This serviced 1975 Seiko Lord Matic Ref. 5606-8090 represents mid-1970s Japanese horology, embodying the sleek 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 royal blue sunburst dial, capturing light with sharp precision across its radiant surface. The layout is appointed with an applied silver SEIKO logo, the applied "LM" emblem, crisp "23 JEWELS" branding with the Suwa insignia, faceted baton hour markers with subtle contrast accents and a prominent double index at 12 o'clock, razor-sharp hands, and a framed domestic Kanji day-date window at 3 o'clock.
The 37mm stainless steel case preserves its sharp factory geometry, brushed hooded surfaces, slim polished bezel, and bold angular 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, and crown. It comes paired with a newly fitted stainless steel multi-link bracelet.
An exceptionally desirable 1975 Lord Matic reference combining reliable 56-series automatic engineering, a vibrant factory royal blue sunburst dial, distinctive hooded case architecture, and authentic JDM Kanji calendar execution.
