Grand Seiko SBGK007

Features

A new manual-winding caliber. A new slim profile.

Calibre 9S63 is a significant addition to the ever growing Grand Seiko family of movements. It has been eight years since the last manual-winding mechanical calibre in Grand Seiko and it has been worth the wait. Calibre 9S63 offers a small seconds hand at the nine o’clock position and a power reserve indicator at three o’clock. Calibre 9S63 has a power reserve of 72 hours and delivers an accuracy rate of +5 to -3 seconds a day.

A classic combination of a clean white dial and black crocodile strap create a perfect harmony. A curved dial with the hand-bent minute and power reserve hand gives the watch a classic look.
