What are the types of mechanical movement? Guangzhou Pearl mechanical movement. Because the structure is imitated Japan’s Citizen mechanical movement, many buyers call it the “Citizen” movement, and they have slapped the ball! It is commonly called “disposable mechanical movement” in the circle. This movement imitates the Citizen movement, but does not inherit its quality.…
Japan imported disposable plastic quartz movement, commonly known as “black movement” in the circle. Most sellers call it “Japanese OS80 movement”. This movement, either not broken, can last a long time. Once it gets damaged, it can’t be repaired. The only way is to throw it away. Japanese original 2035 quartz movement, this type of…
How to deal with water in the watch? Because water will cause mechanical corrosion, it is very destructive. The sea water is even more untouchable. Even if the waterproof meter is indicated, there is only one year of waterproof protection. Because the waterproof ring of the watch will wear out after a whole year of…
There are several important related indicators when the watch uses the instrument to test the swing amplitude. Swing drop: The watch is in two states: full string and after 24 hours of actual running. Measure the swing amplitude changes of the five positions on two planes (top and bottom) and three vertical planes (bottom, left,…
The appearance of the watch can be inspected from the outer shell, the mirror, the dial, and the hour, minute, and second hands. The case should be free of blisters and obvious scratches, with symmetrical edges and corners. The screw joint between the back cover and the upper shell should be tight. The two watch…

What is quartz watch and Diving watch? Quartz watches It uses a “quartz crystal” as the oscillator, which has a high accuracy of time travel. Through the electronic frequency division to control the operation of the motor, drive the pointer. The electronic hand watch is a combination of an electronic movement and a quartz movement.…
Mechanical watch Timing instruments of mechanical vibration systems, such as pendulum clocks, pendulum clocks, etc. Its working principle is to use a vibration system with constant period and continuous vibration. Multiplying the vibration period by the number of vibrations, it is equal to the elapsed time, time = watch vibration period × number of vibrations.…
