Grand Seiko Heritage Collection

Hi-Beat 36000 with a true GMT: the movement beats ten times a second, twice the industry norm, which is punishing to build and gives noticeably better rate stability, while a fourth hand tracks a second time zone independently. The steel case has every surface Zaratsu-polished by hand against a rotating tin plate, producing mirrors with no distortion, and the hands are cut and faceted individually.
