[Watch Wikipedia] how to identify the authenticity of the watch?
In fact, there is a chapter identified the watch to be found . Unlike paintings and porcelain watches because watches itself is a sophisticated mechanical devices, some even very small fine , fraud could not have eluded capture process . Fraud is mainly Mongolian people do not understand , leave the table and really can not do exactly the same table . Here we introduce to you some of the specific identification method for the authenticity of the watch . Of course, also need to know more about the multi- study , to see more studies , ability to identify the naturally increased.
One . Movement components:
( 1 ) from the surface movement
Some important parts of the movement , on the surface, put plywood on such relatively easy to see : shock absorber . There are different names, different grade and low-grade common triangular shock absorber , leave the table to see more. A little better with INCBLOC , and high-end watches generally with KIF shock device , such as Rolex ROLEX, Vacheron Constantin , Patek Philippe , love them , look closely you will find that , even with the same movement, shock absorber specifications are different for example OMEGA OMEGA Dili Tuo TUDOR use the ETA 2892 movement, but TUDOR with KIF, OMEGA with INCBLOC, there are high-end luxury watches traditional practices , often KIF shock absorber and one worm -like precision adjustment structure ( called the " Austrian vertical Manchester " ) portfolio , is a sign of high-end watch movement , at least the eccentric Luo nail trimming body.
( 2 ) Material Process:
In addition , it is easier to see the parts are escapement wheel and escapement fork, middle and low movement using copper escapement fork, escape wheel and escapement fork surfaces are not polished , high-grade steel for use escapement movement fork , ( because the low proportion of steel ) escapement wheel and escapement fork surfaces are polished , polished steel parts , plywood make modifications and grinding movement is a major feature of the level of table movement .
Balance: The balance sheet is definitely upscale gold , in fact, the material balance is not the same , the general table with the zinc and copper alloys ( German silver ) , high-end (BE) is a beryllium beryllium alloys aviation materials , and light and hard , mainly small linear expansion temperature change , to ensure the accuracy of the watch .
High-end table with the Geneva mark ( 12 requests ) .
Movement of surface color:
Common mainland goods movement (including quartz ) has ETA, RONDA, Japan (MIYOTA) is the Citizen , engraved with SWISS PARTS general movement plywood , general assembly of the Far East (Thailand ) movement, while plywood gilded movement mostly origin .
( 3 ) the identity of the movement plywood :
Many watches are self-produced movement in the past , such as: Jaeger-LeCoultre , Movado , Omega OMEGA, Enicar ENICAR, Longines LONGINES , etc. is called " Almighty watch factory ", and now in order to control costs, are buying movement, mainly use Swiss ETA movement. ( There are a lot of original Swiss movement factory , ST, AS, FHF, F, but basically did not see it. )
Almost by RONDA ( quartz ) , we are using the ETA, in order to distinguish , mainly engraved own mark on the automatic Tuo because automatic Tuo is relatively large proportion of metal , not stamped lettering . Quartz watches is on the board print your own card table , Cartier also used ETA, but it has its own special splint.
In addition , the mechanical watch movement of the main plywood placed in the position of the edge of the wheel will generally have a special group of letters.
Each table has its own standard , so the movement to save another table , can also be seen.
Again, there are a number of brand-name large table , also use ETA movement, but usually do some other fine processing ( grinding ) . Another feature is the movement named after his number, such as Longines, Rado , Enicar , ( eg Enicar ETA 2671, floor movement engraved "AR 770", which had been an announcement if there is no movement of the floor the AR. statement is false ! )
Two . Read labels
After some watches cover with Symphony labels : for example , ROLEX, leave the table is a piece of green paper , Symphony no effect , after the early plum TITONI cover Symphony label is also doing quite well.
Third, look at the appearance of fine places:
The so-called minor key local dial, hands in the process that best describes the problem , leave the table pointer rarely done well , such as a place where the flag hanging needle , needle uneven brightness is not good, the needle edges are not clear. The tail is like second hand ROLEX arc , and leave the table is flat, and some quartz watch second hand for balance , the tail is thick and so on.
Look at the table and the English brand identity, scale. Like ROLEX printing is very unique, very bright paint , also printed high. This point can not leave the table . Often see some of the false statement as : ROLEX and PIAGET only vague and can not be printed completely covered. Watch dial is not realistic fraud , ROLEX computer disk complex process, it is difficult to make really fake that.
Four . Look at the surface of glass
Glass surface current production levels are high, generally leave the table and the table is almost true , but some brands of watches marking on the glass . As early OMEGA, Rome. And now the 6 o'clock position on the glass ROLEX also standard, is a small line of ROLEX English alphabet.
