History Introduced in 1968, the Seiko Lord Matic (LM) line was positioned as a sophisticated mid-range offering, sitting just below the King Seiko and Grand Seiko lines. It utilized the 5600 series movements, which were high-grade automatics that actually formed the base for many King Seiko chronometers. The LM series became famous for its variety of dial colors and case shapes, defining the Japanese "Grammar of Design" evolution into the adventurous styles of the 1970s. / Second Vintage SKU: SEI-SLX-0008
