1. Look at the appearance: Longines watches generally have case models and movement models. High-end longines watches should also have production serial numbers, movement production serial numbers and strap numbers. These marks are located inside and outside the back cover of the watch or in special positions. Fake watches may also have these marks. However, after careful observation, it will be found that the marks of fake watches are relatively shallow, some are obliquely engraved, some are different characters or sizes, or do not conform to the coding rules or digital digits of this Longines watch.

2. Look at the movement: Many fake watches are put into imitation new shells with old movements. These movements have been repaired many times, and the surface parts and splints are slightly scratched, and the screw specifications are not uniform. The most easy to find is the indelible mark caused by the extrusion of screw notch flanging. The pendulum needle in the genuine Longines watch movement has brand words, the interior is clean and the parts are stable. On the contrary, if there is no brand word or fuzzy skew on the pendulum needle of Longines watch, it is probably a fake.

3. Watch hands: Watch hands can give users one more criterion to judge, and watch hands of fake watches are rarely good. For example, where the needle flag hangs down, the needle is uneven, the brightness is not good, and the edges and corners of the needle are not clear.

Precautions:

Waterproof, any watch hates water, and it is easy to rust, stink and fog. Sweat is even more so.

Please don't open the back cover of the watch at will to avoid dust entering the movement and affecting the normal work of the watch. Without technology, you have to turn it off if you open it.

Don't put your watch and mothballs together in the wardrobe to avoid oil deterioration. Other chemicals should also be avoided.
