Hold this watch up to a lamp, and nothing happens.
The dial is silver and features a fine sunburst finish, but the base is slightly grained. This scatters the light instead of reflecting it – the surface remains evenly bright from every angle, without the harsh glare cast by the highly polished dials of that era.
The practical utility is significant. A watch you want to read in the car, at your desk, or in the sun benefits from a surface that does not glare. The only luster on this dial comes from the applied indices – and that was precisely the intention.
The Lord Matic in the Seiko structure
The Lord Matic (LM) series was introduced in 1968 and occupied the premium mid-range at Seiko: above the Seiko 5, and below the King Seiko and Grand Seiko. It was manufactured at the Suwa plant – the same facility that was developing the Grand Seiko in parallel, while Daini was responsible for the King Seiko. This internal competition between Suwa and Daini was the driving force that brought Japanese watchmaking of the 1960s and 1970s to a world-class level.
Technically, the Lord Matic benefited immediately from this. The caliber 5606 belongs to the 56-series family – the same architecture upon which the King Seiko caliber 5626 and Grand Seiko caliber 5646 are built. The Lord Matic ran at a lower frequency and with simpler fine adjustment than its more expensive siblings, but the fundamental construction is identical. This explains why the 5606s are still considered exceptionally robust and watchmaker-friendly today – and why they are the most sought-after entry-level model for those wanting to collect Japanese watches from the classic era.
The caliber 5606A
- Automatic with additional manual winding – unlike older Seiko automatic movements, the 5606 can also be wound by hand
- Hacking seconds when the crown is pulled, allowing for precision time setting
- 23 jewels
- Quick-set for day and date
- Bilingual day wheel, Japanese and English
The bilingual version follows Japanese calendar conventions: Sunday is displayed in red, Saturday in blue – matching the markings in the Japanese calendar. A detail not found on European watches that reveals the watch's origin at a glance.
The combination of automatic winding, manual winding, hacking seconds, and quick-set features was remarkably comprehensive for 1974. Many European automatic movements in the same price range offered neither manual winding nor hacking seconds.
Dial and case
Beyond the matte surface, the dial thrives on reduction. The hour markers are applied, faceted batons with polished flanks whose edges refract light sharply – they are the only highlights on an otherwise understated surface. These are accompanied by slim polished hands and a fine center second hand.
A slightly raised track with a fine minute scale circles the edge, visually framing the dial. The text on the dial is sparse: SEIKO AUTOMATIC at the top, the LM signet with 23 JEWELS and the Suwa factory mark at the bottom. The calendar window at three o'clock is enclosed by an applied frame and displays the day and date side-by-side.
The stainless steel case follows the design language that Taro Tanaka formulated at Seiko as the "Grammar of Design": flat, sharply defined surfaces instead of rounded transitions, angular lugs with clearly visible facets, and a flat polished bezel. Tanaka’s principle was that every surface should reflect light in a defined direction – which only works as long as the edges remain sharp.
With a diameter of 36.2 mm, a lug-to-lug distance of 42.3 mm, and a height of 10.3 mm, the watch remains compact and fits unobtrusively under a shirt cuff.
Condition
This watch is in very good condition.
Technically flawless: It was professionally serviced in Japan in the spring/summer of 2026 – completely disassembled, cleaned, oiled, and regulated. The automatic winding, manual winding, hacking seconds, and quick-set for day and date function perfectly.
The dial is clean and uniform, with no spots, discoloration, or fading. The sunburst finish and grain are intact across the entire surface – the crucial point for matte dials, as damage there cannot be masked by reflections. The text is complete and sharp, the applied indices are firm and corrosion-free, and the calendar frame is intact.
The stainless steel case shows only light, age-appropriate signs of wear. The facets on the lugs and the transitions between the polished and brushed surfaces are preserved; the watch has not been over-polished. The case back shows fine marks from opening, and all engravings are complete and clearly legible. The crystal is clear.
It is fitted with a new black crocodile-embossed leather strap with light stitching.
