Grand Seiko caliber 9F61
Precision and simplicity form the very essence of the ideal timepiece, allowing it to fulfill a lifetime of commitment to its wearer. 9F was the first quartz movement to achieve this fundamental ideal.
Torque comparable to that of a mechanical movement makes the iconic wide hands of Grand Seiko possible. Improved second hand precision achieves greater positional accuracy on the dial against the markers. The sealed structure improves retention of lubricating oils.
