Seiko's original technology
SPRON is a Seiko original alloy. Used for the mainspring and hairspring, it was developed to be resistant to tear, corrosion, and wear.
Diashock is a structure developed to enhance the movement’s resistance to shocks. It is used as a bearing, such as for the balance wheel pivot, a section of the movement that is especially sensitive to shocks and jolts. With Diashock, the structure maintains high stability even when subjected to sudden shocks.
