About SII

Seiko Instruments Inc., also known as SII, is at the forefront of mechanical technology in the world. As a leading global manufacturer of quartz watches, it is also involved in the field of computer printers. SII's performance is particularly outstanding in electronic components, especially quartz oscillators. Among numerous electronic component manufacturers, there are few that can compete with SII and Japan's Seiko crystal oscillator in the global market at the same level, and Japan's KDS is one of them. Although SII produces relatively few quartz crystal oscillator models, this has not affected the excellence of its product quality. The quartz crystal oscillator produced by SII can definitely rival the quality of any major Japanese brand, and even compete with top brands globally.
