Brand: Seiko Model: Lord Matic Reference Number: 5606-7190 Serial Number: 251837 Movement: Automatic Caliber 5606 Dial: Silver Sunburst Case Size: 36 mm Case Material: Stainless Steel Production Year: 1972 Condition: Excellent vintage condition with a pristine dial, sharp case geometry, and original bracelet. Dial and Hands The silver sunburst dial is in exceptional condition and retains a bright and reflective finish that catches the light beautifully. It features applied steel baton indices with black inlays that match the slender handset, creating a cohesive and legible layout. The dial is signed with the applied Seiko and LM logos, along with the Suwa Seikosha symbol above the six o'clock position. A framed day and date window is located at three o'clock, featuring a bilingual calendar wheel that displays days in both English and Kanji. Case and Crystal The stainless steel case features the sophisticated "Open Thru Glass" monocoque construction, designed to improve water resistance by eliminating a removable caseback. The case preserves its original sharp lines and factory finishing, showing only minor surface handling marks consistent with careful usage. The distinctive lugs slope gently to hug the wrist, while the crystal remains clear and provides an unobstructed view of the dial. The crown is original and sits flush against the case side. Movement Powering this watch is the high-grade Seiko Caliber 5606 automatic movement, a 25-jewel mechanism known for its reliability and slim profile. This movement features hacking capabilities and hand-winding support. Timegrapher readings indicate a rate of approximately -23 to -25 seconds per day, suggesting the movement is functioning solidly and offering reliable vintage performance. Strap The watch is fitted with its original stainless steel Seiko LM five-link bracelet, which is a significant collector's asset. The clasp features the embossed LM logo. The bracelet is currently sized to fit a wrist of approximately 19cm and shows moderate flexibility consistent with its age, remaining comfortable and secure on the wrist. Condition This timepiece is in excellent vintage condition. The dial is nearly flawless with no visible staining or aging spots. The case edges remain defined and have not been over-polished, retaining their original architectural character. The movement is running efficiently, and the overall presentation is that of a well-cared-for artifact from the 1970s. Dimensions The case measures 36 mm in diameter excluding the crown, offering a classic mid-size proportion that works perfectly for both dress and casual wear. Remarks This Lord Matic stands out due to its great condition and the presence of the original bracelet. The combination of the monocoque case design and the Kanji date wheel makes this a quintessential piece for enthusiasts of JDM (Japanese Domestic Market) horology. It is a refined daily wearer that embodies the high production standards of 1970s Seiko. History Introduced in 1968, the Seiko Lord Matic line was equipped with the sophisticated 56 series movement, which was also used in Chronometer-grade King Seiko and Grand Seiko models. The LM series was designed to bring high-end automatic watchmaking to the upwardly mobile professional class in Japan. Today, these watches are celebrated for offering immense value and historical significance, representing a time when Seiko was aggressively competing with, and often surpassing, their Swiss counterparts in accuracy and manufacturing quality. / Second Vintage SKU: SEI-SLJ-0164
