The anti-counterfeiting and anti-counterfeiting mark of the Rolex 18K solid gold single calendar is under a diamond in the middle. The dark blue film on both sides of the dial means that it has not been used. The blue film is also an anti-counterfeiting mark. Once used, it will be Unable to recover! There are authentic Rolex and 18K real gold trademarks on both sides of the dial.

The genuine Swiss original movement can be inspected by any regular watch shop. The gold watch strap inlaid with real 18K gold bars, 18K gold ring, and 18K real gold hands can be inspected by any regular gold shop.

There are actually rules to follow when appraising a watch. Watches are different from calligraphy, painting and porcelain, because the watch itself is a sophisticated mechanical device, and some are even very tiny and delicate. It is impossible to fake the craftsmanship without revealing flaws. Counterfeiting is mainly done by people who don't understand, and it is impossible for a fake watch to be exactly the same as a real watch. Below, Aibiao.com (www52watch.com) will introduce you to some specific methods to identify the authenticity of watches. Of course, you also need to know more and study more. The more you read and study, the ability to identify will naturally improve.

1. Movement parts:

(1) Looking from the surface of the movement

Some important movement parts are easier to see on the surface and on the swing plywood, such as the shock absorber. There are different brands and different grades. Triangular shock absorbers are commonly used in low-end products, and fake ones are more common. Better ones use INCBLOC, while high-end watches generally use KIF shock absorbers, such as Rolex, Vacheron Constantin, Patek Philippe, Audemars Piguet, etc. If you look carefully, you will find that even if they use the same movement, the specifications of the shock absorbers are different. For example, both OMEGA and TUDOR use ETA 2892 movements, but TUDOR uses KIF and OMEGA uses INCBLOC. High-end watches have high-end traditional methods, usually KIF shock absorbers and a worm-type precision adjustment structure (called "Austria"). "Trist") combination is the hallmark of high-end watch movements. At the very least, it is a fine-tuning mechanism using eccentric rivets.

(2) Material technology:

In addition, the easier-to-see parts are the escape wheel and escapement fork. Mid- to low-end movements use copper escapement fork. The surfaces of the longitudinal wheel and the pallet fork are not polished. High-end movements use steel pallet forks. (Because the specific gravity of steel is low) the surfaces of the escape wheel and pallet fork are polished. The steel parts are polished and the movement plywood is made of steel. Finishing and grinding are a hallmark of high-low watch movements.

Balance wheel: The balance wheel of high-end watches must be gold. In fact, the materials of the balance wheels are different. Generally, zinc-copper alloy (German silver) is used for watches, and beryllium alloy (BE) is used for high-end watches. It is an aerospace material that is light and hard. It mainly has small changes in temperature linear expansion and can ensure the accuracy of the watch.

High-end watches have the Geneva mark (12 requirements).

Color of the surface of the movement:

Common mainland movements (including quartz watches) include ETA, RONDA, Japan (MIYOTA) is Citizen, and the general movement is on the plywood Engraved with SWISS PARTS, it is usually a movement assembled in the Far East (Thailand), while most movements with gold-plated splints are of original origin.

(3) Identification of the movement splint:

In the past, many watches produced their own movements, such as: Jaeger-LeCoultre, Movado, OMEGA, ENICAR, and Longines Longines and others are called "all-round watch factories", but now in order to control costs, they are buying movements, mainly using Swiss ETA movements. (There used to be many movement factories in Switzerland, such as ST, AS, FHF, and F, but now they are basically invisible.)

I almost used RONDA (quartz watch), everyone uses ETA. In order to distinguish, mainly It is to engrave your own logo on the automatic rotor. Because the automatic rotor is a metal with a relatively high specific gravity, it cannot be stamped or engraved. A quartz watch prints its own watch plate on the circuit board. Cartier also uses ETA, but it has its own special plywood. . In addition, mechanical watches usually have a set of special letters on the edge of the balance wheel position of the main plate of the movement. Each watch has its own mark, so if you buy a watch with a different movement, it can be seen.

Furthermore, some famous brand watches will also use ETA movements, but usually require additional fine processing (polishing). Another feature is to name the movement number yourself, such as Longines, Radar, and Inager, (for example, Inager ETA 2671, the movement bottom plate is engraved with "AR 770". It once had an announcement that if there is no movement bottom plate AR. It’s a fake watch!)

2. Look at the label

Some watches have a magic label on the back cover: for example, ROLEX, the fake watch is just a piece of green paper without a magic effect, the early Plum Blossom TITONI has a magic label on the back cover Pretty good too.

3. Look at the subtle details of the appearance:

The so-called subtle points are mainly the dial and the craftsmanship of the hands. The hands of fake watches are rarely made well, such as the needle flag hanging down and the needle being uneven. , the brightness is not good, and the edges and corners of the needle are not clear. For example, the second hand of ROLEX has a rounded tail, while the fake watch has a flat second hand, and some quartz watches have a thickened second hand for balance, etc. Look at the dial, English logo and scale. The printing like ROLEX is very unique, the paint is very bright, and the printing is very high. Fake watches can’t do this. It is often seen that some fake watches such as ROLEX and PIAGET are not only vaguely printed but also cannot be completely covered. The dials of famous watches cannot be faked to be lifelike. ROLEX's computer dials have complex craftsmanship, so it is difficult to make fake ones look like real ones. Four. Look at the surface glass

The current production level of surface glass is very high. Generally, fake watches are almost the same as real watches, except that some brands of watches have markings on the glass, such as the early OMEGA and Rome. The current ROLEX also has a mark on the glass at 6 o'clock, which is a very small line of ROLEX English letters. A piece of ROLEX Sapphire glass costs about 20 yuan at a Shenzhen factory, while the original one costs about 1,500 yuan. The glass is all sapphire, so there is not much difference in appearance. (The real one is slightly blue. The fake one is colorless) But the nylon seal is different.

