Micro Battery
Creating Time - Optimizing Time - Enriching Time
Seiko Instruments Inc. (SII), founded in 1937 as a member of the Seiko Group specializing in the
manufacture of watches, has leveraged its core competency in high precision watches
to create a wide range of new products and technologies.
Over the years SII has developed high-precision processed parts and machine tools
that pride themselves on their sub-micron processing capability,
quartz crystals that came about as a result of our quartz watch R&D,
and electronic components such as micro batteries.
Optimizing our extensive experience and expertise, we have since diversified
into such new fields as compact, lightweight, exceedingly quiet thermal printers,
and inkjet printheads, a key component in wide format inkjet printers for corporate use.
SII, in the years to come, will maintain an uncompromised dedication
to its time-honored technologies and innovations of craftsmanship, miniaturization, and efficiency
that meet the needs of our changing society and enrich the lives of those around us.
