History Introduced in 1968, the Lord Matic line was Seiko's mid-tier luxury offering, sitting directly beneath the Grand Seiko and King Seiko lines. It was designed to bring high-quality automatic movements and sophisticated case designs to a broader audience. The 5606 movement inside this watch was one of Seiko's most successful calibers, known for its slim profile and reliability. These watches were the daily drivers of the Japanese businessman in the 1970s and have since become cult classics for their variety of dial colors and case shapes. / Second Vintage SKU: SEI-SLJ-0046
