2. Judging from the watermark, the original invoice is printed with black and white watermark anti-counterfeiting special paper, and it is obviously concave and convex to touch the watermark by hand. Under the backlight condition, you can see the dark watermark of GDLT English letters and the light watermark of tax emblem pattern, which looks clearer. The watermark on the fake invoice is not very concave and convex. The big difference is the tax emblem pattern, which looks very vague.
3. From the prize area, the cover layer of the regular invoice prize area is laser foil film, which is dull in color and easy to scratch. Fake invoices are difficult to scrape, and sometimes scraping is possible.

Swiss watch identification method:
1, check the appearance of the watch: the Swiss watch case should be angular and symmetrical, without scratches and sand holes, and the back cover and case should be tightened. The two pairs of holes for installing the strap spring should be centered and the depth should be appropriate, so that the watch spring is not easy to fall off. The surface covering should be smooth and transparent, without scratches and defects. The electroplating of dial and hands should be bright, and the minute and second scale lines and luminous points of dial should be completely luminous.
2. Check the sensitivity of the watch: The sensitivity of the Swiss watch means that the balance wheel in the watch will start by itself sooner or later.
3. Check the winding efficiency of the watch: When a normal Swiss watch is wound, the hand should feel loose and tight. When it is not fixed, it means that the spring is full. Such as the abnormal sound of "click, click" when winding, or the phenomenon that the handle shaft slips, all indicate that there is something wrong with the winding part.
4. When the minute hand rotates, check the tightness of the Swiss watch. Turn the minute hand and the hour hand continuously 12 hours. If the minute hand and the hour hand are not obviously loose or tight in each position for 12 hours, it means that the movable part of the watch's hands is installed normally.
5. Check the sound when walking: wind the watch several times and listen to the sound when walking. If the sound is even and clear and there is no noise, there is nothing wrong with the watch, because the quality of the watch mainly depends on the accuracy of the actual walking time rather than the sound. Therefore, listening to the sound can only roughly estimate the quality of the watch.
