Historical Context

The Seikomatic line marked Seiko’s push into more refined automatic watches during the 1960s, combining practical calendar functionality with clean, well-balanced case and dial design. Early Self Dater models are especially appreciated for their restrained styling, quality finishing and their place in the development of Seiko’s higher-grade mid-century mechanical watches.