Sapphire glass to buy a ROLEX of about only 20 yuan in Shenzhen factory, while the original is about 1,500 yuan. Glass is sapphire , not very different appearance . ( Really a little blue . Fake colorless ) , but not the same nylon ring .
Sheet glass material: plastic early ( organic) , mineral and sapphire . Now Sapphire glass is very common. Also particularly marked in the past (Sapphire) Sapphire , leave the table can be covered with standard Sapphire Sapphire , but with ordinary glass . This refractometer can check it out . Sapphire refractive index is 1.76-1.77 , while the glass is 1.52 .
Five- digit identification number to see :
Appearance:
General Case Model and movement watches have models, as well as the production of high-end watches should table number , serial number and strap movement production numbers, these markers hit the table and outside back cover . Further, the inner band of the outer ear have some form p .
There is no marking leave the table , there are marking . However , to observe , mark off the table playing relatively shallow, carved up some crooked , some code size is wrong, or does not comply with the law or digital watches encoded digits long . (ROLEX, TUDOR production number begins with a letter followed by six digits, while the OMEGA and RADO are eight digits. Discovered false radar has 13 digits , and is stamped on the back cover , it means doing thousands only the table may be a number.
Each watch also has a number of meanings , not scrawl . Such as ROLEX 16233:16 automatic calendar male form, while 18 is the automatic double calendar male table . Ending in 3 gold plus steel , ending in 8 gold table 4 is steel + platinum ring, ending in a stainless steel shell with 0 and so on. And many of them are fake table scrawl . Each table is really individually numbered .
Movement
Some very good imitation of the German Omega OMEGA, also used and really like the ETA 2892 movement, just a standard automatic Tuo lettering is very strange, like a laser engraved . Primary standard is intentionally plywood mill go, no movement that letter .
On the Japanese table . According to Japan's Citizen 's Information Note: Where automatic tourbillon movement is not engraved on CITIZEN, but not the original engraved MIYOTA the Citizen , MIYOTA is Citizen export movement, and there is no gold-plated plywood .
Many false tables are loaded with old imitation of new housing movement , these movements after several repairs, parts and plywood surfaces have subtle scratches, screw specifications are not uniform , is most easily found the screw slot flanging and extrusion.
VI. Looking icon imprint
See chart imprint mainly K gold and fineness of the table . Leave the table usually do mark vague , relatively shallow, even repeatedly punching not coincide. Table is really really deep and clear imprint . Mark usually hit the back cover and outside tables claw and strap , leather strap hit the buckle .
With gold-plated stainless steel case or shell posing K gold shell , only play 18K, but can not play icon , you can feel both hands is not the same proportion . Cover intentionally made a false statement is very thick , and even add lead weights in the back cover . Although stainless steel is weak magnetic material, but will be attracted strong magnetic field , the table with a rope tied to hang up, with aluminum and iron boron to suck .
If it is gold-plated case, thicker than 10 microns, must also have a digital standard . If G10, PL10 PLATED10. Like OMEGA OMEGA 20 micron gold plated , in the case of the shell is marked with a claw 20 , less than 10 micron gold plated table can only be considered a low gear .
VII. Look diamonds and mosaics
Fake watch dial water drilling , artificial zircon. Or even natural diamonds, but inlaid injustice, unequal size , diameter , large or small , have broken phenomenon. Luxury watches generally do not use stones, because the use of precious metals and stones to significantly upscale .
VIII. Look hiding place :
More professional level of identification, to demolish the appearance and movement parts prosecution, such as the most inconspicuous place: strap worn nails, casing, strap section . Because even the wisest false nor do these places, where these parts have distinct original table.
Such as Rolex 16238 , case strap are 18K gold , false and true statement can do the same, however, is two grams less weight , why? Band Festival craft to do the same . 16233 also includes the most common , as well. Circle K gold Rolex before there is a subject of the crown , removed to see . Leave the table does not.
Table with a spring ( with spring is elastic connector ) to connect the elastic case and strap bolt . Leave the table with a spring is generally purchased , so the table and really different . Typical is ROLEX Rolex watches . The table used to look here , you basically know eighty-nine it. There are radar , OMEGA , etc. are specially designed with a spring , fake do different.
In addition, the table leave the table really handle head tube is also very different , the installation process is not the same . If K gold watch is golden handle head tube , and leave the table may be a steel -colored , generally do not have the teeth . This table can be pulled out to see.
