Quartz
A quartz movement uses an electronic oscillator regulated by a quartz crystal to keep time. The crystal oscillator creates a signal with very precise frequency, which is why this type of movement is far more accurate than a mechanical watch. And it is easier and cheaper to produce, the reason why watches with a quartz movement are mostly cheaper than mechanical watches.

The first quartz clock was built in 1927 by Warren Marrison and J.W. Horton at Bell Telephone Laboratories. In the “who will be the first” race for a quartz wristwatch Seiko was first. In December 1969 they produced the world’s first commercial quartz wristwatch, the Astron. That was just before a union of 16 Swiss watchmakers introduced the Beta21 quartz movement that was used by Omega, Rolex and Patek Philippe in their watches.
