Another YouTube video on Grand Seiko 9R (Springdrive) manufacturing and assembly
This video shows Seiko making their parts inhouse: quartz crystals, hands, indexes, dials, cases, etc.
Also the Zaratsu polishing of the cases and the hairline polishing of the hands and indexes is shown.
Grand Seiko 9R calibre
