From Kintaro Hattori's 1881 Tokyo shop, Seiko grew into a vertically integrated manufacturer that reshaped both mechanical and electronic watchmaking. Grand Seiko, landmark dive watches, the 6139 automatic chronograph, and the 1969 Astron quartz watch chart a history of relentless competition and invention that left an unusually broad vintage catalog.
