This serviced 1973 Seiko 5 Actus SS Ref. 6106-7580 represents early-1970s Japanese horology, embodying the dynamic design language and mechanical innovation of Seiko's iconic JDM Actus lineup. It is powered by the respected 23-jewel Caliber 6106 automatic movement from Suwa Seikosha, featuring Diashock shock protection, a hacking "Second Setting" mechanism, and an intuitive push-crown quickset day/date system. Following a full mechanical service, it operates with supreme precision, optimal efficiency, and dependable performance.
The hallmark of this timepiece is its factory-original silvery-white sunburst dial, capturing light with sharp precision across its radiant surface. The layout is appointed with an applied silver SEIKO logo, the applied "5 Actus" shield emblem, crisp "SS 23 JEWELS" typography accompanied by the Suwa factory insignia, faceted baton hour markers with sleek black contrast inlays and a prominent double index at 12 o'clock, razor-sharp hands, and a framed bilingual English/Kanji day-date window at 3 o'clock.
The 38mm stainless steel cushion-tonneau case preserves its sharp factory geometry, brushed upper surfaces, and polished flanks that sit comfortably and commandingly on the wrist. True to signature Actus architecture, it features a flush-recessed crown at 4 o'clock. The timepiece remains 100% factory-correct and complete, retaining its original dial, hands, crystal, case, crown, and rare factory-original stainless steel multi-link bracelet.
An exceptionally desirable 1973 Seiko 5 Actus SS reference combining robust 23-jewel hacking automatic horology, an untouched silvery-white sunburst dial, iconic recessed-crown cushion architecture, and full original bracelet integrity.
