A new manual-winding caliber. A new slim profile. 18K yellow gold case in the Grand Seiko Elegance Collection.
Caliber 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 caliber in Grand Seiko and it has been worth the wait. Caliber 9S63 offers a small seconds hand at the nine o’clock position and a power
reserve indicator at three o’clock. Caliber 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 brown crocodile strap create a perfect harmony. A curved dial with the hand-bent minute and power reserve hand gives the watch a classic look.
