Method of identifying watches:

1. First, look at the package, rectangular box, black and white tone, with pictures of models printed on four sides.

2, at the bottom is a bar code with a watch chart and model (you can scan the code to get product information) and an official website. Open the outer package, and there is an inner package with the words klasse14 on the front.

3. Looking at the watch, it is easy to see that the dial is concave. This design is really good, and it can capture light well.

4, the pointer inside is very special, and the minute hand is bent and folded. The clasp is a single folding clasp with the designer's name printed on it.

5, and then look at the back, wrapped in a thin layer, you can see that the watch series is printed with the designer's signature, and an eagle (the source of the design concept of the watch)

The following points should be paid attention to when purchasing:

1. Visually inspect the shell, surface and needle. There are no "trachoma" and scratches. The coating is bright and has no color difference. The back cover should be tightly screwed.

2. Starting performance. Rotate the winding handle slowly and watch the second hand at the same time. Generally, the fewer winding revolutions the second hand starts, the better the starting performance of the watch.

3. the last article. When loading, the feel should be relaxed and there is no noise. In addition to the phenomenon of slipping after the automatic watch is wound, the general watch spring should be able to be wound without slipping.

4. set the needle. The handle should be comfortable when pulling the needle, and it is not good to be too tight or too loose. The indication of hours and minutes should be coordinated (when the hands are aimed at 3, 6, 9 and 12 characters respectively, the minutes should not deviate from the 12-character 4-frame), and the hours, minutes and seconds should not touch each other.

5. phonetic notation. After the watch is fully wound, listen to the sound with your ears, which should be clear, symmetrical and without noise, and do not change with the direction.

6. Travel time accuracy. It needs to be measured with special instruments. Some large state-owned stores have the service of measuring for customers. When purchasing, you can ask the salesperson to detect the travel time accuracy and position error.

product maintenance

1. Any watch should not be worn in warm water or bathroom, even if your watch is waterproof, because the sealed rubber of the watch is easy to age when heated, and the surrounding water vapor molecules are relatively small, which can easily penetrate into the watch case, causing internal mechanical damage.

2. If the watch is abnormal, it should be sent to a special watch shop for inspection immediately.

3. Different watches should be worn on different occasions. For example, it is best to choose a sports watch with excellent waterproof and shock resistance when exercising.

4. It is best to put desiccant in the place where watches are placed, but avoid using chemicals such as mothballs and insect repellents.
