This serviced 1973 Seiko Lord Matic Ref. 5606-7310 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 emerald green dial viewed beneath its genuine original faceted prism crystal, creating mesmerizing geometric reflections and light play across the 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 with distinctive warm gold-toned accents, matching pointed baton hands, and a framed bilingual English/Kanji day-date window at 3 o'clock.
The 36mm stainless steel case preserves its sharp factory geometry, brushed upper surfaces, polished bevels, and bold angular contours that sit commandingly on the wrist. The timepiece remains 100% factory-correct and complete, retaining its original dial, hands, faceted crystal, case, crown, and rare factory-original stainless steel Lord Matic multi-link bracelet.
An exceptionally desirable 1973 Lord Matic reference combining reliable 56-series automatic engineering, rare original faceted prism optics, an untouched gradient emerald green dial, and full original bracelet integrity.
