Spring Drive: Grand Seiko 's unique innovative movement is a groundbreaking watch that overturns conventional notions. It is a hybrid mechanism that combines the power of a mainspring with the precision of quartz, and is the only technology in the world that combines the natural movement of a mechanical watch with the precision of quartz.

Quartz: A movement that combines high precision and durability, exceeding the limits of typical quartz watches. The 9F quartz, which was born in 1993, is made of precision parts and assembled by craftsmen by hand, and has performance that defies the common sense of quartz. It boasts an extremely high accuracy of ±10 seconds per year, achieving accuracy that far surpasses that of typical quartz watches.

Grand Seiko 's quartz models first appeared in the mid-1990s. Since Seiko released the world's first quartz watch, the Quartz Astron, in 1969, the technology has been further refined and evolved into even more accurate models.

Grand Seiko quartz watches are especially renowned for their "9F series" movements. Introduced in 1993, the 9F movement is packed with highly advanced technology. Equipped with a powerful motor, it is characterized by the smooth operation of models with larger and heavier hands than regular quartz watches.

Quartz models using this 9F movement achieve an incredible accuracy of ±10 seconds per year, providing accurate time for a long period of time. Grand Seiko quartz models combine high precision with beautiful design, setting them apart from other quartz watches.
