This serviced 1973 Seiko Lord Matic Ref. 5606-7290 represents early-1970s Japanese horology, embodying the sleek design language and mechanical sophistication of Seiko's premier executive dress line. It is powered by the upgraded 25-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 royal blue sunburst dial, capturing light with sharp precision across its radiant surface. The layout is appointed with an applied gold-tone SEIKO logo, the applied "LM" emblem, crisp "25 JEWELS" branding with the Suwa insignia, bold applied three-dimensional faceted block hour markers with warm accents, matching hands, and a framed bilingual English/Kanji day-date window at 3 o'clock.
The 36mm stainless steel cushion-tonneau case preserves its sharp factory geometry, brushed upper surfaces, and polished flanks that sit comfortably and commandingly on the wrist. The timepiece remains 100% factory-correct and complete, retaining its original dial, hands, crystal, case, crown, and rare factory-original stainless steel multi-link bracelet.
An exceptionally desirable 1973 Lord Matic reference combining the upgraded 25-jewel 56-series movement, a captivating factory royal blue sunburst dial with gold-accented markers, fluid cushion-tonneau architecture, and full original bracelet integrity.
