History Introduced in 1968, the Seiko Lord Matic line was created to serve as the sophisticated mid-tier offering for the brand, positioned just below the prestigious King Seiko and Grand Seiko collections. The LM series was highly successful, favored by businessmen for its elegant proportions and reliable performance. Crucially, the Lord Matic was powered by the 56-series movement family, a robust and advanced automatic caliber that Seiko also utilized as the foundational architecture for the chronometer-certified movements in their higher-end lines. Today, the Lord Matic is celebrated by collectors for offering remarkable mechanical quality and incredibly diverse, daring dial designs that perfectly encapsulate the spirit of 1970s horology.