The materials of watch glass include: early plastic (organic), mineral and sapphire. Sapphire glass is now very common. In the past, sapphire was also specially marked. Fake watches can be marked with Sapphire on the back cover instead of ordinary glass. This can be checked with a refractometer. The refractive index of sapphire is 1.76-1.77, while that of glass is 1.52.

5. Look at the number identification:

Appearance:

Generally, watches have case models and movement models. High-end watches should also have the production serial number of the watch, the movement production serial number and the movement model. With numbers, these marks are stamped on the inside and outside of the watch case back. In addition, some watches also have numbers on the inside and outside of the ear protectors. There are fake watches that are either marked or not. However, if you pay attention, you will find that the markings on fake watches are relatively shallow, some are engraved crookedly, and some have the wrong size of characters, or do not comply with the coding rules of the watch, or the number of digits is too long. (ROLEX and TUDOR production serial numbers start with a letter followed by 6 digits, while OMEGA and RADO are both 8 digits.

It was found that the fake radar has a 13-digit number, and it is stamped on the back cover, which means that thousands of watches may have the same number. The number of each watch also has its own meaning and is not written randomly. For example, ROLEX 16233: 16 is an automatic calendar men's watch, and 18 is an automatic dual calendar men's watch. The number ending in 3 is gold plus fine steel, the number ending in 8 is a gold watch, the number ending in 4 is an all-steel platinum ring, the number ending in 0 is a stainless steel case, etc. Many fake watches are written randomly. Genuine watches are each individually numbered.

Movement

Some replicas of the very good Omega OMEGA also use the same ETA 2892 movement as the real one, but the engraved mark on the automatic rotor is very weird, like a laser Engraved. The markings on the main plate are intentionally milled away, and there is no movement letter. About Japanese watches. According to information from Citizen Japan, any movement with an automatic rotor that is not engraved with CITIZEN but is engraved with MIYOTA is not an original Citizen. MIYOTA is an exported movement from Citizen and does not have a gold-plated splint. Many fake watches use old movements and put them into imitation new cases. These movements have been repaired many times. There are minor scratches on the surface parts and plywood. The screw specifications are not uniform. The easiest thing to find is the notch flanging of the screws. and squeeze.

6. Look at the icon marks

Look at the chart marks mainly for K gold and fineness tables. The marks usually made on fake watches are blurry, shallow, and even do not overlap after multiple stampings. The real watch has a very deep and clear imprint. Markings are usually stamped on the inside and outside of the case back, on the prongs and strap, and on the leather strap buckle. Use a gold-plated watch case or stainless steel case to pretend to be a K gold case. It can only print 18K, but cannot print the icon. You can feel the different proportions of the two with your hands. The back cover of fake watches is intentionally made very thick, and some even add lead weights to the back cover. Although stainless steel is a weak magnetic material, it will also be attracted by strong magnetic fields. Hang the watch with a rope and use aluminum iron boron to attract it. If it is a gold-plated watch case and the thickness exceeds 10 microns, it must also have a number mark. Such as G10, PL10 PLATED10. For example, Omega OMEGA has 20 micron gold plating, and there is a 20 mark on the claw of the watch case. Gold plating below 10 micron can only be considered a low-end watch.

Seven. Look at diamonds and inlay techniques

The dial of the fake watch is made of rhinestones and artificial zircon. Or even if natural diamonds are used, the setting is uneven, uneven in size, large or small in diameter, and broken. High-end watches generally do not use rhinestones, because precious metals and gemstones can look high-end.

8. Look at the hidden places:

For more professional-level identification, you need to disassemble the appearance and movement components to inspect, such as the most inconspicuous places: strap nails, sleeves, and strap joints. Because even the most sophisticated counterfeiters do not do these things, these parts are obviously different from the original watch. For example, Rolex 16238, the case and strap are all 18K gold. The fake one can be made the same as the real watch, but the weight is two grams less. Why? The strap joints are made differently. Also includes the most common 16233, as well. Rolex's K gold front bezel has a crown mark, which can only be seen after it is removed. Fake watches don’t.

The strap spring of the watch (the strap spring is the elastic connector) is the elastic bolt that connects the watch case and the strap. The springs of fake watches are usually purchased from outside, so they are different from real watches. A typical example is ROLEX. Take the watch and look here first, and you will basically know eight or nine. Also, the belt springs of radar, OMEGA, etc. are all specially made, and the fake ones are made very differently.

In addition, the crown tubes of real and fake watches are also very different, and the installation process is also different. If it is a K gold watch, the crown tube is also gold, while a fake watch may be steel-colored and generally has no internal teeth. This can be seen by pulling out the crown of the watch.
