Seiko’s technology
Diashock
Diashock is a structure developed to enhance shock resistance. It is used in the movement of a mechanical watch as a bearing, such as for the balance wheel pivot, which is especially sensitive to shocks and vibration. The structure maintains high stability even when sudden shock is applied.
SPRON
Spron is an alloy developed with the aim of being resistant to tear, corrosion and wear to make mechanical watches that can be used over a long period of time, Seiko has worked on the development and manufacturing of springs for more than half a century, and it has adopted this proprietary material to be used for the mainspring and hairspring.
