This serviced 1969 Seiko King Seiko 45KS Ref. 45-7000 represents late-1960s Japanese horology, embodying the uncompromising Grammar of Design aesthetic and chronometric mastery of Daini Seikosha's pinnacle executive lineup. It is powered by the legendary 25-jewel Caliber 4500 manual-winding movement, a celebrated 36,000 bph ultra-high-beat masterpiece engineered with hacking seconds and chronometer-grade architecture. 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 silver dial, capturing light with sharp precision across its pristine surface. Adhering to an uncluttered time-only layout, it highlights textbook mid-century symmetry and understated executive elegance. The dial is appointed with an applied silver SEIKO logo, crisp "KS Hi-Beat" typography with the iconic Daini lightning bolt insignia, faceted baton hour markers with subtle black contrast accents and a prominent double index at 12 o'clock, and razor-sharp hands.
The 36mm stainless steel case preserves its sharp factory geometry, mirror-polished planar surfaces, and bold faceted lug contours that sit commandingly on the wrist in true Grammar of Design fashion. The watch head remains 100% authentic and unaltered, retaining its original factory dial, hands, crystal, case, and signed "KS" crown. It comes paired with a premium smooth black leather strap.
An exceptional 1969 King Seiko 45KS reference combining legendary 36,000 bph Daini ultra-high-beat chronometry, pure time-only symmetry, iconic Taro Tanaka case architecture, and untouched factory-original dial integrity.
