This serviced 1966 Seiko Seikomatic-R Ref. 8346-8000 represents mid-1960s Japanese horology, embodying the refined executive elegance and mechanical ingenuity of Seiko's prestigious business automatic lineup. It is powered by the highly regarded 30-jewel Caliber 8346 automatic movement, engineered with a slim profile, Diashock shock protection, manual winding capability, and an efficient calendar mechanism. Following a full mechanical service, it operates with supreme precision, optimal efficiency, and dependable performance.
The hallmark of this timepiece is its factory-original silver sunburst dial, capturing light with sharp precision across its radiant surface. The layout is appointed with an applied silver SEIKO logo, crisp printed "Seikomatic-R" and "Diashock 30 Jewels" typography, faceted baton hour markers with an intricately textured double index at 12 o'clock, razor-sharp hands, and a framed day-date window at 3 o'clock.
The 36mm stainless steel case preserves its sharp factory geometry, slim polished bezel, and gracefully tapered lug contours that sit comfortably and commandingly on the wrist. The watch head remains 100% authentic and unaltered, retaining its original factory dial, hands, crystal, case, crown, and 30-jewel movement. It comes paired with a premium textured black leather strap.
An exceptionally well-preserved 1966 Seikomatic-R reference combining high-grade 30-jewel automatic engineering, manual-winding capability, an untouched silver sunburst dial, and quintessential mid-century Japanese dress aesthetics.
