The three movements at the heart of Grand Seiko

9SMechanical

One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Grand Seiko's expert watchmakers.

9RSpring Drive

Spring Drive’s unique movement technology generates power through a mainspring like other mechanical watches but combines this with the Tri-synchro Regulator for extraordinary precision.

9F Quartz

The ultimate quartz movement. Caliber 9F incorporates several unique technologies that raise the performance of quartz to the high standards of Grand Seiko.
