Watch Movement Rator Magnet
Different historical periods each have their own timer utility. The sun or the moon were used to time in the early days of astronomy, and then fluid was used to time. As a modern invention, quartz watches have numerous advantages, including a simple structure, ease of assembly, long endurance, shock resistance, accurate timepieces, and a low price. Micro Samarium Cobalt magnets have long been used as watch movement rotor magnets in quartz watches.

As a modern invention, quartz watches have numerous advantages, including a simple structure, ease of assembly, long endurance, shock resistance, accurate timepieces, and a low price. Micro Samarium Cobalt magnets have long been used as watch movement rotor magnets in quartz watches.
The quartz watch's energy source and time base are a battery and a quartz oscillate, respectively. Then, using a CMOS circuit as the core, display time using hands or numbers. In 1880, French physicist Pierre Curie discovered the piezoelectric effect of quartz crystal, laying the groundwork for the invention of the quartz watch. The battery in a quartz watch supplies current to the microchip circuit, causing the quartz crystal to vibrate 32768 times per second.
The microchip circuit detects oscillations and converts them into electric pulses at a rate of one per second. To convert electrical energy to mechanical power, an electric pulse drives a stepper motor, which then turns gears and gears further to sweep hands around the face to keep time. Watch movement rotor magnets of quartz watches should be difficult to demagnetize and have superior time stability, so micro Samarium Cobalt magnets have long been thought to be the best options.
