An automatic mechanical in a new 40mm case design

A black dial gives a more compact look. The strong three-dimensional indexes are tightly arranged to the outside of the calendar frame, creating harmony with the presence of the case, balance and a stately profile. The case design has a sense of presence and luxury following the standard design of Grand Seiko.

The caliber 9S65 "Mechanical automatic winding 3 Days" lasts 72 hours at maximum winding, adopting the latest hydraulic spring and escapement (MEXT) by MEMS method, creating greater stability and improved accuracy. The back of the see-through case, allows the owner to enjoy the precise movement.

This model combines the presence and wearability in a well-balanced manner with high legibility. This model can endure generations as a lifetime timepiece that carves important moments together.
