About the Masterpiece family
Masterpiece is Grand Seiko's top-tier collection, with extra hand-finishing of cases, dials and movements. The references here are Spring Drive models made in precious metals.
They include watches with the caliber 9R01, a hand-wound Spring Drive with an eight-day power reserve, and the 9R02, in platinum and rose gold. These are expensive, low-volume pieces, so complete papers, the original box and a service history from Grand Seiko make a large difference.
