The crash caused multiple core failure at first reading switzerland's 2824 core, which was confirmed as a domestic counterfeit
The multiple purchase of the yada mechanical watch caused a strike on the core due to a heavy fall, the automatic bearings were completely dispersed, the rollers fell inside the core, and the wheel-top drill was damaged. When the core was first seen, the automatic deck was designed with a swiss eta 2824 signature gap, and it was once mistakenly assumed that the original swiss core had been loaded on board and that it was not identified as a nationally produced 2824 core, as opposed to the original eta 2824 core, depending on the roughness of the parts and the characteristics of the component process, until it was carefully checked after the dismantling of the machine。
The core identification is the most intuitive distinguishing point, with hidden parts working to assist in judging the national production and the swiss core of 2824
The distinction between national production, 2824 and the original swiss eta2824 core, is based on a clear and operational judgement, the most visible of which is that of the core to avoid the crater. There are three pits designed for the earthquake-proof location of the original 2824 swiss core, while there is only one pit for the national imitation, so that the naked eye can be clearly identified without the use of sophisticated tools. In addition to this, practitioners who are exposed to the core maintenance throughout the year are able to use the details of the hidden parts, such as the processing precision of the horse's deck, the grinding of screws, the national core and the original swiss core. There are still significant gaps in these areas, and the difference can be seen at once。
3000 u. S. Dollars to fly aada's national production of 2824
This 3000 multi-priced flying yada watch, which uses domestic production to imitate 2824 cores, is a suspect of cost savings, after all, because it is possible to carry the original swiss 2824 core. Differences in the quality of the core, on the other hand, directly determine the differences in the maintenance process, since the maintenance of the national core 2824 is far from replicating the operation for the maintenance of the original swiss core, and there are many details that require special attention, otherwise it is highly vulnerable to secondary damage。
Nationally, 2824 core screws are too strong to break
The primary focus of the maintenance of the national core 2824 is to screw the screw power. The spare parts for the original 2824 swiss core are solid, the hardness and resilience of the screws are excellent, and normal hard wringing during maintenance does not cause any fractures at all; however, the nationally produced screw of 2824 cores, which, once overstretched, can be extremely fractured, can significantly increase the difficulty of repairing the core, which is the most taboo point of repairing such cores, with each of the screws in operation being softly fined。

When no dragsticks are debugged, the crown must be pulled to the re-routing position to avoid the re-entry of the motor
Another key point of attention is the alignment operation without a mop pole, at which point the crown must first be drawn to the date transfer slot. If this step is ignored, direct debugging, it is highly likely that the motors inside the core will be subject to flip-back problems, requiring the removal of the wristwatch shells, which will not only add to the additional maintenance work, but may also cause damage to the surface parts such as the watch casings, palettes, etc. During the dismantling process, affecting the overall shape of the wristwatch and causing additional maintenance problems。
Different quality cores of the same type [maintenance core]. Maintenance processes are not generic and require matching operational standards
The experience with the maintenance of the women's watch in aada again confirms the important principles of wristwatch maintenance: the cores of different quality, of different origin, cannot be generalized, even in the same type, and must be adapted to the corresponding technical standards. The original installed core in switzerland is well-medicated and well-manufactured, with a relatively high margin of error in maintenance; and the national production emulation core deficiencies in detail require maintenance personnel to operate with greater care and care and to exercise precision control over each operational detail in order to avoid unforeseen problems and ensure that the cores function properly。
