This serviced 1974 Seiko 5 Actus SS Ref. 6106-7520 represents mid-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 vivid cobalt blue 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 contrast accents 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 37mm 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 watch head remains 100% authentic and unaltered, retaining its original factory dial, hands, crystal, case, and crown. It comes paired with a premium textured black leather strap.
An exceptionally desirable 1974 Seiko 5 Actus SS reference combining robust 23-jewel hacking automatic horology, a striking factory cobalt blue sunburst dial, iconic recessed-crown styling, and bold cushion-tonneau case architecture.
