Hajime Asaoka “Chronograph”

Hajime Asaoka loves traditional chronographs. He has revived the sprits of them by creating “Chronograph”. The Chronograph has factors that 1950’s to 60’s masterpieces possess such as column wheel, horizontal clutch with carrying arm, brake lever, 2 buttons, sliding gear without omitting them. Asaoka has positioned chronograph mechanism on the dial side to show how the parts of chronograph move when they are operating and running. Of course, contrast of complicated dial side and simple back side shows the modern style of Hajime Asaoka. It has huge 15mm diameter balance wheel and also has huge barrel. That minimizes the decline of amplitude of balance wheel and keeps timing accuracy even when chronograph mechanism is operating.
