This timepiece is a magnificent mechanical artifact from April 1973, as confirmed by the serial number 348501 stamped on the stainless steel caseback.The Lord Matic (LM) collection represented Seiko’s premium mid-tier luxury lineup during the golden era of mechanical watchmaking, utilizing high-spec calibers produced by the famous Suwa Seikosha factory. It houses the upscale Caliber 5606, a sophisticated technical soul boasting 23 jewels, hacking capability for micro-second synchronization, and a hand-winding option that elevates it far above standard vintage automatics.
The case architecture is outstanding, featuring a beautifully contoured stainless steel cushion profile with sharp mirror-polished edges that hug the wrist perfectly on a stitched black leather strap. The dial is an absolute masterclass in visual depth, showcasing a stunning slate smoke-blue sunburst finish. It is exquisitely appointed with towering, three-dimensional faceted block indices, polished baton hands, and an iconic applied polished "LM" crest. At 3 o'clock sits the signature bilingual English/Kanji JDM day-date window. This professional-grade luxury instrument was built exclusively for the Japanese Domestic Market (JDM).
