This serviced 1973 Seiko Lord Matic Ref. 5606-7320 is a spectacular example of 1970s Japanese horology, embodying the absolute height of Seiko's retro-executive design. It is driven by the premium 23-jewel Caliber 5606 automatic movement, featuring hacking and hand-winding capabilities for robust mechanical precision.
Following a full service, the caliber operates with optimal efficiency. The 100% original emerald green gradient dial interacts beautifully with the watch's standout feature: its original faceted glass crystal. The geometric facets slice light across the sunburst surface, highlighting the applied gold-tone indices and the bilingual JDM day-date window at 3 o'clock.
The stainless steel case is beautifully preserved, retaining its sharp factory geometry and aggressive lug contours. The watch head remains entirely factory-correct, preserving its original dial, crystal, case, and crown. It comes flawlessly paired with a vintage-style stainless steel multi-link bracelet.
Collectors fiercely pursue faceted Lord Matic models for their dramatic 1970s aesthetic and mechanical depth.
