Seiko Lord Matic 5606-7580 Fume Green Sunburst Dial Year-1972 Vintage Watch

Up for consideration is the vintage Seiko Lord Matic Ref. 5606-7580, dating to 1972. Part of Seiko’s mid-tier premium line, the Lord Matic series bridged the gap between everyday Seikos and the higher-end King/Grand Seiko models.

This reference features a striking fume green sunburst dial, which shifts tones under the light from deep forest green to a radiant sunburst effect—a rare and highly desirable colorway among vintage Seikos. The case carries the sharp, angular lines typical of early 1970s Seiko design, paired with an integrated bracelet style for a bold yet elegant wrist presence.

Powering the watch is the automatic 5606 movement, equipped with both day/date complication and quickset function, making it practical for daily wear even today. A true collector’s piece, representing Seiko’s golden age of mechanical watchmaking.
