Watch selection method:
1, check the appearance
The appearance can be checked from the aspects of case, mirror, dial and pointer.
2. Sensitivity
The sensitivity of a watch refers to whether the balance wheel in the watch starts early or late.
3. Watch hands
There should be a certain gap between the pointer and the glass, between the three hands and between the pointer and the dial. If they rub against each other, it will affect walking.
Step 4 be tight
This is to check whether the parts of the needle moving parts are installed properly.
5. Walking sound
Listen to whether there is any abnormal sound when the watch moves. You can only judge whether there is any special problem with the watch, but you can't judge the quality of the watch.

British universities are worried that smart watches encourage cheating and prohibit students from wearing watches to take the final exam;
According to the French newspaper le figaro on February 9th, 20 15, many universities in Britain said that considering that more and more watches equipped with networking function may encourage students to cheat, they decided to ban students from taking exams with watches.
According to the report, with the continuous development of science and technology, more and more smart watches that can be networked have begun to enter the market. It is difficult to distinguish this smart watch from ordinary watches, so colleges and universities are worried that students will cheat by using this new technology. Buzzfeed, an American new media website, revealed that London University has started to provide I for Apple's upcoming listing.
The watch is very worried.
In a statement, the university expressed concern about the "instant response" function of iWatch smart watches, saying that this new technology "may cause problems in the 20 15 and later exams". Therefore, the University of London decided to treat watches and mobile phones equally, and students must also put their watches in their schoolbags when taking exams.
The report pointed out that the practice of the University of London is not the first. In 20 14, many universities in Britain prohibited students from bringing watches into the examination room. As compensation, these schools have also placed clocks in the examination room, which is convenient for students to check the time and grasp the progress of the exam.
