What is the meaning of the pendulum of a watch and what does the frequency of 28800 vibrations represent?

On the one hand, we know what vibration frequency is. Vibration frequency, in layman's terms: vibration frequency. Usually refers to the number of times an organism swings infinitely in one second. The operation of an automatic mechanical watch is usually composed of a combination of movement (mainspring) transmission (rack system) and automatic adjustment safety device (escapement structure type, pendulum oil wire). Propulsion is directed from the mainspring in conjunction with the transmission to the escapement wheel. Combined with the swing of the oscillating weight, the final output of the propulsion force is completely consistent; every time the oscillating weight swings, the wandering crystal strikes the rod and unlocks the escapement wheel, providing propulsion for a new swing before locking again. In automatic mechanical watches, this process occurs several times a second, and this frequency is the running vibration frequency we usually mention. Watch amplitude is a professional term. Amplitude, also called swing, usually refers to the maximum horizontal displacement of a vibrating organism from a specific position of static equilibrium. Watch swings are constantly changing and their safety and size are key to a number of fundamental elements. The main key lies in the tightness of the spring. The fuller the spring, the higher the swing. Generally speaking, it is felt that when the string is full horizontally, the swing amplitude is more suitable for 230~330 degrees. In actual manufacturing and inspection, swing amplitude drop is generally calculated using a swing meter, swing recorder and special testing equipment for direct and accurate measurement, which can be used together with a calibration meter or swing recorder and other testing equipment. At the same time, special testing equipment can directly print out the amplitude and average daily difference values ​​​​on the recording paper. If you process this data correctly, you can have more consistent results. Using an amplitude meter to test the amplitude is a relatively simple and direct method, but the test accuracy is relatively low. This is because the range of changes in the estimated needle or point-like strong echo of the amplitude meter is not completely consistent.

What does the vibration frequency of 28800 represent?

The escape wheel swings 28,800 times per hour, which lasts 3,600 seconds per hour. It swings 8 times per second, which can be interpreted as the second hand jumping up and down 8 times per second. For this reason, compared with quartz watches, the frequency of the watch is 4 Hz, which is also a dedicated frequency for automatic mechanical watches. Domestic mechanical watches usually have frequencies of 20000, 21600, and 28800, which means they swing 5, 6, or 8 times per second. Zenithelprimemo frequency exceeds 36,000. The higher the frequency, the more consistent the walking times are. To be precise, this also usually refers to the frequency at which the rotor oscillates. The higher the swing frequency, the less affected by the swing of external structures, which means the watch is more consistent and the easier it is to produce and process the watch.
