Remarks This early Seiko Cronos stands out for its beautifully preserved silver sunburst dial and elegant typography.

History Introduced in the late 1950s, the Seiko Cronos line represents an important era in the development of Seiko's manual-wind dress watches. Produced by the Daini Seikosha factory, the Cronos was designed to be a slimmer, more refined alternative to the Marvel, featuring an elegant profile and a reliable, highly regarded movement architecture. Finding early examples with such pristine dials has become increasingly uncommon, making this 1959 piece a wonderful representation of mid-century Japanese horology. / Second Vintage SKU: SEI-CXX-0011
