Description
SEIKO vintage mechanical watch
MADE IN JAPAN
“Seiko” (精工) is a Japanese word meaning “precision,” “exquisite workmanship,” or “refined craftsmanship.”
It comes from the characters:
- 精 (sei) – fine, precise, refined
- 工 (ko) – craft, workmanship
Originally, Seiko’s watchmaking division was called Seikosha (精工舎), meaning “House of Precision.”
The name first appeared on a watch dial in 1924, shortened from Seikosha and keeping the core meaning; the company itself was renamed Hattori Seiko in 1983 and Seiko Corporation in 1990.
So the brand name literally ties directly to the idea of precision engineering—which is exactly what the company wanted to be known for in its watches.
About the Lord Matic Line
Seiko introduced the Lord Matic in 1968 as its mid-to-upper automatic line, slotted above the everyday Seiko 5 and Sportsmatic families and below King Seiko and Grand Seiko. It effectively took over from the Seikomatic range, and it was built at Suwa Seikosha around a new movement family: the slim 56xx calibres, running at 21,600 bph with hand-winding, hacking seconds and a quick-set calendar. The line was offered in three configurations — time-only (5601), date (5605) and day-date (5606).
From 1971 the Daini factory added the Lord Matic Special, built on the faster 28,800 bph 52xx calibres, while Suwa continued the standard 56xx line. Lord Matic production carried on into the second half of the 1970s before quartz pushed Seiko’s automatic dress watches aside. The line is remembered for sharply cut cases, sunburst dials and applied faceted markers — a lot of finishing for a watch that was never sold as a luxury piece.
About This Watch
This is a Lord Matic day-date, case reference 5606-7000, in a gold-plated case with a stainless steel back — the case back is marked SGP BACK ST.STEEL, SGP being Seiko’s own gold-plating designation. Inside is the automatic calibre 5606A, 23 jewels, beating at 21,600 bph, with hand-winding, hacking seconds and a quick-set day and date. The dial carries the printed 23 JEWELS text and the Suwa Seikosha whirlpool mark below the LM logo.
What sets this example apart is the case back. It is engraved 功績表彰記念 (in commemoration of a commendation for meritorious service) and 日本国有鉄道総裁 (President of the Japanese National Railways). Japanese National Railways — JNR, the state railway that ran the country’s network until it was broken up and privatised in 1987 — presented watches like this one to employees recognised for outstanding service. Seiko produced these case backs to order for JNR, which is why there is no serial number anywhere on this watch: the presentation engraving takes the place of the usual serial stamping. That also means the watch cannot be dated to a specific month the way a normal vintage Seiko can — reference 5606-7000 was in production from 1968 into the mid-1970s.
The dial is a silver-white sunburst with applied faceted baton markers and gold-tone hands, and the day-date window sits at 3 o’clock. The day wheel is the Japanese-market bilingual type, switching between English and kanji — one of the product photos shows it displaying 火 (Tuesday). The dial code printed at 6 o’clock reads JAPAN 5606-7001S; Seiko ran its dial codes as their own sequence, so a dial code that does not match the case reference is normal on watches of this period.
The watch is fitted with a vintage gold-tone expansion bracelet. It is not a Seiko-signed bracelet and is not original to the watch, but it suits the case and is period-appropriate.

Condition Report
The dial is excellent: clean and even, with no spotting, staining or lifting, and the applied markers and hands are bright and unmarked. The day and date discs are crisp and legible. The gold-plated case has held up well — the plating is intact across the top surfaces, with light honest wear on the high points of the lugs and along the bezel edge where a plated case always goes first. The crystal is clear, with only fine surface hairlines visible under direct light and no chips. On the steel case back the presentation engraving is sharp and fully legible, with a few light scratches in the brushed finish. The vintage gold-tone expansion bracelet shows more wear than the case: there is visible plating loss and brassing on several links and at the end pieces, which the product photos show in full.
This watch has recently been serviced by a professional watchmaker and keeps good time.
Comes complete with vintage gold-tone expansion bracelet*.
(*)Note: Stock bracelets are often shortened by previous owners and may not fit you(see bracelet size in the product images). We recommend adding a new Seiko lug width matched leather strap with your order.

Why Collectors Want This Watch Today
The Lord Matic is one of the better-value ways into vintage Seiko. The 5606A gives you hand-winding, hacking seconds and a quick-set day-date in a slim, well-finished case — a specification that a Seiko 5 of the same years does not match, at prices that are still reasonable.
The Japanese National Railways case back is what makes this particular watch interesting. Corporate and state presentation watches are a well-established collecting niche in Japan, and JNR pieces are among the most recognisable of them, carrying a specific story: someone was commended for their service on the national railway and went home with this watch. To be clear, these are not rare and they are not a price premium — JNR handed out Seiko and Citizen dress watches to staff throughout the 1960s and 1970s, standard 5606-7000 examples are common, and in Japan an engraved award back sells for about the same as a plain one, sometimes slightly less. It is also a different thing from a genuine railway-issue timepiece: the pocket watches actually issued to railway staff are a serious collecting field, while an employee award watch is an ordinary production watch with a commemoration added. What the engraved back gives you is not scarcity but a specific, legible piece of history attached to an otherwise anonymous dress watch — which is worth something to the right buyer, and nothing to a buyer who just wants a clean 1970s Seiko.
At roughly 36 mm in a gold-plated case, it also happens to be a genuinely wearable dress watch today — small by modern standards, correct for the period, and easy under a cuff.

About the watch factory
Seiko Group Corporation (セイコーグループ株式会社, Seikō Gurūpu kabushiki gaisha), commonly known as Seiko, is a Japanese maker of watches, clocks, electronic devices, and semiconductors. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world’s first commercial quartz wristwatch in 1969.
Seiko is widely known for its wristwatches. Seiko is one of the few watch companies that is fully vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko’s mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts internally.
Seiko offers one of the widest ranges of watch technologies in the world—quartz, kinetic, solar, mechanical, and Spring Drive—spanning everything from affordable everyday pieces to six-figure haute horlogerie. Over the decades it has launched multiple global brands, including Lorus, Pulsar, and Alba, while elevating its prestige through innovations like Spring Drive, which helped push Seiko into higher-end territory. In 2017, Grand Seiko was spun off into its own standalone luxury brand, while Credor remains part of Seiko’s own lineup, sold primarily in Japan. Seiko’s own global lineup now includes Grand Seiko, King Seiko, Prospex, Astron, Presage, and Seiko 5 Sports.
Among Seiko’s key lines, Seiko 5 (born in 1963) is the gateway mechanical series known for durability and value; Lord Matic defined 1970s style with faceted crystals and colorful dials; Astron remains Seiko’s flagship GPS-solar tech line; Presage focuses on traditional mechanical craftsmanship with enamel and urushi dials; and Prospex delivers professional-grade dive, field, and pilot watches often embraced by enthusiasts. At the top end, Grand Seiko emphasizes precision, Zaratsu polished design, and movements like Spring Drive, while King Seiko—revived in the 2020s—brings back sharp, elegant 1960s styling with modern calibres.
Finally, Credor represents Seiko’s pinnacle of artisanal watchmaking, producing low-volume pieces in precious metals and showcasing Japanese decorative arts and haute complications from the Micro Artist Studio. Beyond watches, Seiko has also produced various electronic devices and, historically, jewelry and eyewear—though those divisions have since shifted to other companies.
