How accurate is the timing?

Time is naturally divided according to astronomical phenomena: the earth revolves around the sun, so there are four seasons; the moon is cloudy and sunny, so we can divide day and night.

In order to measure time more accurately, humans have invented various artificial methods, such as the sundial or the trickle to measure time with the flow of water. Since 1657, the use of oscillatory systems in mechanical movements has improved the efficiency of measuring time.

After that, the electronic revolution brought decisive influence. In 1967, a Swiss research group designed and developed the first electronic timepiece movement, widely known as the quartz movement. This technology, which uses electricity from batteries, opened the way for diodes and subsequent liquid crystal displays.

Due to the high vibration frequency (32 kHz) of quartz watches, they are extremely accurate, with an error (faster or slower) of less than one second per day.

In contrast, mechanical wristwatches typically oscillate at 3 or 4 Hz, with a daily error of less than 10 seconds.
