This serviced 1973 Seiko Lord Matic Ref. 5606-7230 represents early-1970s Japanese horology, embodying the avant-garde design language and mechanical sophistication of Seiko's premier executive dress line. It is driven by the respected 23-jewel Caliber 5606 automatic movement from Suwa Seikosha, featuring manual winding, hacking seconds, and quickset day-date functionality. Following a full mechanical service, it operates with supreme precision, optimal efficiency, and flawless performance.
The hallmark of this timepiece is its factory-original gradient blue sunburst dial viewed beneath its genuine original faceted prism crystal, creating mesmerizing geometric reflections and light play across the rich surface. The layout is appointed with an applied silver SEIKO logo, the applied "LM" emblem, crisp "23 JEWELS" branding with the Suwa insignia, faceted block indices, matching pointed baton hands, and a framed domestic Kanji day-date window at 3 o'clock.
The 36mm stainless steel tonneau-cushion case preserves its sharp factory geometry, brushed upper surfaces, and polished bevels that sit comfortably and commandingly on the wrist. The watch head remains 100% authentic and unaltered, retaining its original factory dial, hands, faceted crystal, case, and crown. It comes paired with a premium textured black leather strap.
An exceptionally desirable 1973 Lord Matic reference combining reliable 56-series automatic engineering, rare original faceted prism optics, an untouched gradient blue sunburst dial, and classic JDM Kanji calendar execution.
