History The Seiko Goldfeather was introduced in 1960 as part of an industry competition to produce thinner mechanical watches. Upon its release, the Goldfeather held the record for the world's thinnest three-hand watch until it was surpassed in 1962. The Goldfeather was Seiko's answer to the ultra-thin watch trend of the early 1960s, making it a historically significant and sought-after model among collectors of mid-century Japanese horology.
