Description

“Taking quartz into a new realm.”

Quartz caliber 9F is astonishingly accurate, with gain/loss measured in just seconds per year, but time-keeping accuracy is just one aspect of the many that place it among the finest quartz movements in the world.

The Twin Pulse Control Motor allows the use of the long and wide hands for which Grand Seiko is known, an achievement that before 9F was only possible with the high torque of a mechanical movement.

The Backlash Auto-Adjust Mechanism enables the second hand to advance precisely with no shuddering, by incorporating a hairspring device traditionally used usually only in mechanical movements.

The Instant Date Change Mechanism changes the date display in 1/2000th of a second.

The Super Sealed Cabin prevents dust entering the movement when the battery is changed and prolongs the life of the lubricating oils that ensure smooth operation of the gear train.

This is a timepiece of exceptional quality with features that were previously unimaginable in a quartz movement. Combining superior functionality and meticulous detail, Caliber 9F takes the quartz watch into a new realm.
