It was the first substantial line to utilize the 56 series movement, which was thinner and more capable than its predecessors. The Lord Matic series became a canvas for Seiko's design experiments in the 1970s, resulting in some of the most creative and colorful dials in the brand's history. / Second Vintage SKU: SEI-SLJ-0004
