It features a fine, cross-hatched pattern reminiscent of a linen weave—vertical and horizontal lines that overlap and refract light in two directions simultaneously.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWhen you tilt the watch, the luster does not travel across the surface as a single beam, but as a shimmer across the entire dial. This is a completely different effect than that of the standard Seiko dials of those years—and the reason why linen dials are specifically sought after today.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eA case without a back\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe case back bears an instruction directed not to the wearer, but to the watchmaker: \u003cstrong\u003eOPEN THRU GLASS, PUSH SET LEVER, PULL STEM.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis watch cannot be opened from the back. The back is not a lid, but part of a one-piece case body. To access the movement, one must remove the crystal from the front and work through the dial side.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe reason is structural. A watch case usually has three points where water can penetrate: the crystal, the crown, and the case back. The case back gasket is the most vulnerable because it runs the entire circumference and must be replaced at every service. Seiko solved this in several series of the late 1960s by eliminating the case back entirely. The fact that this case says \u003cstrong\u003e\"WATERPROOF\"\u003c\/strong\u003e instead of the \"WATER RESISTANT\" used from 1970\/71 onwards is a consequence of this—and at the same time, evidence for its dating.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eFor the collector, this has a practical consequence: because the dial side is exposed during every service, many of these watches today bear traces of careless handling. With a linen dial, that would be particularly bitter, as every scratch interrupts the structure. Here, it is intact across the entire surface.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eThe Lord Matic in the Seiko hierarchy\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe Lord Matic (LM) series appeared in 1968 and occupied the upscale middle market at Seiko: above the Seiko 5, below King Seiko and Grand Seiko. It was manufactured at the \u003cstrong\u003eSuwa factory\u003c\/strong\u003e—the same plant that developed the Grand Seiko in parallel, while Daini was responsible for King Seiko. This internal competition between Suwa and Daini was the engine that brought Japanese watchmaking of the 1960s and 1970s to a world-class level.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTechnically, the Lord Matic benefited directly from this. The caliber 5606 belongs to the \u003cstrong\u003e56 movement family\u003c\/strong\u003e—the same architecture upon which the King Seiko caliber 5626 and Grand Seiko caliber 5646 are based. The Lord Matic ran at a lower frequency and had simpler fine adjustment than its more expensive siblings, but the fundamental construction is the same.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe fact that Seiko gave this mid-range line an elaborate one-piece case and a textured dial in 1970 speaks volumes about the level of ambition in those years.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eThe caliber 5606\u003c\/h3\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eAutomatic with additional manual winding\u003c\/strong\u003e – unlike older Seiko automatic movements, the 5606 can also be wound by hand\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eHacking seconds\u003c\/strong\u003e when pulling the crown, allowing for precision setting\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003e25 jewels\u003c\/strong\u003e as stated on the dial\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eQuick-set for day and date\u003c\/strong\u003e\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBilingual day wheel\u003c\/strong\u003e, Japanese and English\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eThe bilingual version follows the Japanese calendar convention: Sunday in red, Saturday in blue.

The hour markers are slender, applied batons with dark-finished flanks—they form the only harsh contrast on the bright surface. Accompanying them are equally slender hands and a fine central seconds hand.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe dial is signed with the SEIKO logo at the top and the LM insignia with \u003cem\u003eLORD MATIC \/ 25 JEWELS\u003c\/em\u003e and the Suwa factory mark at the bottom. The calendar window at three o'clock is framed by an applied border and displays the day and date.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe stainless steel case has a softly rounded tonneau shape with broad, flat-extending lugs and a narrow polished bezel. At 35.7 mm in diameter with a \u003cstrong\u003elug-to-lug of only 39.7 mm\u003c\/strong\u003e and a height of 9.4 mm, the watch is exceptionally compact—dimensions that are rarely found today and that sit neatly even on slender wrists.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eCondition\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eTechnically flawless. The watch was professionally serviced in Japan in the spring\/summer of 2026—fully disassembled, cleaned, oiled, and regulated. Automatic winding, manual winding, hacking seconds, and the quick-set for day and date work perfectly.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe dial is well-preserved: the linen structure is consistent across the entire surface and undamaged, the color tone is uniform with no spots or fading. The lettering is complete and sharp, the applied indices are firm and without corrosion, and the calendar frame is intact. Particularly with a monocoque case, this is the most important finding—it proves that the watch has been properly maintained over the decades.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe stainless steel case shows age-appropriate signs of wear, somewhat more clearly on the lug edges and the bezel. The basic shape has been preserved; the watch has not been over-polished. All case back engravings—reference 5606-7130, serial number, workshop instructions, Suwa mark—are complete and clearly legible. The crystal is clear.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe watch is mounted on an aftermarket stainless steel bracelet; it is not the original Seiko band.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul dir=\"ltr\"\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBrand \/ Line:\u003c\/strong\u003e Seiko, Lord Matic (LM)\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eReference:\u003c\/strong\u003e 5606-7130\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eSerial number:\u003c\/strong\u003e 076345\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eProduction date:\u003c\/strong\u003e July 1970\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Seiko caliber 5606, automatic with manual winding, 25 jewels, hacking seconds\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Suwa Seikosha, Japan\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, central seconds, day and date with quick-set, bilingual day wheel (Japanese\/English)\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, one-piece monocoque case (movement removal from the front through the crystal)\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eDiameter (without crown):\u003c\/strong\u003e 35.7 mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 9.4 mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLug-to-lug:\u003c\/strong\u003e 39.7 mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eLug width:\u003c\/strong\u003e 19 mm\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eWeight (incl. band):\u003c\/strong\u003e 63 g\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e Aftermarket stainless steel bracelet\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Acrylic\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eService:\u003c\/strong\u003e Spring\/Summer 2026, Japan – full disassembly, cleaning, oiling, regulation\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch3 dir=\"ltr\"\u003eFor whom\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eFor anyone who appreciates textured dials.
