Identification of watch is actually a chapter. Watch is different from the calligraphy and painting and porcelain, because the clock itself is a sophisticated machinery, some even very small fine, false process could not trail. Do fake mainly cover don’t understand, false and true omega seamaster 300 omega seamaster 300 is not likely to do exactly the same. Below we specific introduced some methods to identify watches authenticity. , of course, also need to know more about how to study, to see more research and identify the ability of the natural is improved.
A. The machine core components:
(1) from the machine surface
Some important machine parts, on the surface, are easy to see such as: pendulum splint on shock absorbers. There are different firms, have different grade, low common with triangle shock absorbers, fake watch to see more. Better use INCBLOC, high-grade watch and general use KIF shock absorbers, such as ROLEX ROLEX, vacheron constantin, patek philippe, Abby, watch carefully you will find that even with the same movement, on the specifications of the shock absorbers are also different. Such as OMEGA OMEGA and emperor tuo TUDOR are using the ETA 2892 movement, but use KIF TUDOR, OMEGA INCBLOC, high-grade tradition, high-grade watches usually KIF shock absorbers and the precision of a worm type adjustment structure (called “hanging”), is a sign of high-grade watch movement, at least with eccentric ROM nail trimming mechanism.
(2) material process:
In addition, it’s easy to see the parts are the escapement wheel and tackled longitudinal fork, movement of the medium using copper escapement fork, escapement wheel and escape are polished surface longitudinal fork, high-grade machine core using steel pallet fork, (because the low proportion of steel) escapement wheel and tackled both longitudinal fork surface polishing, polishing steel parts, machine core plywood done decorate and grinding is an important characteristic of high and low omega seamaster 300 movement.
Balance wheel: the balance wheel of high-grade omega seamaster 300 must BE golden, but the balance wheel material is not the same, the general omega seamaster 300 with copper zinc alloy (silver) in Germany, high-grade with beryllium alloy beryllium (BE) is a kind of aviation materials, light and hard, mainly small temperature linear expansion, can guarantee the accuracy of watches.
High-grade omega seamaster 300 has Geneva signal (12).
Movement on the surface of the color:
Common mainland goods movement (including quartz) have ETA, RONDA about, Japan (MIYOTA) is a citizen, on general machine core plywood with SWISS PARTS, usually in the far east assembly (Thailand) movement, and plywood gilded machine core is mostly origin.
(3) movement splint identification:
In the past a lot of watches are produced machine, such as: product family, the movado, OMEGA, OMEGA, British nagl ENICAR, LONGINES LONGINES called “universal omega seamaster 300 factory”, and now in order to control the cost, are buying machine, main is to use a Swiss ETA movement. (the original Swiss there are a lot of movement factory, ST, the AS, FHF, F, but difficult to see now.)
Almost with RONDA about (quartz), everyone is using the ETA, to distinguish, mainly in the automatic tuo engraved on their own. Because the automatic is the proportion of larger metal, stamping lettering. Quartz watch is on the circuit board to print their own brand, kadeya also use ETA, but it has its own special plywood.
Furthermore, mechanical watch movement on the bottom plate of the edge of the balance wheel position typically has a set of special letters.
Each omega seamaster 300 has its own standard, so, change the heart save a omega seamaster 300, can also be seen.
Again, there are some famous large omega seamaster 300, also can use ETA movement, but often it is another to do a fine processing (grinding). There is also a feature is their named machine core number, such as longines, radar, the nag, (such as the British nagl ETA 2671, machine core plate engraved with “AR 770”, it had an announcement, if there is no movement floor AR. Is fake watch!)
2. Look at the label
Some watches have colorful label on the back cover: for example, ROLEX, false omega seamaster 300 is a piece of green paper, there is no iridescence effect, early plum TITONI iridescence label on the back cover do quite well.
3. See subtle appearance:
So-called slight place main dial, whose hands the most telling of false omega seamaster 300 pointer rarely do good, such as the needle under the flag of suspension, needle, brightness is bad, the needle Angle is not clear. Second hand tail as ROLEX is a circular arc, and false omega seamaster 300 is flat, and some of the quartz watch second hand in order to balance, the tail is upset and so on.
See omega seamaster 300 card and English marks, scale. Printing is very unique, like ROLEX paint is very light, also printing is very high. Do not fake watch this. Often see some fake ones such as ROLEX and PIAGET not only printing fuzzy and not fully covered. Watch dial cannot do false lifelike, ROLEX computer disk technology is complex, it is hard to make it real.
4. See the surface of glass
Surface glass production level is very high at present, general fake watch and watch, just some brands of watches on the glass. Like the early OMEGA, Rome. Now the ROLEX in glass 6 point also have standard, is a small line of ROLEX English letters.
