1. Observe the appearance of the watch, including dial, strap, glass, case and other details. The dial and scale lines of genuine watches should be clear and easy to read, and the material and workmanship of the strap should also be excellent. At the same time, check that the glass of the watch should be clean and bright, without bubbles, cracks or adhesion. The case should also be smooth and delicate, without flaws or damage.

2. Use professional watch testing equipment, such as testing the accuracy and movement of the watch. The movement of genuine watches should be accurate and stable, while fake watches may have problems such as large error or stop.

3. Check the serial number and anti-counterfeiting measures of the watch. Every watch has a unique number. You can check the model, specification, sales place and production date corresponding to this number on the official website of the watch manufacturer. At the same time, some brands will also set anti-counterfeiting marks or QR codes on watches, and the authenticity of watches can be verified by scanning QR codes or inquiring about relevant information.

4. Measure the weight of the watch. For genuine products, the materials used in manufacturing are strictly screened and refined, so the overall feeling of the watch is relatively heavy.

When buying watches online, it is recommended to choose regular platforms and merchants to ensure that you buy genuine watches. When you receive the goods, you can first check whether the outer packaging is in good condition, and then open the goods packaging to ensure that the watch meets the above requirements. If in doubt, you can contact the seller to return the goods in time.
