Seiko Institute of Horology / What is quartz ?
The Seiko Institute of Horology (now The Seiko Museum) was opened in 1981 as part of a project to commemorate the 100th anniversary of the founding of Seiko. The museum displays research materials related to time and timepieces produced in Japan and other countries around the world.

Quartz possess a property whereby it deforms when an electrical voltage is applied, and depending in the shape and size, an extremely accurate specific frequency is generated. The quartz watch utilizes this quartz oscillation. On account of the extremely accurate ticking away of time with an error of just several seconds per month, and the fact that they can be made in thin profiles and light weight, nowadays almost all of the world's watches have come to be quartz watches.
