SEIKO — VINTAGE SEIKOMATIC WEEKDATER AUTOMATIC, c. 1965

Vintage Seiko Seikomatic Weekdater Automatic Watch, circa 1965, featuring a champagne sunburst dial, applied gold-tone hour markers, and an unusual day/date arrangement. Powered by Seiko's 26-jewel automatic movement, this elegant mid-century Japanese timepiece exemplifies the refined watchmaking of Seiko's early mechanical era. The case states waterproof, but it is untested and a sixty year old watch. Seals are likely in excellent condition, but rehoming you don't submerge it.
