History Introduced in the late 1960s, the Lord Matic (LM) line was positioned just below the King Seiko and Grand Seiko lines, offering high-end movement technology in more accessible and varied designs. The 5606 movement inside this watch was one of Seiko's most successful automatic calibers, known for its thin profile and reliability. This specific example, produced in 1975, captures the mature design language of the mid-70s Seiko catalog. / Second Vintage SKU: SEI-SLJ-0116
