Seiko Lord Matic 5606-5010 buying guide

The 5606-5010 belonged to the Lord Matic line, positioned below King Seiko and Grand Seiko while retaining a high-grade automatic format. Its 1969-1972 production span crosses the visual shift from the late 1960s into the bolder 1970s, and the TV-screen or cushion-shaped steel case makes that transition visible.

The wide brushed bezel is not background decoration. It controls the entire look of the watch and makes lost brushing or rounded edges immediately consequential. A silver sunburst dial brings out the case architecture, while deep blue and black versions produce a heavier, more graphic object.

The dial carries the largest condition premium. Deep blue, deep black and silver sunburst are established configurations, but colour alone does not justify paying past damage, refinishing or mismatched furniture. A clean silver dial outranks a damaged blue one, and a convincing black dial outranks an attractive redial.

Case preservation comes next because the 5606-5010 depends on broad brushed surfaces and defined transitions. Polishing that softens the TV-screen outline removes the feature that separates this reference from a conventional round Lord Matic. The 5606A must also be present, though the service history remains unknown without documentation.

Start with the dial and case as a pair. The strongest purchase has an undamaged dial, applied furniture that belongs together and a broad bezel whose brushing remains legible; minor external wear matters less than refinishing or a case polished out of shape.

Between a cleaner 40 mm example and a more worn 41 mm example, buy the cleaner watch rather than treating the measured millimetre as a separate variant. Between dial colours, silver sunburst makes the geometry easiest to read, while blue and black put more emphasis on the applied markers. The recommendation is simple: take the best preserved dial and case, not the most dramatic colour.
