Grand Seiko SBGR301 (9S Mechanical)
A 3-day power reserve and refined design and functions in a larger case
This model retains the Grand Seiko design, with an increased case size giving the watch a greater sense of presence.
Equipped with the 9R61 caliber, the watch will run continuously for three days when fully wound, and utilizes the latest hairspring and MEMS manufacturing processes in its escapement to deliver higher stability of accuracy when in use.
Greater stability from the new slim-form watch case back provides an outstanding sense of security for the wearer.
