The pursuit of high accuracy has been the cornerstone of Grand Seiko\u2019s values since its first watch was created in 1960. Less than 10 years after its birth, Grand Seiko introduced the mechanical V.F.A., standing for \u201cVery Fine Adjusted.\u201d First used in 1969, this designation defined a Grand Seiko watch that was adjusted so skilfully that it achieved an astonishing monthly rate of \u00b11 minute.
