History The Seiko caliber 6218 is a sophisticated 35-jewel automatic movement equipped with a day-date calendar and a hacking seconds function. This hacking mechanism stops the seconds hand when the crown is pulled out, allowing for precise time setting. The reference 6218-8010 belongs to the Seikomatic Weekdater line, which was identified in Seiko catalogs by the code MAWK. As a premium caliber from the 1960s, the 6218 is closely related to early Grand Seiko and King Seiko movements, establishing this model as a quintessential example of Seiko's mid-century mechanical achievement.
