This serviced 1973 Seiko Lord Marvel 36000 Ref. 5740-8000 represents early-1970s Japanese horology, embodying the chronometric milestone and mechanical mastery of Suwa Seikosha's pinnacle high-frequency lineup. It is powered by the legendary 23-jewel Caliber 5740C manual-winding movement, historically renowned as Seiko's first true 36,000 bph (10-beat-per-second) caliber, engineered with Diashock shock protection and chronometer-grade architecture to deliver an exceptionally smooth sweep. Following a full mechanical service, it operates with silky-smooth hand winding, high-frequency stability, optimal efficiency, and crisp, dependable performance.
The hallmark of this timepiece is its factory-original silvery-white sunburst dial, capturing light with sharp precision across its pristine surface. Adhering to a pure, uncluttered time-only layout, it highlights textbook mid-century symmetry and understated executive sophistication. The dial is appointed with an applied gold-tone SEIKO logo, crisp "Lord Marvel 36000" typography with the iconic Suwa factory insignia, faceted baton hour markers with sleek black contrast inlays and a prominent double index at 12 o'clock, and slender baton hands.
The 35mm gold-plated 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 high-beat manual caliber. It comes paired with a premium cognac brown leather strap.
An exceptional 1973 Lord Marvel 36000 reference combining historical 36,000 bph high-beat engineering, pure time-only minimalist elegance, warm gold-tone executive aesthetics, and untouched factory-original dial integrity.
