History Introduced in 1960, the Seiko Goldfeather was developed by the Daini Seikosha factory to compete directly with the Citizen Diamond Flake in the "thinnest watch" competition of the era. Upon its release, it successfully claimed the title of the world's thinnest center-second wristwatch. It marked a period of intense innovation at Seiko, paving the way for the high-end mechanical prowess that would define the brand in the coming decades. This specific example dates to September 1961, placing it early in the model's production run. / Second Vintage SKU: SEI-SGJ-0006