A ROLEX Sapphire glass factory in shenzhen to buy only about 20 yuan, and the original of about 1500 yuan. Glass is the sapphire, the appearance difference is not big. (slightly blue. Really false is colorless) but not quite the same as the nylon ring.
Sheet glass materials are: early plastic (organic), mineral and sapphire. Sapphire glass in common now. (Sapphire) Sapphire also specifically noted in the past, fake watch superscript Sapphire Sapphire can rear cover, and use common glass. This refractometer can be used to check out. Sapphire refractive index is 1.76 to 1.77, and the glass is 1.52.
5. See number digital identification:
Generally watch has watchcase model and the movement model, the production of high-grade watches should have omega seamaster 300 number, machine core production serial number and strap, inside and outside of the tags on the back cover. In addition, some omega seamaster 300s of earmuffs strap inside and outside has number.
Fake ones have a mark, also have a mark. Observe, however, fake watch of dozen of lighter, have a plenty of crooked carved up, have a plenty of word size is wrong, or incompliance watch coding rule or digital digits long. , ROLEX, TUDOR production serial number is a letter and 6 digits, and OMEGA and RADO is 8 digits. Found false radar have 13 digits, and the stamping on the back cover, that means doing thousands of watch is likely to be a number.
The serial number of each type of watch also have its meaning, not write. Such as ROLEX, 16233:16 is automatically male omega seamaster 300 calendar, and 18 is automatic double male omega seamaster 300. Mantissa is golden add to digest steel for 3, mantissa is 8 is gold, 4 are all steel + platinum ring, with a tail of 0 is stainless steel shell, etc. And many false omega seamaster 300 is write. Each word is really independent number only.
Some generic DE nice OMEGA, OMEGA, also use ETA 2892 movement, and really just automatically tuo lettering marking is very strange, like a laser engraved. Bottom plate of the standard are intentionally milling, no movement.
About Japan’s omega seamaster 300. According to Japanese CITIZEN information note: every movement automatically tuo is not carved on the CITIZEN, but time is not original CITIZEN MIYOTA, export is CITIZEN MIYOTA movement, and there’s no gold-plated splint.
Many false omega seamaster 300 is done with the old machine is put into a generic new shell, the movement after a lot of maintenance, surface parts and splint has minor scratches, screw specification is not unified, the most easy to find is screw rabbet flanging and squeezed.
6. See the icon
See chart mark mainly K gold and assaying the omega seamaster 300. Fake ones usually do mark, lighter, and even many times stamping don’t overlap. The mark of the true omega seamaster 300 is really deep and clear. Tags usually play inside and outside the back cover and omega seamaster 300 and strap on the claws, leather strap on the ring.
With gold plated case as K gold or stainless steel shell shell, it can only play 18 K, but can’t type icon, can feel with the hand is not the same as the proportion of the two. Fake watch back cover to do is very thick, and even on the back cover and lead weights. Stainless steel is weak magnetic material, but also attracted to strong magnetic field, the omega seamaster 300 with a rope tied to hang, use aluminum iron boron to suck.
If it is gold plated watch case, the thickness of more than 10 microns, also must have looked. Such as, G10, PL10 PLATED10. Like OMEGA OMEGA gold-plated 20 microns, in the case of shell with a 20 claws, less than 10 microns gold-plated omega seamaster 300 is only low.
7. Look at the diamond and the embedded technology
Fake watch dial with diamond, artificial zircon. Or even with natural diamond, but of rough, uneven size, diameter of big or small, have broken phenomenon. Generally do not use high-grade watch diamond, because use high-grade precious metals and stones to show.
Eight. Look at hidden places:
In the identification of more professional level, to remove the appearance and procuratorial machine core components, such as the improper eye: strap, the nail, casing, strap section. Because even the best cooking, don’t do these places of these components have obvious different original omega seamaster 300.
Such as 16238, the rolex watch case strap are 18 k gold, false and true omega seamaster 300 can do, however, is less weight 2 grams, why? Strap section process do not like. Also include the most common 16233, too. Rolex before K gold ring is a crown of mark, tear open come down to see. Fake ones.
omega seamaster 300 with a spring (with spring is elastic fittings) connected to the case and strap elastic bolts. With spring is generally purchased fake watch, and true omega seamaster 300 is different. Typical is ROLEX ROLEX watches. Bring the omega seamaster 300 look here first, is essential to know. And radar, such as OMEGA with spring is special, fake do vary wildly.
In addition, the handle of true omega seamaster 300 false omega seamaster 300 head tube also have very big distinction, the installation process is different also. If it is K gold watch the grip tube is golden, whereas false omega seamaster 300 may be steel color, generally no inner gear. This can be pulled out a omega seamaster 300 to see.
