display is earlier than 561. In terms of structure, the 564 with a date jump is more advanced than the 561. But you must know that the reason why a product becomes a milestone is not because it is advanced. Because, the most pleasing appearance of the constellation is the curved ear bagua face, and the most mature and most popular products equipped with the curved ear bagua face, namely 561, 564 and 751, most of them already have a sense of the times in the 1970s in terms of the shape of the casing. Its value is not as high as that of a bent ear. Judging from the second-hand market, 561 is well preserved and extremely beautiful. The coating of the movement is the iconic color of OMEGA's mid-term: rose gold. The pendulum connected by the pin rod is extremely flexible and durable. Together with the gooseneck device that can fine-tune the speed, the usability and beauty of the entire movement are fully utilized. . In the current second-hand market, there are many people playing with the 5 series, but most people are not able to distinguish the material difference between the hairspring and balance wheel of the COSC grade 561 and the ordinary grade 562. Should know. The COSC level is not only more complex in adjustment, but also more professional in the selection of materials. As a result, there are many things in the world that use 562 or 565 to pretend to be COSC level 561. The differences between common movements in the 5 series are as follows: no date date slow adjustment date fast adjustment date/day 17 diamonds 55056056375024 diamonds 55256256575224 diamonds chronometer 5515615647515.
