History Introduced in the late 1960s, the Seiko Lord Matic (LM) line was positioned just below the Grand Seiko and King Seiko ranges. It was designed to offer high-quality automatic movements and sophisticated case designs to the upwardly mobile professional class in Japan. The 5606 movement used in these watches is widely respected for its slim profile and robustness, serving as the base for many higher-end Seiko chronometers of the time. This specific example from November 1971 captures the essence of that innovative period. Payment and Shipping Payment must be completed within 1–3 days after purchase.
