Many people know that the watch 8200 movement is a famous movement of the west railway city.
But all say only all say only Tuo is gilded is true.
Can also have a friend to buy the watch, 8200 movement tuo is steel.
So Xiaobian to introduce the method: the west Tiecheng watch automatic double calendar, the use of 8200 movement, the output is very large, it is 21 drill, 21600A/H swing frequency, pan incense spring type shock absorber, one-way automatic winding, but can be hand string.
As early as more than 30 years ago there is this movement, so it is a “grandmother” class of old movement, at the same time it is also a large number of exports, but automatically don’t play the logo, and play MIYOTA’s standard, the movement is not gold plated, including the West iron City watch all kinds of quartz movement is also this regulation.
This movement also has the domestic imitation, the work is more rough, widely used in low grade watches.
30 years ago, the workmanship of the watch is OK, including all the exterior parts are all made in Japan.
Now the “close to the people” class watches are not as fine as the early years, belongs to the “weasel under the pups – a litter as a litter”, the natural price has risen a lot, feel the main direction of the west iron city watch is now light kinetic energy and radio watches, there are some with complex functions of high-end watches.
West Tiecheng watch false table most, have long since, now make false craft level has also improved, case, dial, hand and watchband do well, so not as before, only by the appearance of the production of fine to judge the authenticity.
West Tiecheng watch the earliest to determine the authenticity of the method, the most important is to see the identity of the movement, all watches with MIYOTA mark, will be considered false table.
But now it is easy to make a new automatic instrument with Citizen mark on the fake watch, and then plating the surface with gold, so this trick is not working.
Therefore, the Japanese secretly added some code, so as to distinguish and identify, that is, on the back of the automatic tuo stamp marks, generally a small circle with numbers or letters, also see graphics, is a rectangular box, full of XXXX marks.
8200 machine center automatic Tuo shape is not the same, the earliest is face shape Tuo (Tuo surface belt used as the notch of shock absorber arm), later changed to “mountain” shape tuo, is tuo along the downward Tuo axis hole up to see positive, and Tuo surface MIYOTA letters, are printed with black paint, carefully to distinguish,
The position of the arrow and the direction of the letter looking positive are non-standard or opposite.
Repair computer maintenance workers, also divided into “card” level and “component” level, so can start from the decomposition of parts, pay attention to observe, the former 8200 movement, its shock absorber spring is gold plated, now are not gold plated;
Spring is also the most important part of the watch movement, the characteristics of the Japanese watch is to make the spring box sealed, is not to let you open, and is good at using a black lubricating oil in automatic parts or spring, that is called “molybdenum disulfide”.
Japanese watch is the west iron city, Swiss watch is a Tissot, are more chaotic, you take the watch to manufacturers or business offices, they can only see the characteristics of the machine center is consistent, a little “false do true true also false” embarrassing situation.
There are also a large number of authorized assembly in China, such as in Beijing Jiuxianqiao there is a watch assembly factory, the rest of the shanzhai or underground workshops are estimated to be more, leading to the current situation, the root cause is the manufacturer, in the prevention of counterfeiting and anti-counterfeiting means of inaction.
The latest market dynamics at any time to see, please pay attention to.
