Grand Seiko Quartz 9F Caliber

Seiko was one of the inventors of the quartz movement looking for the precision and simplicity of a perfect watch for day to day. The 9F was the first quartz movement to achieve this fundamental ideal.

The 9F quartz movements are instantaneous date change mechanisms, whose torque comparable to that of a mechanical movement makes possible the iconic Grand Seiko wide hands, enhancing their precision and legibility.

The Grand Seiko Quartz Caliber 9F and all its variants redefine the quartz watch, providing greater performance and greater durability making history in the watchmaking industry.
