Dial and Hands
The dial is the standout feature of this timepiece, boasting a deep emerald green sunburst finish that graduates to a darker tone at the edges. It is adorned with faceted silver-tone applied hour markers that catch the light beautifully. The "LM" and "Seiko Automatic" logos are applied in silver, adding depth to the face. The hands are silver-tone batons with luminous inserts; they show noticeable oxidation and aging to the plating, which is consistent with an unrestored vintage piece of this age. A day-date window is positioned at 3 o'clock, featuring a bilingual English and Kanji day wheel, a desirable feature for collectors.
Case and Crystal
The stainless steel case features the classic Lord Matic silhouette with sharp, angular lugs and a polished finish. It remains in honest condition with visible scratches and contact marks throughout, preserving its original geometry without signs of over-polishing. The watch is fitted with a distinctive faceted mineral crystal (cut glass), which features vertical bevels that play with the light and distort the dial in a charming, kaleidoscopic way. The crystal shows some surface wear and scratches commensurate with its age.
Movement
Powering the watch is the high-grade Seiko Caliber 5606 automatic movement. This 23-jewel movement was a workhorse of the era, known for its slim profile and reliability. It features a hacking mechanism for precise time setting and offers reliable vintage performance. The rotor is marked clearly with Seiko branding.
Strap
The watch has been fitted with a new green leather strap with white contrast stitching and a silver-tone buckle. The color of the leather has been chosen to perfectly complement the green tones of the dial, giving the watch a fresh and cohesive look on the wrist.
Condition
This piece is in good vintage condition, wearing its history honestly. The case shows normal surface wear with scratches visible on the bezel and sides. The dial is well-preserved, though the hands show evident patina and oxidation. The movement is functioning well. The timegrapher results show the watch running between -21 and -29 seconds per day, which indicates a healthy movement running within vintage tolerances.
Dimensions
The case measures 37 mm in diameter excluding the crown, offering a classic mid-size profile that sits comfortably on a variety of wrist sizes. The lug-to-lug presence is substantial enough to feel modern while retaining vintage charm.
Remarks
This Seiko LM is a wonderful example of the "Disco Era" influence on watch design, characterized by the bold colored dial and the faceted "Cut Glass" crystal. While the hands show their age, the overall impact of the watch is undeniable. It represents a specific moment in Seiko's history where design experimentation met high-quality engineering. It is a watch that stands out in any collection and offers a unique wearing experience.
History
Introduced in 1968, the Seiko Lord Matic (LM) line was essential in solidifying Seiko's dominance in the automatic watch market. The 5606 movement found inside was a marvel of mass-production engineering, offering features like hacking and hand-winding that were often reserved for higher-tier watches. The LM series became a canvas for Seiko's designers, resulting in a wide array of case shapes and dial colors that defined the 1970s Japanese aesthetic. Today, these watches are celebrated for offering exceptional value and style, serving as a gateway to the rich world of vintage Seiko collecting.
