History Introduced in 1968, the Lord Matic (LM) line was Seiko's mid-range luxury offering, utilizing the sophisticated 5600 series movements which were thinner and more advanced than many competitors of the time. The line was essential in bringing high-end automatic watches to the mainstream Japanese public and remains a favorite among vintage enthusiasts for its variety of dial textures and robust build quality. / Second Vintage SKU: SEI-SLJ-0034
