The new watch adopts a through-bottom design, through the sapphire crystal case back, you can carefully appreciate the precise mechanism and exquisite finishing of the built-in movement. The 9SA5 is a high frequency (5 Hz) movement with a power reserve of up to 80 hours, representing the future of the Grand Seiko movement.

More importantly, the 9SA5 movement applies two key technologies to achieve more stable and precise timekeeping. One is the patented double-impact escapement system. The escapement wheel can transmit power directly to the balance wheel or the pallet fork to the balance wheel. At the same time, both the pallet fork and the escape wheel use MEMS technology ( MEMS) manufacturing, its operating efficiency is much higher than that of the traditional escapement system; the second is a non-card-spring balance wheel, which is equipped with four adjusting screws and a top-winding balance spring to help improve the isochronism of the movement, and it is more shock and friction .
